Scientific and technological innovation building a strong steel country

 China's steel industry has a good foundation for high-quality development of galvanized steel pipe. From the scale of production, China already has the conditions and foundation to solve the production capacity and output problems of iron ore, coke, scrap, iron, steel and materials from the perspective of "resource-environmental protection cycle". From the process, equipment, automation, the whole of China's iron and steel industry equipment technology has reached or reached the world advanced level; large and medium-sized steel enterprises the main body of the equipment, has reached the international advanced level, advanced construction around the world. Intelligent technology has developed rapidly. From the varieties of research and application, the quality of square steel pipe is increasingly stable; Varieties are moving towards the middle and high end. Steel as a representative of a variety of advanced steel material varieties have been achieved a breakthrough; Some steel varieties reached the international advanced level. From the perspective of environmental protection technology, the total emission of pollutants and the emission of pollutants per unit product have been greatly reduced and the environment of iron and steel enterprises has been significantly improved.

In his report to the conference, expert pointed out that the connotation of high-quality development mainly includes four aspects: First, high-quality development is an active choice to adapt to the new normal of economic development; Second, high-quality development is the fundamental embodiment of the new development concept.Third, high-quality development is the inevitable requirement to adapt to the change of the principal contradiction in our society; Fourth, high-quality development of structural steel pipe is the only way to build a modern economy.

At present, the sustainable development of China's steel industry is facing a new situation and new tasks, which are mainly reflected in the following aspects: first, China's steel industry has made remarkable achievements in energy conservation and emission reduction; Second, ultra-low emissions put forward new requirements for energy conservation and emission reduction in China's steel industry. Third, environmental protection policies and standards are becoming stricter and historical problems have become new environmental risks for Chinese steel enterprises. Fourth, "dual control of energy consumption", "control of coal" and "reduction of carbon" have more severe constraints on steel pipe suppliers. Fifth, technological innovation is still difficult to fully support the demand for green development of China's steel industry;Sixth, promoting supply-side structural reform will remain the fundamental guarantee for the green development of China's steel industry. The marks of China's high-quality steel development success include four aspects: first, leading the scientific and technological innovation of the industry; second, leading the management innovation of the industry; third, making major contributions to the formulation of global industry rules; fourth, playing a leading role in undertaking global social responsibilities.

The main factors affecting the pipe market trend

 At present, the main factor affecting steel pipe market is still the supply and demand situation of rectangular hollow section. With the trade war, the market is dominated by supply and demand fundamentals.Among them, the focus of attention is still the change of market inventory. Although the overall increment is limited, the accumulative storehouse speed of the two storehouses is accelerated. Part of the increase of the two storehouses is individual storage in winter, but it is mainly caused by weak demand, and the market's expectation of accumulative storehouse after the festival is more obvious.

 

And the environmental production limit is expected last week after the release of concentrated good has been gradually digested by the market.In the case of high profits, steel pipe suppliers are still spare no effort in the production. Production limit is becoming strict in Tangshan area and the rate of blast furnace utilization has decreased, but there are still blast furnace production phenomenon of steel mills , some steel mills are preparing to resume production. According to the NDRC's website, in November, China's crude steel output reached 77.62 million tons, up 10.8 percent year-on-year, up 8.6 percentage points.Steel production rose 11.3 per cent, compared with a 2.9 per cent drop in the same period last year. From January to November, China's crude steel output was 857.37 million tons, with a year-on-year growth rate of 6.7% and a year-on-year growth rate of 1 percentage point.Steel output was 1012.92 million tons, up 8.3 percent or 7.2 percent. That will continue in the New Year, unless profits collapse, forcing mills to cut production of structural steel pipe.

 

In terms of demand, at present, the north has entered the winter break stage, and the construction in other places is obviously affected. Although the demand resilience exists, it is generally weak, which will become more and more obvious.Therefore, from the perspective of supply and demand, the market does not have the conditions for a big market. From the analysis of winter storage policy, up to now, some steel mills such as hegang, yaxin have started to issue winter storage policy, and some regions still think the current winter storage policy is too high.But the loan is also facing cost and threshold constraints, hollow section manufacturers at the end of the financial pressure is very tight.In the case of two consecutive years of losses in winter storage, businesses dare not rush to carry out winter storage operation, and another factor is the expected global economic downturn next year. Unless there is a significant pullback in January or a significant improvement in market expectations, this trend is likely to continue.

What are the advantages of using Tianjin steel pipe in your construction projects

 Steel is a versatile building material, which has led to its inclusion in nearly every stage of the construction process from framing and floor joists, to roofing materials. Here are some of the main benefits that make structural steel such a reliable choice. At present, more and more building owners, designers, architects, and general contractors have opted for structural steel pipes in commercial construction projects over other materials mainly for its energy efficiency, low maintenance, and durability. Besides, some other key attributes, such as striking beauty, clean look, and versatility in both new and retrofit construction are becoming helpful to firmly establish steel as the material of choice for institutional, commercial and education building projects. 

Due to the great strength, uniformity, light weight, ease of use, and many other desirable properties, galvanized steel pipe has been widely used in a variety of practical purposes. There are a few advantages of using Tianjin steel pipe in your construction projects as follows: 

1. Steel frames save money.

One of the reasons that homeowners avoid steel is sticker shock. Compared to timber framing, the initial construction cost is typically more expensive. Long term, however, steel will end up saving everyone money. For you, the builder, you’ll find it cheaper to haul away scrap because it is recyclable, which means that waste removal companies often don’t charge to pick up your scrap steel. For the homeowner, the money savings come with things like maintenance and insurance. Tianjin steel pipes won’t rot, splinter or become damaged by pests, and insurance companies typically charge substantially less on homeowner’s insurance for steel frames over timber frames. 

2. Steel frame building materials are versatile.

No other building material can allow you to accomplish as much as you can with Tianjin steel pipe. Unlike timber, mild steel pipe is easy to shape, meaning that you can create all kinds of architectural interest. More importantly, however, is the fact that steel is more structurally sound than timber, which means that you can build much larger interior spaces without pillars or load-bearing walls. 

3. Tianjin steel pipe is the eco-conscious choice

There are many factors that make steel environmentally friendly. Tianjin steel pipes are recycled products, which means that any waste along with end-of-life steel building materials can be recycled.

These reasons should be enough for any builder to consider Tianjin steel frame building materials for their next project, but if you’d like to learn even more about steel building products, DongPengBoDa Steel Pipe is one of the famous steel pipe manufacturers in China. We would love for you to get in touch with us, let’s discuss your next project.

Tianjin welded steel pipe makes great progress in the steel pipe industry

 In these years, Tianjin steel pipe has played a vital role in the global steel pipe market. Especially Tianjin welded steel pipe has a large demand around the world for years. Tianjin welded steel pipe has a lot of competitive advantages such as the strength, environmental friendliness, lower insurance premiums, design flexibility as well as recyclability. Other advantages of using Tianjin welded steel pipes are involved in energy-efficiency, durability, and resistance to water, fire and insect damage. Today, Tianjin welded steel pipes have been widely used as one of the most important building materials in construction projects. 

Following the four major developments in steel pipe production, Tianjin welded steel pipe has made great improvements in protective coatings and steel pipe quality compared with other counterparts in the market. Take black steel pipe for an example. Many dielectric coatings or surface treatments are now available today. Besides, improvements in the machines for fabrication of welded steel pipe are remarkable around the world today. In the 21st century, there is a potential big demand for Tianjin welded steel pipe to be used in cost-effective transportation systems. Moreover, Tianjin durable steel pipe with longer life will be in great demand because of the too-short design life of many buried pipes now in service. For pipelines of the 21st century, Tianjin welded steel pipe makes a great effort in pipeline systems at home and abroad.

In accordance with the requirement of green development, China’s steel industry has increased inputs in capital, talent, technological research and development, and carried out valuable explorations in the new generation of recyclable processes for steel production, green manufacturing, and environmental management, etc. For example, hot dipped galvanized steel pipes generally have the rational cost effective in the current steel pipe market. Due to its durability and anti-corrosive properties, galvanized steel pipe can recycled and reused, which to some degree save a lot of money during the post maintenance work. Testing and studies have revealed that the average life expectancy for galvanized steel used as a typical structure material is well beyond 50 years in a rural environment and 20-25 years or more in an extreme urban or coastal setting. In that regard, contractors can confidently use this product in project. In the pipeline projects, Tianjin welded steel pipe, especially galvanized steel pipe has been widely used in large diameters because of thin wall and light weight. Furthermore, Tianjin welded steel pipe is versatile because of its ductility, and because of common procedures for cutting and welding. Special sections can be fabricated to meet virtually any requirement. Tianjin structural steel pipe can be provided in virtually any size and strength based on your specific requirement in applications. 

China hollow section tubes have competitive advantages in the global market

Today, China hollow section tubes have a large demand in the global steel pipe market because of a few competitive advantages. One aspect which is especially favorable for China hollow sections is the lower drag coefficients if they are exposed to wind or water forces. The internal void can be used in various ways, e.g. to increase the bearing resistance by filling with concrete or to provide fire protection. In addition, heating or ventilation systems sometimes make use of the hollow section columns. In construction projects, China hollow section tubes have many uses such as structural applications involved in residential, commercial and industrial construction. In particulars, as the flat square surface has the performance to ease construction, rectangular steel pipes are sometimes widely used for architectural aesthetics in exposed structures. 

Nowadays, welded hollow sections, also called welded steel pipe with a longitudinal weld are mainly made employing either electrical resistance welding processes or induction welding processes. Specifically speaking, a strip or plate is formed by rollers into a cylindrical shape and welded longitudinally. The edges are heated, e.g. by electrical resistance, then the rollers push the edges together, resulting in a pressure weld. The weld protrusion on the outside of the tube is trimmed immediately after welding. Square or rectangular hollow sections are sometimes made by forming a single strip to the required shape and closing it by a single weld, preferably in the middle of a face. 

In practical applications, round steel pipe and square steel pipe are often regarded as one of important building materials in the construction trade. When it comes to construction projects, steel tubes are used in many building types from small storage units to skyscrapers in big cities. For example, they are used to create the foundation of large buildings as well as other framework. Steel tubes are also used to construct balconies along with railing for staircases. As for their function with tools used for such projects, steel tubes can be seen in the scaffolding workers rely on to reach tall points of buildings. Although the manufacturing costs of hollow sections are higher than those for other sections, leading to higher unit material cost, economical applications are achieved in many fields. The application field covers all areas, e.g. architectural, civil, offshore, mechanical, chemical, aeronautical, transport, agriculture and other special fields. In construction projects, China hollow section tubes are very popular among any other structural steel pipes in use involved in residential, commercial and industrial construction. In particulars, as the flat square surface has the performance to ease construction, rectangular steel pipes are sometimes widely used for architectural aesthetics in exposed structures. 

Tianjin steel pipe development prospect in 2020

In the global steel pipe market, Tianjin steel tube has accounted for a large proportion. Every year, a number of customers around the world come to Tianjin for their desired steel products. Tianjin steel pipe play a significant role in the development of modern times today.

For a long time, Tianjin steel tube manufacturers by virtue of its very good reputation and high quality, stand out from other competitors in the global market. In order to meet customers’ requirements for low costs, steel pipe manufacturers in China try to carry out “dimensional accuracy improvements” that is aimed at the “elimination of cold-drawing” as well as the “workability improvements” that is aimed at the “elimination of heat treatment” in steel pipe manufacturing. In general, one of the causes for reduced dimensional accuracy is due to the deformation of the end of a pipe occurring with pipe circumferential forces and residual stress distribution during the production process. Especially in the recent years, Tianjin steel pipe manufacturers are committed to development new advanced technology in achieving improvements involving in low-strain pipe manufacturing, minimizing forming strain during the manufacturing process as well as workability in 2020. In future, it is believed that a seam-forming strain in a positive way will become even more important than technologies for the mere formation of shapes. 

For structural steel pipes, the efficiency of production in small lots has to be enhanced in the current steel pipe market. It is necessary to promote the use of cage rolls as a size-independent technology in the production process, or the application of flexible forming mills to medium diameter pipes. Besides, it is essential to manufacture products suited for the use in specific environments, and even to improve the technology applied to adding various working at low costs. As a result of the reduced manufacturing costs and improved quality, it is hoped that seam-welded steel pipes will enter the market for high-strength, high-grade pipes, in which seamless steel pipe have been predominant in the market.

Today, welded steel pipe has been widely used in pipeline projects for a long history. Medium-diameter seam-welded steel pipes are mostly used as line pipes in many large projects in the world. The most important target in the seam-welded steel pipe manufacturing process in relation to the line pipe and oil well pipe market is to ensure a welding quality that is capable of competing with seamless steel pipe in the market and also to establish a corrosion-resistant high-alloy steel pipe manufacturing technology in 2020. In addition, it will be necessary to establish atmospheric control technology in addition to the current method of heat input constant welding control, and also to develop a combined welding method based on present ERW in the current steel pipe market.

China hollow section tubes make great progress in manufacturing technology in 2020

From the point of view of manufacturing technology in 2020, China hollow section tubes have basic technological improvements in steel production, involving in high purity refining, process metallurgy through hot rolling, and welding control, as well as the progress that has been made in hollow section tube manufacturing technology in each area so far. 

For a long time, China hollow section tubes play an active role in the global steel pipe market, such as ASTM A500 is the most common steel specification for hollow structural section in the steel pipe market around the world. This specification is for cold formed welded and seamless carbon steel tubing in round, square and rectangular shapes. ASTM A501 is another standard for hot formed steel tubing. In the recent years, steel pipe manufacturers in China are committed to technological development in hollow section tube manufacturing. The outstanding feature is the fact that development has been pursued systematically in combination with experiments in response to rapid progress in computers in 2020. For example, China hollow section tubes have supported the progress of each industrial field by developing the supplying steel pipes at the highest technological level. For example, rectangular steel pipe has been widely used in many structural applications involving in residential, commercial and industrial construction fields in the modern. Rectangular steel pipe is fire resistant and does not warp, twist, split, swell or shrink. It resists dry rot and mildew, termites and carpenter ants. For increased fire resistance, the exterior of the product may be sprayed with a fire retardant material.

Today, China hollow section tubes keep up with the times, committed to meeting the requirements for diversified steel pipe performance, including corrosion resistance treatment by galvanizing and aluminizing in the field of structural steel pipes, as well as in civil engineering and construction. Other new aspects include optimizing the weldability according to the application, adhesion of composite steel pipes to concrete, reduction of workpiece weight and volume by high strength steel pipes, steel pipes conforming to seismic design standards, and steel pipes matching scenic conditions. However, China hollow section tube has strongly intensive labor in manufacturing, and its profits depend largely on labor saving technologies. Furthermore, production depends to a great extent on the world energy situation in addition to business fluctuations. In that regard, it is very important for China steel pipe manufacturers to optimize flexibly the operational formation in production lines. And each mill has managed to implement this in future.

How to look at Tianjin steel pipe in 2020

It would be destined to be extraordinary in 2020. Why? Since we entered into a new year of 2020, we are suffering a worldwide epidemic so far, which has made great influence both in our work and life. So does steel pipe industry. Facing such an unexpected challenge, how we look at Tianjin steel pipe in 2020?

Overall, the current worldwide epidemic really has much effect on the steel pipe production around the world. That does not mean we will have a negative attitude towards the whole steel pipe industry around the world in the coming days. On the contrary, Tianjin steel pipe keeps giving a full play to its advantages and takes advantage of the good resources to provide customers with various types of steel products in the global steel pipe market. Especially, steel pipe manufacturers in China try to carry out “dimensional accuracy improvements” that is aimed at the “elimination of cold-drawing” as well as the “workability improvements” that is aimed at the “elimination of heat treatment” in steel pipe manufacturing. Tianjin steel pipe will adjust the production structures in production and adopt advanced technology to achieve improvements involving in low-strain pipe manufacturing, minimizing forming strain during the manufacturing process as well as workability in 2020. In future, it is believed that a seam-forming strain in a positive way will become even more important than technologies for the mere formation of shapes. 

With regard to structural steel pipes, the efficiency of production in small lots has to be enhanced in the current steel pipe market. It is necessary to promote the use of cage rolls as a size-independent technology in the production process, or the application of flexible forming mills to medium diameter pipes. Besides, it is essential to manufacture products suited for the use in specific environments, and even to improve the technology applied to adding various working at low costs. Furthermore, with the complete series of steel pipe production equipment, as well as the professional and experienced personnel, cold rolled steel pipe is committed to meeting the customer's various practical application needs so far. Moreover, it does matter that Tianjin steel pipe manufacturers should have an objective and rational analysis of the current steel pipe market considering the special conditions and potential factors in the steel pipe industry, and then make reasonable production strategies to meet the needs of customers as much as possible.

The growth rate of China’s steel demand will fall in 2020

Looking forward to the Chinese steel market demand situation of structural steel pipe in the New Year, its total consumption continues to be robust, there is still room for growth after the step of 1 billion tons, but due to a variety of factors, the demand growth rate will be significantly reduced. According to preliminary estimates, China's total crude steel demand is expected to exceed 1.03 billion tons in 2020, an increase of more than 3% and at least 3 percentage points lower than the growth rate in 2019. The apparent consumption of crude steel in China is about 960 million tons, an increase of more than 4%.Crude steel exports (converted from steel exports) about 70 million tons.

In 2019, China's total demand for steel (including exports, the same below) is growing strongly, with crude steel approaching or reaching 1 billion tons.After jumping to this new level, China's steel demand volume of mild steel tube will expand. China's total crude steel demand is expected to exceed 1.03 billion tons in 2020, an increase of more than 3%. China's steel and steel demand continued to grow in the New Year, mainly driven by three forces: First, investment in fixed assets, especially infrastructure investment to "strengthen weak links", is growing rapidly. Downward pressure on the domestic and foreign economies will still exist in 2020. To this end, policy makers will strengthen counter-cyclical adjustment and focus on stimulating end consumption and "shoring up weak spots" fixed asset investment. Since 2019, relevant departments have repeatedly "cut interest rates" in a disguised way, launched large-scale issuance of ultra-long-term local government bonds, and reduced taxes and fees. At the same time, real estate investment is still running at a high level, and overseas funds are accelerating their entry. Therefore, it is expected that the growth rate of national fixed asset investment, especially the growth rate of infrastructure investment, will increase in 2020, which will generate more steel demand such as China hollow section tube.

Second, foreign trade exports are likely to improve. The rise of global trade protectionism in 2019, especially the "trade war" initiated by the US trump administration, has already harmed global trade and economic growth, including the US itself facing the risk of economic recession. In order to get out of the recession crisis, the "trade war" is likely to be temporarily suspended within a New Year. Moreover, major countries in the world have started a new round of monetary easing. While cutting interest rates, they have resumed QE one after another and coordinated with proactive fiscal policies. The federal reserve has also cut interest rates twice in a row. As a result, global economic growth of galvanized steel pipe is expected to recover in 2020.

unswervingly pursue innovative development in pipe industry

Miao changxing said that in order to achieve high-quality economic development, China must have high-quality manufacturing industry as a support. Innovation is the "cow nose" of high-quality development of manufacturing industry. He pointed out that in recent years, with the completion of the work of reducing overcapacity of mild steel tube and cracking down on "floor steel", the supply system of the steel industry has been further optimized, but there are still many problems such as weak independent innovation ability, low level of green development and low value-added products.

Miao changxing believes that only by relying on technological innovation ability to create new engines of development, foster new drivers of development and create new space for development, can the steel industry continuously improve quality and efficiency, transform and upgrade, and move to the middle and high end of the global value chain. The innovation and development of steel industry should focus on the following four aspects: First, we will strengthen the dominant position of steel pipe suppliers in technological innovation. First of all, we should improve the system and mechanism of technological research and development in the leading industries of enterprises, promote the flow and accumulation of innovative elements such as technology and talents to enterprises, and promote the improvement of technological research and development system and system construction of enterprises.

Secondly, we should establish a reasonable research investment mechanism, actively mobilize the strength of all aspects, and gradually establish a research investment mechanism with government investment as the guide, enterprise investment as the main body, and social capital as the supplement. Second, we will increase research and development of key generic technologies. With the demand of the current national economic development, suppliers should focus on solving a number of key technologies, solve the bottleneck in the development of the production of structural steel pipe. Third, we will strengthen the building of an innovative talent pool. We should establish a multi-level talent training system, focus on training leading and leading talents, and constantly improve the incentive mechanism to encourage innovation, so as to fully mobilize the enthusiasm of scientific researchers.

Fourth, we will actively develop an industrial-oriented patent layout, form a number of patent portfolios in key core technology areas, and build a reserve of intellectual property rights to support industrial development and enhance the competitiveness of enterprises. We will further cultivate ability of hollow section manufacturers to apply intellectual property rights, industrialize their innovative achievements, move up the industrial chain and cope with international disputes.

Multiple departments speed up the disposal of unqualified enterprises

The central economic work conference called for steady progress in weeding out the unqualified steel pipe manufacturers, speeding up the disposal of "zombie enterprises" and formulating exit measures. According to the work process of ministries and commissions, steel, coal and other industries are accelerating the disposal of "unqualified enterprises". Last November, for further promoting the structural reform of the supply side , some institute like the national development and reform commission, ministry of industry and information technology issued a notice to production enterprises for the disposal work. This notice further defined the disposal principle, the scope of disposal, treatment, disposal process and time, etc. In addition, the purpose of this public notice also include effectively guarding against enterprises to resolve the debt risk, boosting transfer efficiency of economic mass.

The important way to update development of the economy is steadily pushing forward the enterprise evolution. However, how to realize the evolution of hollow section manufacturers? It depends on the steel pipe market. Therefore, it is very important to create a fair competition environment and further strengthen the fundamental position of competition policy. From the current situation, it is more rely on the power of the market.

An executive director of a technology research institute said that speeding up the disposal of "zombie enterprises" has two roles. First, reduce inefficient supply, reduce overcapacity and accelerate the market clearing process. Second, they will optimize the stock of resources, increase the efficiency of resource allocation, and release a large amount of precipitated resources. These resources include tangible resources such as people, property, goods and land, as well as intangible resources such as entrepreneurship and market vitality. Of course, the short-term pain of dealing with "zombie enterprises" is inevitable. The key for China steel tube manufacturers is to stick to clear principles, use appropriate means and set rational goals. In principle, suppliers should adhere to the guidance of the government and rule of law. In terms of means, the standard of "zombie enterprises" should be defined, and different degrees of "zombie enterprises" should be classified.

The time and scope of the target should be well defined, and it is not easy to go too fast. In addition, there are many "zombie companies" in construction materials, commercial trade and real estate. In order to complete all the disposal work by the end of 2020, there is no doubt that the disposal will be intensified this year. The disposal work also include unqualified pipe production like the production of black steel pipe as raw material is very important.

Looking forward to steel pipe market in 2019 according to 2018 performance

According to the listed steel pipe companies, they announced the results that the performance of the steel pipe market in 2018 is quite excellent. The earnings of steel pipe industry ushered in a peak. Industry insiders believe that in the end of the real estate cycle, the decline in consumption of cars, appliances will continue. The steel industry has had its ups and downs in 2018.Take the local thread price in Shanghai as an example. In march, there was an extreme situation that the monthly price dropped by more than 600 yuan/ton, and then it climbed by 1200 yuan/ton and reached the high of the year in October. From the final results, steel companies still had a good year.

In 2018, the net profit attributable to shareholders of the listed company is expected to increase by 1.785 billion yuan to 2.088 billion yuan year-on-year, and increase by 67.46% to 78.91% year-on-year. Baosteel's net profit is expected to rise by 1.5 billion yuan to 2.3 billion yuan, up 8 percent to 12 percent year-on-year. Based on this data, baosteel's annual net profit for 2018 will exceed 21 billion yuan.

In 2018, the outstanding performance of hollow section manufacturers mainly lies in the good market environment provided by the supply-side reform. Under the background of tight balance, both quantity and price rise. In addition, about 50 million tons of production capacity of new iron ore will be added in 2018. The price of iron ore, the main raw material, fluctuates, making the cost side pressure of steel mills less. From the market situation, the overall performance of the steel sector in 2018 is not good. Compared with the tight balance between supply and demand for cold rolled steel pipe in 2018, the supply in 2019 will slightly increase and the growth of demand will slightly slow down, which will weaken the support for prices.

In 2019, with the downward pressure on the economy, the overall marginal performance of steel supply and demand is weaker, and the overall profits of the steel industry will narrow. In the past three years, the steel industry has reduced 150 million tons of excess capacity and removed 140 million tons of "steel". The power of the steel mill significantly enhanced. At the same time, the real estate demand for square steel pipe is still at a relatively high level, and more efforts have been made to make up for the shortage of infrastructure, so as to support the construction steel from the demand.

Tianjin welded steel pipe classification in the market

Today, Tianjin steel pipe is playing a vital role in the steel pipe industry around the world. Especially Tianjin welded steel pipe become a favor among many users from different countries in the world. Generally, Tianjin welded steel pipe can be divided into straight seam welded pipe and spiral welded pipe as per different shapes of welded steel pipe. The straight seam welded pipe undergoes much simpler processing method than the spiral welded pipe does. Furthermore, thanks to its low manufacturing costs, straight seam welded pipe wins fast development prospect. However, the strength of spiral welded pipe is generally higher than that of straight seam welded pipe because the later is made from a narrow billet production into a larger diameter welded steel pipe. As a result, straight seam welded steel pipe usually has a small diameter while the spiral welded steel pipe mostly has large diameter.

In the current steel pipe market, there are a variety of types of welded steel pipe for your choice. Sometimes, you may be confusing about how to choose the proper type of steel product in your project. Here we would like to talk about some common types of welded steel pipes in the market. One process for producing pipe is fusion weld, sometimes called “continuous weld”, which is produced in size1/8’’ to 4~12’’. Fusion weld pipe begins as coiled steel of the required width and thickness for the size and weight of pipe to be made. Successive coils of steel are welded end to end to form a continuous ribbon of steel. The ribbon of steel is fed into a leveler and then into a gas furnace where it is heated to the required temperature for forming and fusing. The forming rolls at the end of the furnace shape the heated skelp into an oval. The edges of the skelp are then firmly pressed together by rolls to obtain a forged weld. The heat of the skelp, combined with the pressure exerted by the rolls, form the weld. No metal is added into the operation. Final sizing rolls bring the pipe into its required dimensions. In the recent years, China hollow section tube manufacturers are committed to providing customized welded steel pipes for users around the world.


Another common type of welded steel pipe in the market is ERW pipe. The processing of electric resistance welded pipe begins as a coiled plate of steel with appropriate thickness and specific width to form a pipe that conforms to its relevant specifications. ERW pipe is cold formed. For example, cold rolled steel pipe is very popular in a variety of applications in the recent years. The ribbon is pulled through a series of rollers that gradually form it into a cylindrical tube. As the edges of the now cylindrical plate come together, an electric charge is applied at the proper points to heat the edges so they can be welded together.

China hollow section tubes are popular in structure applications today

As we all know, the excellent properties of the tubular shape have been recognized for a long time. In the first part of the previous century, an Englishman, Whitehouse, developed the fire welding of circular hollow sections. However, the production of welded circular hollow sections became more important after the development of the continuous welding process in 1930 by the American, Fretz Moon. In the recent years, the first production methods for seamless and welded steel pipe have made great progress in the steel pipe industry.

Technically speaking, design is an interactive process between the functional and architectural requirements and the strength and fabrication aspects. In a good design, all these aspects have to be considered in a balanced way. Due to the special features of hollow sections and their joints, it seems even of more importance than for steel structures of open sections. Therefore, it is very important for you to choose the proper type of structural steel pipe in construction projects. In these years, China hollow section tubes play a significant role in the global steel pipe market. China hollow section tubes as an important building material used in the construction industry tend to serve a wide range of functions often, due to the good performances of durability, strength and resistance to harsh environment conditions. In the current steel pipe market, round steel pipe and square steel pipe are the popular building materials in construction. With steel, it's easy to expose the building's beauty in a design that will emphasize its grace, strength, transparency, and slenderness. The column-free clear spans and the use of colored steel pipe coatings bring out the natural lighting of the frame and its simple elegance. In construction projects, China hollow section tubes have many uses such as structural applications involved in residential, commercial and industrial construction. In particulars, as the flat square surface has the performance to ease construction, rectangular steel pipes are sometimes widely used for architectural aesthetics in exposed structures.

In the current steel pipe market, hot dipped galvanized steel pipe are very popular among builders. Many examples in nature show the excellent properties of the tubular shape with regard to loading in compression, torsion and bending in all directions. And these excellent properties are combined with an attractive shape for architectural applications. Furthermore, the closed shape without sharp corners reduces the area to be protected and extends the corrosion protection life in applications.

We will consolidate efforts to cut overcapacity in steel

At present, China's steel industry has basically built a standard system including basic general standards, product standards of China hollow section, method standards and management standards, but there are also some shortcomings. Lv guixin, inspector of the raw material industry department of the ministry of industry and information technology, said recently that in the process of consolidating the achievements in steel cutting capacity, we should give full play to the role of "hard constraints" on standards. On November 9, the "2019(first) China steel high quality development standardization forum" hosted by the metallurgical industry planning and research institute was held in Beijing. Lu guixin, inspector of the raw material industry department of the ministry of industry and information technology, pointed out at the meeting that in the process of consolidating the achievements in steel cutting capacity, we should give full play to the role of "hard constraints" on standards, and implement laws, regulations and mandatory standards on environmental protection, energy consumption, quality, safety and technology.

He stressed that "steel pipe suppliers that fail to meet the standards shall be rectified within a time limit and those that still fail to meet the standards after rectification shall be resolutely cleared." At present, China's steel industry is in a critical period of transformation and upgrading, doing a good job of standardization is of great significance. Planning institute director said the advanced standard system construction of iron and steel industry can promote the product quality and technological progress, industrial upgrading. It is reported that China's steel industry has basically built including basic general standards, product standards, methods standards and management standards. At the same time, the steel industry standardization work also has some deficiencies. For example, the existing standard system needs to be strengthened in adapting to, promoting and leading industrial transformation and upgrading.The advanced nature and foresight of the standard of hot dipped galvanized rectangular steel tubes are not enough, the revision and formulation cycle is longer, and the lack and lag of the standard still exist.

"To accelerate the transformation and upgrading of the steel industry, we should take the opportunity of comprehensively deepening the standardization reform, constantly improve and upgrade the standard system, and lead the high-quality development of China's steel industry by standards. We should rely on market-based and law-based approaches to cutting overcapacity of mild steel tube, which means relying on laws, regulations and mandatory standards on environmental protection, energy consumption, quality, safety and technology.

The steel industry has undergone a structural adjustment

China has cut steel production capacity of China hollow section tube by more than 150 million tons since 2016, 114% of the global total, according to 21st century business herald.To this end, China has relocated 280,000 steel workers alone, more than the total number of steel jobs in the US, Europe and Japan. At present, China's steel market conditions have improved significantly;capacity utilization rate of  crude steel has returned to more than 80% of the reasonable range. The capacity has entered the deep water now; the steel industry transformation and upgrading difficulties are also increasing. Since last year, due to the favorable market situation of the steel industry, driven by high profits, some regions and enterprises have become more willing to invest in the steel industry, and the implementation of capacity replacement in some regions is out of shape, and the impulse to increase production has increased significantly.

After more than three years of cutting capacity of mild steel tube, the steel industry is now entering a stage of structural adjustment. The means of administrative regulation is gradually weakening, mainly through the market demand by limit production enterprises, but this year the continuous pessimistic will lead to the iron and steel industry of real estate profits further narrowed. Under the pressure of deleveraging of domestic real estate enterprises, operating income and net profit of a number of listed steel enterprises in the third quarter fell to different degrees and they will continue to bear some pressure in the short term. On Oct. 28, chongqing iron and steel released its third quarter 2019 report, showing that its operating revenue in the first three quarters was 17.284 billion yuan, down 0.87 percent from the same period last year. Net profit attributable to shareholders of listed companies was 720 million yuan, down 51.36% from the same period last year.

Chongqing steel pipe suppliers explained that the decline was mainly due to a 4.4 percent year-on-year drop in the composite sales price of steel, reducing profits by 759 million yuan. The price of ores, coal, alloys, scrap and other raw fuels increased, reducing profits by 824 million yuan; Steel sales volume increased by 4.41% year on year, increasing profit by 100 million yuan; The reduction of process costs and the reduction of expenses added 724 million yuan. In addition, steel giant baosteel's previously disclosed third quarter report showed that baosteel's operating revenue in the first three quarters of this year totaled 216.876 billion yuan, down 3.75% year on year. Net profit was 8.874 billion yuan, down 43.65% year on year; Net cash flow of structural steel pipe from operating activities was 19.595 billion yuan, down 46.68% year on year.

Accelerating the establishment of a water quota system for the pipe industry

China is a big steel country. The water consumption in the steel industry accounts for more than 10% of the industrial water consumption, ranking the third in the industrial industry and belonging to the high water consumption industry. In 2002, the state promulgated the national standard of "water intake quota, part 2, hollow section manufacturers", which was revised times in 2012. The promulgation of water intake quota has greatly promoted the progress of water-saving technology in the steel industry. Technological measures such as technology water-saving, recycling water and waste-water reuse have been adopted comprehensively, and the water consumption index has been steadily improved. Water withdrawal per ton of steel decreased from 8.71 cubic meters in 2005 to 3.12 cubic meters in 2017, and water reuse rate increased from 94.3 percent in 2005 to 97.83 percent in 2017.

However, the standard work of water quota is still lagging behind, especially for industrial water quota, there are many problems such as vague concept, non-standard method, imperfect system, which cannot adapt to the new situation of water resource management. In accordance with the requirements of strict water resources management and water efficiency management innovation system, it is necessary to strengthen the in-depth study of the relevant standard system. In order to better promote the water-saving work of steel pipe suppliers, it is necessary to establish a perfect water quota standard system for steel industry.

1.The water quota standard system for the steel industry is an effective measure to support the national water-saving action. The state implements strict water resources management and assessment system. The steel industry is a high water consumption industry, so it is necessary to establish a water-saving assessment system corresponding to this. 2. The steel industry water quota standard system provides the direction for the water-saving work of steel enterprises.In the case of extensive water use in China's steel industry of rectangular hollow section, China has implemented the water intake quota for steel joint enterprises for nearly 20 years, which plays an important role in promoting water saving and water efficiency in steel enterprises. However, as the iron and steel industry to raise the level of water-saving water, limitations of water-saving management becomes more and more obvious, which can't adapt to the demand of steel water completely, and steel enterprise production process and product water quota, need to increase the constraint conditions, from the aspects of process and product water leading the all-round fine iron and mild steel tube manufacturers carry out the water-saving work.

Tianjin steel pipe development prospect in 2020

In the global steel pipe market, Tianjin steel tube has accounted for a large proportion. Every year, a number of customers around the world come to Tianjin for their desired steel products. Tianjin steel pipe play a significant role in the development of modern times today.

For a long time, Tianjin steel tube manufacturers by virtue of its very good reputation and high quality, stand out from other competitors in the global market. In order to meet customers’ requirements for low costs, steel pipe manufacturers in China try to carry out “dimensional accuracy improvements” that is aimed at the “elimination of cold-drawing” as well as the “workability improvements” that is aimed at the “elimination of heat treatment” in steel pipe manufacturing. In general, one of the causes for reduced dimensional accuracy is due to the deformation of the end of a pipe occurring with pipe circumferential forces and residual stress distribution during the production process. Especially in the recent years, Tianjin steel pipe manufacturers are committed to development new advanced technology in achieving improvements involving in low-strain pipe manufacturing, minimizing forming strain during the manufacturing process as well as workability in 2020. In future, it is believed that a seam-forming strain in a positive way will become even more important than technologies for the mere formation of shapes.

For structural steel pipes, the efficiency of production in small lots has to be enhanced in the current steel pipe market. It is necessary to promote the use of cage rolls as a size-independent technology in the production process, or the application of flexible forming mills to medium diameter pipes. Besides, it is essential to manufacture products suited for the use in specific environments, and even to improve the technology applied to adding various working at low costs. As a result of the reduced manufacturing costs and improved quality, it is hoped that seam-welded steel pipes will enter the market for high-strength, high-grade pipes, in which seamless steel pipe have been predominant in the market.

Today, welded steel pipe has been widely used in pipeline projects for a long history. Medium-diameter seam-welded steel pipes are mostly used as line pipes in many large projects in the world. The most important target in the seam-welded steel pipe manufacturing process in relation to the line pipe and oil well pipe market is to ensure a welding quality that is capable of competing with seamless steel pipe in the market and also to establish a corrosion-resistant high-alloy steel pipe manufacturing technology in 2020. In addition, it will be necessary to establish atmospheric control technology in addition to the current method of heat input constant welding control, and also to develop a combined welding method based on present ERW in the current steel pipe market.

How to manufacture hollow section tubes in a mill

In the modern times, hollow section tubes are very popular and widely used as structural materials in some large construction projects around the world. Especially in the recent years, China hollow section tubes have a great demand in the global steel pipe market due to their competitive advantages. Every year, a lot of customers around the world come to China for their desired steel products. However, whether you have tried to learn about how to manufacture hollow section tubes in a mill?

Generally speaking, hollow sections have two major categories in the current steel pipe market: seamless steel pipe and welded steel pipe. Both of them are widely used in a wide range of applications in our society today. Seamless hollow sections are made in two phases, i.e. the first phase consists of piercing an ingot and the second step considers the elongation of this hollow bloom into a finished circular hollow section. And then, the tube will go through a sizing mill to give it the required diameter. Nowadays, welded hollow sections with a longitudinal weld are mainly made employing either electrical resistance welding processes or induction welding processes. As a rule, a strip or plate is formed by rollers into a cylindrical shape and welded longitudinally. The edges are heated, e.g. by electrical resistance, then the roller push the edges together, resulting in a pressure weld. The weld protrusion on the outside of the tube is trimmed immediately after welding.

Rectangular hollow sections also called rectangular steel pipes in the current steel pipe market, which are made by deforming circular hollow sections through forming rollers. And this forming process will be done by hot or cold, using either seamless or longitudinally welded circular hollow sections. Although it is common practice to use longitudinally welded hollow section, for the very thick sections, seamless sections may be used. In addition, square or rectangular hollow sections are sometimes made by forming a single strip to the required shape and closing it by a single weld, preferably in the middle of a face. And some large circular hollow sections are also made by rolling plates through a so-called U-O press process in a mill. After forming the plates to the required shape, the longitudinal weld is made by a submerged arc welding process. Another process for large hollow section tubes for steel pipe manufacturers in China is to use a continuous wide strip, which is fed into a forming machine at an angle to form a spirally formed circular cylinder. The edges of the strip will be welded together by a submerged arc welding process to produce spirally welded tube in a mill.

China hollow section tubes make great progress in manufacturing technology in 2020

From the point of view of manufacturing technology in 2020, China hollow section tubes have basic technological improvements in steel production, involving in high purity refining, process metallurgy through hot rolling, and welding control, as well as the progress that has been made in hollow section tube manufacturing technology in each area so far.

For a long time, China hollow section tubes play an active role in the global steel pipe market, such as ASTM A500 is the most common steel specification for hollow structural section in the steel pipe market around the world. This specification is for cold formed welded and seamless carbon steel tubing in round, square and rectangular shapes. ASTM A501 is another standard for hot formed steel tubing. In the recent years, steel pipe manufacturers in China are committed to technological development in hollow section tube manufacturing. The outstanding feature is the fact that development has been pursued systematically in combination with experiments in response to rapid progress in computers in 2020. For example, China hollow section tubes have supported the progress of each industrial field by developing the supplying steel pipes at the highest technological level. For example, rectangular steel pipe has been widely used in many structural applications involving in residential, commercial and industrial construction fields in the modern. Rectangular steel pipe is fire resistant and does not warp, twist, split, swell or shrink. It resists dry rot and mildew, termites and carpenter ants. For increased fire resistance, the exterior of the product may be sprayed with a fire retardant material.

Today, China hollow section tubes keep up with the times, committed to meeting the requirements for diversified steel pipe performance, including corrosion resistance treatment by galvanizing and aluminizing in the field of structural steel pipes, as well as in civil engineering and construction. Other new aspects include optimizing the weldability according to the application, adhesion of composite steel pipes to concrete, reduction of workpiece weight and volume by high strength steel pipes, steel pipes conforming to seismic design standards, and steel pipes matching scenic conditions. However, China hollow section tube has strongly intensive labor in manufacturing, and its profits depend largely on labor saving technologies. Furthermore, production depends to a great extent on the world energy situation in addition to business fluctuations. In that regard, it is very important for China steel pipe manufacturers to optimize flexibly the operational formation in production lines. And each mill has managed to implement this in future.

In the global steel pipe market, it is common for users to speak about Hollow Structural Sections (HSS) in Canada and the USA, whereas in Europe the term of Structural Hollow Sections (SHS) is often used. In construction projects, steel structural design is an interactive process between the functional and architectural requirements and the strength and fabrication aspects. China hollow section tubes have the excellent properties with regard to loading in compression, torsion and bending in all directions. At the same time, these excellent properties are combined with an attractive shape for architectural applications in the modern times. For example, round steel pipe is favorable for structural materials in applications due to the lower drag coefficients if it is exposed to wind or water forces in pipeline projects. The internal void can be used in various ways, e.g. to increase the bearing resistance by filling with concrete or to provide fire protection. In addition, heating or ventilation systems sometimes make use of the hollow section columns.

Today, China hollow section tubes have become one of the most preferred superior construction material widely used in construction field around the world over the years. As a rule, each project is judged on its use of structural steel pipe from both an architectural and structural engineering perspective. Although the manufacturing costs of hollow sections are higher than those for other sections in the market, leading to higher unit material cost, economical applications are achieved in many fields. The application field involves in all areas, e.g. architectural, civil, offshore, mechanical, chemical, aeronautical, transport, agriculture and other special fields. In the recent years, China steel pipe manufacturers are committed to supplying more customized hollow section tubes with competitive steel pipe price in the market according to your personal preference.
