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.

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. 

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.

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.

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.

Various types of Tianjin steel pipes for your choice in the market

In the recent years, Tianjin structural steel pipe has the complete steel market in the steel industry, which greatly meets the application needs of different customers.

In most common purchase, some customers often question about the differences between hot rolled steel pipes and cold rolled steel pipes. As we all know, different types of steel will undergo a wide range of processes to achieve the proper physical properties. In general, there are some fundamental differences between these two types of metal, because of their different processing methods at the mill, but not simply the product specification or grade. Theoretically, the only difference between hot rolled and cold rolled steels is that hot rolled steel is rolled to its final dimensions when it is hot enough to scale (over about  1700℉) while cold rolled steel is rolled to its final dimensions well below scaling temperatures. When steel is above the recrystallization temperature, it can be shaped and formed easily, and the steel can be made in much larger sizes. Hot rolled steel is typically cheaper than cold rolled steel due to the fact that it is often manufactured without any delays in the process, and therefore the reheating of the steel is not required (as it is with cold rolled).

China hollow section tubes are friendly environment in your projects

In construction projects, China hollow section tubes have many uses in structural applications involved in residential, commercial and industrial construction. For example, China hollow section tubes are widely used in greenhouse frame projects because of its cost effective, maintenance-free corrosion protection system that will be able to last for decades even in the harshest environments.

In the recent years, China steel pipe manufacturers are committed to providing customized shapes as per the specific requirements of clients in the world. For example, the elliptical hollow sections have become more popular for architectural designs. Of course, you can often find that some other shapes of hollow structural sections have been used in a variety of infrastructure construction around us. In the current steel pipe market, galvanized steel pipes are widely used in greenhouse frame projects because of its cost effective, maintenance-free corrosion protection system that will be able to last for decades even in the harshest environments. No additional preparation of the surface is required, no time-consuming inspections, additional painting or coatings are needed. Once the structure is assembled, contractors can immediately begin the next stage of construction without having to worry about the galvanized steel materials. Besides, due to its durability and anti-corrosive properties, galvanized steel pipes can be recycled and reused, which to some degree save a lot of money during the post maintenance work.

Tianjin steel pipe have great improvement in the steel industry. Tianjin rectangular steel pipe is one common type of hollow section tubes in the current steel pipe market, which is generally made by rolling plates to the required shape in a mill. And the longitudinal weld is made by a submerged arc welding process. In construction projects, rectangular steel pipes are sometimes preferred for architectural aesthetics in exposed structures in construction field due to its flat square surfaces. Tianjin rectangular hollow sections are cold formed and welded from either hot rolled, cold rolled, pre-galvanized or stainless steel. 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. If you would like to use Tianjin rectangular steel pipe in your project, it would be an excellent choice for bear resistant and consistent, which 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. The interior can be filled with concrete.

In this sense, Tianjin steel pipe manufacturers are supposed to try to make continuous progress in many aspects so as to provide customers with more reliable galvanized steel pipes and further obtain the product acceptance from customers in the long run. Furthermore, considering various differences between Chinese and Western worlds from different aspects, it has become a potential challenge for domestic steel pipe manufacturers to have the successful communication in the foreign trade. And also, Tianjin welded steel tube has not only excellent quality assurance, and also a relatively complete range of specifications, which can basically meet the needs of all walks of life for the practical application purposes.

As it is well acknowledged, the concentration advantage of Tianjin steel pipe manufacturers can be considered an important invisible resource, which is reflected in the high quality products with competitive steel pipe prices and considerate service. Hence, China steel pipe manufacturers should learn to make full use of the advantage and give full play to their potential ability to increase the opportunity to attract potential customers in the steel pipe market. 

Be careful for selecting your welded steel pipe in projects

Welded steel pipe is always the best favor in a variety of projects today. As is known to all, different welded steel pipe specifications are closely related to their practical application requirements. From the shape of welded pipe, it can be divided into two categories: longitudinal welded pipe and spiral welded pipe. On the one hand, by comparison between these two types of pipes, welded steel pipe obviously has a wider range of applications than spiral welded pipe. On the other hand, with the high requirements of the raw materials and processing technology, spiral welded pipe has the better performance than longitudinal welded pipe in certain applications. In addition, according to different welding forms, welded pipe can be divided into automatic submerged arc welded steel pipe and high frequency welded steel pipe. In the actual purchase, customers should have enough command of the desired products so as to select the proper products in the end.

Hot dipped galvanized steel pipe has been considered popular a lot among many users today. For one thing, the galvanization process protects the steel from rusting damage that can occur during transportation, installation and service. The zinc layer on the surface of pipe can form a barrier protection for steel products to extend the service life in applications. For the other thing, this layer is also resistant to wear and scratch, which makes the steel look more attractive. 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.

Mild steel is available in a variety of structural shapes that are easily welded into pipe or tube and etc. Today, mild steel pipe has been used for most of the pipelines in the world, for it is not only be easily welded into place flexibly but also can somewhat avoid cracking and breaking under pressure. Furthermore, most of round steel pipes and tube are easy to fabricate, readily available, and cost less than most other metals. In well protected environments, the life expectancy of mild steel pipe is 50 to 100 years. Unlike high-carbon steel pipe, mild steel pipe has carbon contents of less than 0.18%, so this type of pipe is easily welded while some types of high-carbon steel pipe, such as stainless steel pipe, which requires special techniques in order to properly weld the material.

In recent years, China hollow section tubes play an active role in the steel pipe market. Every year, lots of customers from different countries come to Tianjin to seek for their desired steel pipes. Today, China hollow section tubes also offer advantages of corrosion protection in applications. Some hollow sections have rounded corners resulting in a better protection than that with sharp corners. This is especially true for the joints in circular hollow sections where there is a smooth transition from one section to another.

Tianjin rectangular hollow sections

Today, China hollow section tubes have a potential great demand in the international steel pipe market. Especially Tianjin rectangular hollow sections have been widely used in a variety of applications, such as structural applications in residential, commercial as well as industrial construction. Besides, as the flat square surfaces of rectangular hollow sections have the ability to ease construction, they are sometimes preferred for architectural aesthetics in exposed structures. Today, Tianjin rectangular hollow sections have also become very popular in many forms of construction and other structural & mechanical applications.

Tianjin rectangular hollow sections are widely used as structural steel pipes in more and more construction projects in the modern times because this type of steel pipe are high tensile property, flexible, e.g, can be designed and fabricated to any height and strength, are easy to install, possess structural reliability, easy to maintain and are corrosion resistant. Galvanized pipe is usually used as one common type of industrial steel pipe, which has been coated with a layer of zinc. Galvanized pipes offer increased protection against corrosion. Furthermore, galvanization is often less expensive than other types of corrosion protection, which make galvanized pipes more cost effective.

In the current steel pipe market, rectangular steel pipe, round steel pipe and square steel pipe are the three major members of the hollow structural sections which are metal profiles with square or rectangular tube section. Rectangular hollow sections are cold formed and welded from either hot rolled, cold rolled, pre-galvanized or stainless steel. ASTM A500 is the most common steel specification for hollow structural section in the current 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.

As a rule, a structural steel shape is a profile, formed with a specific cross section and following certain standards for chemical composition and mechanical properties. Structural steel shapes, sizes, composition, strengths, storage practices, etc., are regulated by standards in most industrialized countries. Tianjin rectangular steel pipe has good quality and competitive price in the world due to its distinctive features and local advantages in the development for many years. Tianjin steel pipe manufacturers always try to make full use of all kinds of rich resources, as well as to combine with their own advantages so as to give full play to production activities.

How to look at galvanized steel pipe used for frame scaffolding

Generally speaking, frame scaffolding is one of the most common types of scaffolding, often seen on construction sites worldwide. Typically the frame scaffolding is manufactured from round steel tube, available in several different configurations, from a section that contains both a ladder and a walk-through portal to sections that are totally walk-through and sections that resemble a ladder. The typical method of constructing frame scaffolding is to use two sections of the scaffold frame connected by two crossed sections of support poles arranged in a square configuration.

Galvanized steel pipe generally has the rational cost effective in the market. Compared with other typical steel pipe coatings, such as specialized painting and powder coating, galvanization is much more labor-intensive, resulting in a higher initial cost for contractors. Besides, 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. If you choose a galvanized pipe, you can avoid the cost of maintaining and replacing corroded pipes. With galvanized pipe, your pipes can last a lot longer than a non galvanized one, which will save you a lot of money in the project.

Unlike other structural steel materials, galvanized steel is immediately ready for use when it is delivered. No additional preparation of the surface is required, no time-consuming inspections, additional painting or coatings are needed. Once the structure is assembled, contractors can immediately begin the next stage of construction without having to worry about the galvanized steel materials. In the majority of cases, China hollow section tube are widely used for frame scaffolding is in good condition and erected properly, it will provide a stable elevated work platform at virtually any height so that workers can easily and safely work anytime.

Today, there are many different types of scaffolding in construction. Compared with other typical steel pipe coatings, such as specialized painting and powder coating, galvanization is much more labor-intensive, resulting in a higher initial cost for contractors. Besides, 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. Hot dipped galvanized pipe has been considered popular a lot among many users today. With the layer of protection, this kind of steel pipes can be used in outdoor areas, and can withstand the harm from some of the environmental effects, which are especially used in construction today.

Spiral steel pipe manufacturing process

Generally speaking, spiral steel pipes in one type of welded steel pipe in the pipe market, which are made by steel coil, extrusion forming under the normal temperature, and then undertake the manufacturing technology of double wire and double-faced submerged-arc welded in a mill. In the past, due to the method of manufacture, Spiral Welded pipe was relegated to low pressure and structural applications. With the development of the Submerged Arc Welding process, the production of large hot rolled coils of sufficient width and the development of dependable non-destructive testing methods, it is now possible to produce Spiral Weld pipe for high-pressure service.
