Tianjin galvanized steel pipe in 2019

Tianjin galvanized steel pipe has much more popularity in the steel pipe market around the world for years. Nowadays, Tianjin galvanized steel tube has accounted for a large proportion of the domestic market. Every year, more than half of the country's galvanized steel pipes are from Tianjin. Tianjin steel pipe manufacturers by virtue of its very good reputation and high quality, stand out from other competitors across the country today.

Welded steel pipe is the most common and widely used material in the steel market today. This kind of steel pipe can meet the actual needs from all works of life by virtue of its own good performance. As most insiders know, steel pipe pricing is mainly up to the specific purposes in the practical production activities. In other words, steel pipe price is significantly different per as different pipe sizes. It can not be denied that there are various complex factors affecting the steel pipe pricing. Therefore, it is strongly suggested that customers in the actual purchase try to make a comprehensive assessment, rather than limit themselves to the product prices. As a result, it will have not so good influence on the product application effect.

Tianjin 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. At present, more and more building owners, designers, architects, and general contractors have opted for galvanized steel pipe 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.

In the modern times, structural steel pipe is widely used as a kind of building materials, for it will remain stable and standing for longer. Another reason that steel is such a good material for building is that it is immune to infestations of termites and other pests, so the internal structure of the building is always solid. In addition, steel is considered the cheapest and most effective way of making a fire proof home. Steel is resistant to a number of forces including most extreme weather such as fire and wind and also against chemicals, whether they are toxic or not. What’s more, as steel is recycled and doesn't lose any of its great properties, it's still just as strong and durable, it remains just as resistant to extremes as when it is brand new.

ERW steel pipe

There are various types of steel pipes for your choice in the current steel pipe market today. In the practical purchase, some people may be wondering about ERW steel pipe. First of all, in order to better know the ERW steel pipe, we would like to start at the beginning of its simple definition. ERW is short for electric resistance welding. Technically speaking, the electric resistance welded processing begins with a coiled steel plate with appropriate thickness and specific width to form a pipe that conforms to its required steel pipe sizes. And ERW pipe typically holds much tighter tolerances and maintains much more consistency of surface & wall than seamless carbon steel pipe. Common ERW specs include API5LB, A53, and A500. Furthermore, ERW pipe is a high speed production product in that it can be made into continuous lengths up to 115 feet. In addition, this type of pipe has the uniform wall thickness and outside dimension with a wide range of specifications.

Seamless pipe and welded pipe are two common type of hollow structural section in use. In the current steel market, besides the ordinary types of hollow sections, such as circular, square and rectangular hollow sections, some other shapes are also available for certain applications in life. Today, some steel pipe manufacturers are committed to 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. Today, China hollow section tubes 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. Meanwhile, this better protection increases the protection period of coatings against corrosion.

In the recent years, ERW pipes are extensively used as structural steel pipes in many sectors, including agriculture, industry and construction activities such as scaffolding and casing in bore wells. They are also widely used for conveying water, gas, crude oil and etc. ERW pipes are typically used to make beams for structural framework, or for highway construction and bridges. Nevertheless, in a long run, this type of pipe will still confront a great challenge to meet very high standards of both national and international specifications in steel pipe market in future.

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 choose the proper type of galvanized steel pipe in your project

Technically speaking, galvanized steel pipe is a type of steel pipe that has been coated with zinc. This coating protects the steel from corrosion. It is most commonly used for outdoor construction like fences and handrails, or for some interior plumbing. It is also sometimes called galvanized iron pipe.

China hollow section tubes are very popular among users today. Seamless pipe and welded pipe are two common type of hollow structural section in use. Tianjin gi square steel pipe is used widely as 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 in the society. Because of years of production and processing experience, today's Tianjin gi square steel pipe production technology has got more improved and matured. Besides, with the complete steel pipe production equipment, as well as the professional and experienced personnel, Tianjin steel pipe production is committed to meeting the customer's various practical application needs.

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. As a rule, with different processing technology, there will be different product costs. That can be clearly reflected in the different pipe pricing of the two kinds of pipes. Due to the high costs, hot dipped galvanized steel pipe price is more expensive than other common types of steel pipes in the current steel pipe market.

Pre galvanized steel pipe is another popular type of galvanized steel pipe in the market today, which was galvanized while in sheet format, thus prior to further manufacturing. Pre-galvanization is also known as mill galvanized, due to the fact that the steel sheet is rolled through molten zinc. After the sheet is sent through the mill to be galvanized it is cut to size and recoiled. A specific thickness is applied to the entire sheet, for example pre-galvanized Z275 steel has a 275g per square meter zinc coating. One of the advantages which pre-galvanized steel has over hot dip galvanized steel is that it has a better appearance.

Tianjin black steel pipes have made great improvement today

In recent years, despite the overall slowdown, it requires much more improvement in the level of technology in the steel market. It is obvious that in present steel pipe market, a variety of kinds of steel pipe are widely used as structural steel pipes in construction applications. As for the modern techniques of black steel pipe, scientific advancement has greatly improved after the butt-weld method invented by Whitehouse. Today, with modern automatic machines, it has become possible to produce black steel pipes under the extremely high temperature and pressure. What’s more, it will somewhat facilitate steel pipe suppliers to satisfy different diameter requirements for customers.
In recent years, with the implementation of the national strategy “go out” and the international economic globalization, Tianjin black steel pipe is actively engaging in the international market and has played a very significant role in international business trade. Black steel pipe’s tensile strength makes it a better choice for people to convey water and gas in rural and urban areas. Besides, steel conduits can also be used to protect electrical wiring and deliver high pressure steam and air. The oil and petroleum industries widely use black steel pipe for convey large quantities of oil through remote areas. Although it doesn’t have a corrosion resistant layer like the galvanized steel pipes or other welded steel pipes, Tianjin black steel pipe plays an important role in fire sprinkler system.

Generally speaking, black steel pipe can be considered non-galvanized steel pipe compared with galvanized one. During the production of the black steel pipe, there will be kind of black oxide substance formed on its surface, which is one reason that people are used to name it black steel pipe. However, the black oxide substance has no capacity of anticorrosion and antirust. In other words, it is necessary to take some measures to protect the black steel pipe from rusting in daily applications. Technically, there are four common methods used to control corrosion on pipelines, such as protective coatings, cathodic protection, materials selection and inhibitors. Coatings and linings are principal tools for defending against corrosion. They are often applied in conjunction with cathodic protection systems to provide the most cost-effective protection for pipelines.

By and large, China's steel pipe downstream industry market demand is still growing, but the growth rate slows down. China's steel production capacity mainly depends on the demands of other industries. As a result, annual steel production capacity can roughly reflect the actual demand of the market. In that regard, Tianjin China hollow section tube manufacturers should try to make a careful analysis of the existing pipe market at first before production, and then make a clear product positioning.

Tianjin steel pipe foreground in 2019

Adjacent to Hebei Province, the largest heavy industrial base in the north of China, Tianjin steel pipe has a great advantage of material resources and human resources in the north of China. Relying on the integration of Beijing-Tianjin-Hebei regions, production personnel from high-tech R & D personnel to processing workers can both fully give full play to their own production potential in the production. Besides, the convenient transportation is also a major advantage in the development of Tianjin pipe. In short, all these can somewhat greatly reduce Tianjin pipe production costs to facilitate the competitive steel pipe prices for customers, in order to grasp more development opportunities in the fierce competition both in the domestic and international market.
Tianjin pre galvanized piping suppliers can be regarded as a little steel pipe kingdom. If only by virtue of the individual's ability to have a further development, it seems hardly to give full play to the potential development capacity in the long term. Therefore, it is considered as a long-term goal for all pre galvanized piping suppliers to provide customers with good quality pre galvanized steel pipe in the market. Regarding the production structure optimization, it means that pre galvanized piping suppliers can not only be limited to the traditional production pattern in 2019. Today, along with the tide of economic globalization development, Tianjin Pipe always keeps trying to follow the pace of the development of the times, with a positive attitude into the melting pot of the world’s economic development.

In Tianjin, China hollow section manufacturers enjoy a lot of national incentive policy advantages in the development of the international trade business. For example, the export tariff rebate for hot dipped galvanized pipe, the corporation tax relief and some other preferential policies are all very beneficial to the domestic enterprises to make further progress in the international market. And that helps enterprises to open the international market quickly in the long run. In this regard, this can be regarded as one of the important reasons for the faster development of Tianjin pipe in the international market than in other parts of the country in 2019. Furthermore, Tianjin steel pipe development has always been a model of peer attention, because of its rich resources and its mature development of various types of steel pipes in the market. It is believed that the successful development of Tianjin steel pipe has always been the prime example to other domestic steel pipe manufacturers in 2019.
