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.
