Generally speaking, black steel pipe is a type of welded steel pipe. Compared with its galvanized counterpart, there are some differences between them. Both types are made from steel and needless to say, their improvement is related with the development of crude steel production. The price of steel pipe would drop due to the high production. But one the other hand, the huge demand could help to make the price stable.

According to the national authoritative data, the daily output of crude steel is 2180,7000 tons in September. It is estimated that the quarter-on-quarter growth has accelerated to 1.99 percent. All types of steel pipes are made from steel billets. The types are separated into furnace welded pipe, electrically welded pipe and electrically arc welded pipe depending on the welding technique. And according to the different welding forms, the pipes are divided into longitudinal welded pipe and helical weld pipe. In addition, based on the shape, the pipes are separated into rounded welded pipe and other types. With the increasing capacity of steel, the welded steel pipe would usher in new development.

During series of national projects, the welded steel pipes are broadly used. For instance, the China and Myanmar natural gas line is formed by the steel pipes. To build this project, both China and Myanmar have made lots of contribution. It costs three years and millions of dollars. This project has been completed in October. And since then, Yunnan and Guizhou have ended a historic problem - they could finally use the natural gases. This project can improve the adjustment of industrial structure in these areas.

Needless to say, the quality of steel pipes must be tested to meet the demand of national project. The advanced melted technology can improve the quality of steel. Due to the various requirements, steel pipe manufacturers provide pipe designed with various diameters. The thickness has a significant influence to the strength. When you are trying to pick the right pipe, you need to determine whether the pipe could bear the desired pressure.
