ERW Pipe
ERW pipemeans electric resistance welded pipe, and it is a resistance welding by 10-500 kHz of high-frequency current.
The raw material of the ERW steel pipe is hot rolled steel coil made of steel billet, and the usual material is Q195, Q215, Q235, Q355 in China ERW pipe grade, which are same material with S195, S235, S355 in Europe, and SS400 in Japan. ERW steel pipes manufacturerswill cut the steel coil into strips first, the strip width is according to the perimeter of the pipes and then shaped by mold, welding, cutting, straightening, inspecting, end smoothing, packing, and final storage or dispatch.
The pipes are used widely in construction and infrastructure, such as scaffolding, water and gas delivery, fire control system, oil and heat delivery, and other low-pressure liquid delivery. Generally, the length of pipes produced by the erw steel pipes manufacturers is 6m, which can be determined according to the requirements of the buyer.

ERW Steel Pipe's Advantages:
ERW pipe means "high-frequency resistance welded steel pipe", which is different from ordinary welded pipe welding process. The weld is formed by melting the base material of the steel strip body, and its mechanical strength is better than that of general welded pipe.
ERW welded pipe has the characteristics of high production efficiency, low cost, material saving, and easy automation. Therefore, it is widely used in aviation, aerospace, energy, electronics, automobile, light industry and other industrial sectors, and it is one of the important welding processes.
