ERW pipe(electric welded pipe) means electric resistance welded pipe, and it is a resistance welding by 10-500 kHz of high-frequency current. The raw material of electric resistance welded steel pipe is hot rolled steel coil which is made of steel billet, and the usual erw pipe grade is Q195, Q215, Q235, Q355 in China steel grade, which are same material with S195, S235, S355 in Europe, and SS400 in Japan. Steel coil firstly will be cut into strip, the strip width is according to the perimeter of pipe, 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 speaking, the length of pipes produced by the erw steel pipe suppliers are 6m, which can be determined according to the requirements of the buyer.
