Shape & Use: A hollow cylinder with a longitudinal seam. Used for low to medium-pressure transmission of water, oil, and gas, as well as structural scaffolding.
Manufacturing Process: Electric Resistance Welding. Flat steel coils are unrolled, bent into a cylindrical tube shape by a series of rollers, and the edges are fused together using a high-frequency electrical current without the addition of filler metal.
Welded steel pipe includes ERW pipe, LSAW pipe and SSAW pipe. These pipes are made with steel strip or steel plate. The manufacturing processes first bend the steel sheet/plate, then weld into circular, square or other shapes. Welded pipe has the characteristics of high production efficiency, low cost and saving material.
