ERW steel pipe is Electric Resistance Welding, which is different from the welding process of ordinary welded pipe. The weld is formed by melting the base material of the steel strip body, and its mechanical strength is better than that of ordinary welded pipe.

ERW steel pipe has the advantages of using hot-rolled coil as raw material, the uniform wall thickness can be controlled at about ±0.2mm, the two ends of the steel pipe are in accordance with the American APL 5L standard or GB/T9711.1 standard, the pipe end is beveled, and the length is delivered. Etc. In recent years, various natural gas pipeline network projects and gas companies have widely adopted ERW steel pipes as the main steel pipes in urban pipeline networks.
