Usually divided into metric welded steel pipe, welded thin ERW carbon steel pipe vs spiral pipe1. The geometric accuracy of ERW steel pipe is high, while the geometric accuracy of spiral welded pipe is low, which makes it difficult to butt the weld to the spot. 2. The welding coefficient of ERW pipe is 100% and that of spiral welded pipe is 130% - 200%.
Fourth, the steel pipe geometric size 1, ERW carbon steel pipe geometric size of the higher accuracy; and spiral welded pipe geometry accuracy is low, resulting in on-site construction of the weld weld docking difficulties. 2, ERW carbon steel pipe weld coefficient is 100%; spiral welded pipe weld coefficient of 130% -200%. Electric Resistance Welded Pipe, ERW Steel Pipes, Electric Steel pipe for pipe technology, can be divided into (SML), mainly as the Oilfield internal transportation pipeline and small-diameter high-pressure natural gas pipeline, used for a small number of long-distance gas pipeline, the vast majority of long-distance pipeline with Direct seam high frequency (ERW), spiral submerged arc (SSAW), LSAW three (LSAW).
