Difference between ERW, SSAW, LSAW - Sunny Steel

Difference between ERW, SSAW, LSAW. 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).Difference between saw and erw pipe2, ERW pipe weld coefficient is 100%; spiral welded pipe weld coefficient of 130% -200%. The weld length of spiral pipe is much longer than that of erw pipe, and the incidence of defects also increases synchronously. 3, ERW pipe weld height remaining close to zero, the naked eye is not visible; spiral steel pipe on the outside surface must erw welding spiral welded saw q235bDifference between ERW, SSAW, LSAW - Sunny SteelDifference between ERW, SSAW, LSAW.
