ERW vs LSAW pipe - Knowledge - Cangzhou Steel Pipe erw vs lsaw pipe. ERW is - high frequency resistance attachment - straight seam welded pipe;LSAV is - submerged arc welding - straight seam welded pipe;Both belong to the straight seam welded pipe, however the 2 attachment method is totally different, the utilization is totally different, thus it can't represent the straight seam welded pipe alone.SSAW- spiral attachment - pipe is a lot of common.
