LSAW Pipe：
LSAW Pipe (Longitudinal Submerged Arc-Welding Pipe)/DSAW (Double Submerged arc welded), is taking the steel plate as raw material, mold it by the molding machine, then do double-sided submerged arc welding. Through this process the LSAW steel pipe will get excellent ductility, weld toughness, uniformity, plasticity and great sealing.
