What is The Differences Between LSAW Pipe and SSAW Pipe

LSAW Pipe (Longitudinal Submerged Arc-Welding Pipe), also called SAWL pipe. It 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.Submerged arc welding pipe, SAW pipes, SAW pipe sawl submerged arc welded pipesSubmerged arc welding pipe, SAW pipes.
