LSAW Pipe 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.

structural pipe is welded pipe sized tubing made from flat-rolled steel, formed through a roller system and welded using electric-resistance welding.
