LSAW welded Pipe (Longitudinal Submerged Arc-Welding 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. The process method: UO(UOE)、RB(RBE)、JCO(JCOE).
Usage: Used for low pressure liquid delivery, such as water, gas, and oil.
