Longitudinal submerged arc welded pipe, a type of longitudinally welded steel pipe produced by using the double-sided submerged arc welding method. LSAW pipes are welded tubular products made out of flat plates that are formed, bent and prepared for welding. LSAW pipes are welded with a straight seam that runs length wise across the pipe. LSAW pipes are commonly used in high pressure oil and gas pipelines because of their shorter welded seams and easier serviceability. These pipes are commonly required for sections of a pipeline that extend across areas with high population or building sensity or involve subsea applications. Due to their high raw material costs and the substantial investment required for LSAW pipe prodcution lines, LSAW pipes are generally more costly to produce than SSAW pipes.
