Longitudinal Submerged Arc Welding (LSAW) Processes

Longitudinal submerged arc welded (LSAW) pipes manufacture process is bending and welding wide steel plates to pipes from leveled hot rolled coils by both the JCOE and UOE (the forming process in which the plate like the letter "J", "C", "O" or "U" shape, then expansion) forming processes. Longitudinal Submerged Arc Welding LSAW Steel Pipes LSAW Steel Pipe s (longitudinal submerged arc welding) are usually the most economical solution when high wall thickness is required due to high internal or external pressure. LSAW Steel Pipe s are larger in diameter than ERW (resistance welding), typically from 16 inches (406 mm) to 60 inches (1500 mm). Longitudinal Submerged Arc Welding LSAW Steel Pipes Longitudinal submerged arc welding is a special welding technology used in pipe production. Because of high internal or external pressure, the final product needs high wall thickness.
