The main difference between them is the method they are being welded. In API 5L LSAW pipes, the welding is longitudinal, which signifies that steel is rolled into a pipe and the seam is welded longitudinally. However, in API 5L HSAW Pipes, steel coils are welded spirally, like a helix, so that the coil (strip) presumes the form of a pipe.ASTM A252 Pipe Pile Specifications (In seamless & welded lsaw steel pipe rolled and welded pipeASTM A252 is the standard specification for welded and seamless steel pipe piles.
