LSAW and SSAW are variants of SAW (submerged arc welded) pipes. The difference between them is the way they are welded. In LSAW pipes, the welding is longitudinal, which means that steel (hot rolled coil plate) is rolled into a pipe and the seam is welded longitudinally. In the SSAW type, steel coils are welded spirally, like a helix, so …
LSAW pipe has higher costs than SSAW pipe. LSAW Pipe. LSAW pipes are produced by moulding hot-rolled coil plate steel into a cylinder and joining the ends together by welding in a straight line.
