LSAW and HSAW 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 HSAW type,steel coils are welded spirally,like a helix,so that High Quality Custom Construction Pipe,Oil Gas Line Pipe LSAW Steel Pipe.Oil Gas Pipeline.Fluid Transportation Pipeline.Structural Steel Pipe.
