What is saw pipe?

SAW pipe means Submerged Arc Welded pipe. And from different weld seam, there are two saw pipes, including LSAW and SSAW. As the name suggests, SSAW has a spiral weld seam. And LSAW has a longitudinal weld seam.See all results for this questionWhat is longitudinally welded steel pipe?Longitudinally welded steel pipes are used in onshore and offshore oil and gas pipelines requiring critical service, high performance and tight tolerances. LSAW pipe are also used in conveyance of flammable & nonflammable liquids, and as structural members in construction projects.See all results for this questionWhat is The Differences Between LSAW Pipe and SSAW PipeLSAW Pipe (Longitudinal Submerged Arc-Welding Pipe), also called SAWL pipe. It is taking the steel plate as raw material, mold it by the molding machine, then do double-sided submerged arc welding. Through this process the LSAW steel pipe will get excellent ductility, weld toughness, uniformity, plasticity and great sealing.

What is Spiral welding?
