Difference Between SSAW Steel Pipe And LSAW Steel PipeLongitudinally Submerged Arc Welded Steel pipes, which is abbreviated as LSAW steel pipe. These two types of pipes only have one letters difference, but they are truly different in their manufacturing process.

HSAW pipes, steel pipe, Steel pipe

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 LSAW Pipes Manufacturers in India, CS & MS Longitudinal Longitudinal Welded Steel Pipes or LSAW Steel Pipes:Materials:Carbon Steel, Alloy Steel, Mild Steel.

Types and process of welding pipe-ERW,LW,CW,SAW pipes

Spiral submerged arc welding (SSAW) steel pipe,also called HSAW pipe,welding line shape like a helix.It is using the same welding technology of Submerged Arc-Welding with LSAW pipe.Differently SSAW pipe is spiral welded where the LSAW is longitudinally welded.Manufacturing process is rolling the steel strip,to make the rolling direction have an angle with the direction of the pipe center longitudinal seam steel pipe, longitudinal seam steel pipe < Sponsored Listing Tianjin Xinyue Steel set up several production bases in Tianjin & Hebei Province, manufacturering ERW steel pipe, SSAW steel pipe, LSAW steel pipe, Seamless steel pipe, Scaffolding system and Couplers. , as a subsidiary under the group, is mainly responsible of the exporting business of the group.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.
