LSAW, SSAW, and ERW Pipes Description and Comparison

May 06, 2020 · The difference is SSAW pipes are welded in the helix or spiral position while LSAW pipes are welded in the longitudinal direction. SSAW pipe takes form by rolling and welding a steel strip in a way that the pivotal direction is oblique to the axis or pipe center, making the weld Longitudinal Submerged Arc Welding (LSAW) Processes The material of LSAW steel pipe is unit middle or heavy thickness sheet, coiled in the molding or forming machine, welded by double submerged arc welding and expand the diameter. The specification scope is wide, and have good toughness, ductility, uniformity, compactness, etc. Lsaw pipe ZS Steel Pipe8inch straight seam welded fluid pipe with ASTM A53 GR.B; LSAW welded black steel pipe for gas water oil pipeline API standard; Lsaw pipe; Product by categories.

Welded Steel Pipe

Longitudinal high-frequency welded steel pipe has the characteristics of relatively simple process and fast continuous production, and has wide use in civil construction, petrochemical, light industry and other sectors. Mostly used to transport low pressure fluids or made into various engineering components and light industrial products. What Is A LSAW Steel Pipe? - pipelinedubaiJul 21, 2018 · LSAW pipes are also used in conveyance of flammable & nonflammable liquids, and as structural members in construction projects. LSAW pipe (longitudinal Submerged Arc Welding Pipe) is fromed by JCOE with one straight welded seam, the outer diameters usually from 323mm to 1420mm.LSAW Welded Steel Pipe Features and Manufacturing ProcessLSAW (Longitudinal double submerge arc welding) carbon steel pipe is a type of SAW pipe made of steel plates that were hot rolled by JCOE or UOE forming technology. JCOE technology represents the shaping and forming processes involved during manufacturing as well as the inner and outer welding and cold expansion carried out after welding.
