SSAW Steel Pipe vs. LSAW Steel Pipe - ESC Group

May 25, 2020 · The difference is SSAW pipes are welded in the helix or spiral position while LSAW pipes are welded in the longitudinal direction. Manufacturing process of SSAW pipe is 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 seam in a spiral line. SSAW Steel Pipe vs. LSAW Steel Pipe - escpilingMay 24, 2020 · May 24, 2020 · There are three (3) manufacturing processes high quality steel pipes are being produced:SSAW (Spiral Submerged Arc Welded), LSAW (longitudi ESC Global:ESC Piling - Fabricator, Supplier & Contractor in the Middle East & Africa SSAW Steel Pipe, SAWL Steel Pipe - Seamless Steel PipeSSAW steel pipe (spiral submerged arc welded steel pipe) is formed by spiral bending of hot-rolled strip steel, and spiral seam steel pipe (also called spiral welded pipe, spiral pipe spiral steel pipe) is formed by automatic welding of submerged arc for inner and outer joints. Material of SSAW Steel Pipe

SSAW Steel Pipe, Spiral Submerged Arc Pipe, SAWL Steel Pipe

Spiral steel pipe (SSAW) is a spiral seam steel pipe made of strip steel coils as raw materials, often extruded and formed by automatic double-wire double-sided submerged arc welding. The spiral steel pipe feeds the strip steel into the welded pipe unit. After rolling by multiple rollers, the strip steel is gradually rolled up to form a round tube blank with an open gap. The reduction of the squeeze roller is adjusted to control the weld gap at 1~ 3mm, and make both ends of the welding Spiral Submerged Arc Welded Steel SSAW Seamless Steel PipeSpiral Submerged Arc Welded Steel SSAW Seamless Steel Pipe.

It is using the same welding technology of Submerged Arc-Welding with LSAW Pipes. Differently SSAW pipe is spiral welded where the LSAW is longitudinally welded.

Types of Oil & Gas Pipes:Seamless, ERW, LSAW

Dec 20, 2018 · An LSAW pipe (submerged arc welding) is manufactured by cutting, bending, and welding steel plates (JCOE process). LSAW pipes compete with seamless and ERW pipes in the size range between 16 and 24 inches but are must-go options for pipelines above 24 inches (as 24 inches is the maximum size for commercial seamless pipes).Low price for Helical Submerged Arc Welding Hsaw Steel Longitudinal Submerged-Arc Welded Steel Pipe Process:LSAW UO(UOE)RB(RBE)JCO(JCOE,COE) DSAW -Double Submerged arc welded Usage:Used for low pressure liquid delivery, such as water, gas, and oil.
