What is The Differences Between LSAW Pipe and SSAW Pipe

LSAW 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 A LSAW Steel Pipe? - www.pipelinedubai lasw steel pipeLSAW steel pipe pressure piping should include all straight seam steel pipe pipes that use pressure to deliver gas or liquid. From the point of view of safety production, it is the name of the straight seam steel pipe pressure vessel. Therefore, it is not a pressure pipe in a simple sense.Types of Oil & Gas Pipes: Seamless, ERW, LSAW lasw steel pipeDec 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 option for pipelines above 24 inches (as 24 inches is the maximum size for commercial seamless pipes).

The difference between ERW, SSAW, LSAW(UOE) Steel pipe lasw steel pipe

LSAW (Large-Surface Submerged-Arc Welded Pipe) is produced by using a single medium-thickness plate as a raw material, and pressing (rolling) the steel plate into a tube blank in a mold or a molding machine, adopting a double-sided submerged arc welding method and expanding the diameter. Its product specification range is wide, the toughness, plasticity, uniformity and compactness of the weld lasw steel pipeSEAMLESS STEEL PIPE_ERW STEEL PIPE_LSAW STEEL PIPE lasw steel pipeHunan Shinestar Steel Group(HSSG) was founded in 1978 and our enterprise is the predecessor of branch of China"s oil and gas pipeline science research institute, as the most authoritative pipeline engineering research institute, consists of eight backbone institute and line pipe bureau postdoctoral research stations, oil and gas pipe is "safe" the main body of the national engineering lasw steel pipeLongitudinally Submerged Arc Welded Steel pipes, LSAW lasw steel pipeAfter cold expansion for lsaw steel pipe, steel tube and pipe end diameter will increase by about one percent difference in diameter of the diameter, roundness, and the pipe ends are greatly improved, also have greatly improved the straightness of the steel pipe, steel pipea length of about 0.5% reduction in wall thickness decreases by about 0.8%.

Difference Between LSAW and ERW Steel Pipes

"LSAW steel pipe" is a straight seam submerged arc welded steel pipe. Its main process features are: 1. In the process of steel pipe forming, the steel plate is uniformly deformed, the residual stress is small, and the surface is not scratched.
