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 lsaw steel pipelineLSAW 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 pipein a simple sense.Types of Oil & Gas Pipes: Seamless, ERW, LSAW lsaw steel pipelineDec 20, 2018 · Learn about the 3 types of steel pipes used in the petrochemical industry: seamless, ERW (electric resistance welding), and LSAW (longitudinal submerged arc welding). A seamless pipe is manufactured by drawing a solid steel billet through a piercing rod. Welded pipes are produced by cutting, bending, welding coils (ERW), or steel plates (LSAW).

Types of Oil & Gas Pipes: Seamless, ERW, LSAW lsaw steel pipeline

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).SSAW Steel Pipe vs. LSAW Steel Pipe - ESC GroupThe welding line of LSAW pipe is around 60% lesser than of SSAW pipes. Using steel plates, quality of LSAW pipe can be tested by non-destructive procedures. While SSAW pipes using hot-rolled coils should be tested with destructive methods such as x-ray. LSAW pipes adopt welding after molding process where various checks can take place.SAWL Line Pipe - LSAW Steel Pipe,SAWL Steel Pipe lsaw steel pipelineLSAW Steel Pipe. Short for submerged arc welding longitudinal,SAWL steel pipe is made of hot rolled steel plate by JCOE and UOE. JCOE means the forming process, that is, J shape, C shape, O forming, insider&outside welding and cold expansion after welding.
