Product Advantages of LSAW Steel Pipe (1) Without the unwind process, the base material indentation, scratch less. (2) The wrong side, slotted, and other easy-to-diameter perimeter control, excellent welding
Longitudinally Submerged Arc Welded Steel pipes, LSAW Mainly as a field gathering pipe and internal high-pressure natural gas pipeline of small-caliber, long-distance pipelines for oil and gas a small number, the vast majority of long-distance pipeline is the use of high-frequency straight seam welded pipe (ERW), spiral submerged arc welded pipe (SSAW), LSAW steel pipe (LSAW) three.
Process Difference between Spiral Steel Pipe and Straight Nov 10, 2020 · Welded steel pipes refer to steel pipes with seams on the surface that are welded by steel strips or steel plates that are bent into round or square shapes. The blanks used for welded steel pipes are steel plates or strip steels. It can be divided into straight seam welded pipe (ERW, LSAW) and spiral welded pipe (SSAW).
Straight seam submerged arc (LSAW steel pipe) is produced by using a single medium-thick plate as the raw material, pressing (rolling) the steel plate in a mold or forming machine, using double-sided submerged arc welding and expanding the diameter. The finished product has a wide range of specifications, good toughness, plasticity, uniformity
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).
