API 5L LSAW MILD STEEL PIPE Basic infor mation:Longitudinally Submerged Arc Welding (LSAW / SAWL) Pipe:the pipe is produced by double-side submerged arc welding and expanded diameter. During the production used pre-welding and then precision welding process, it is stable welding process and high quality weld. Comparison Between LSAW Pipe And SSAW PipeLSAW Pipe (Longitudinal Submerged Arc-Welding Pipe), takes the steel plate as raw material. Then mold it by the molding machine, Finally, do double-sided submerged arc welding. Through this process, the LSAW steel pipe will get excellent ductility, weld toughness, uniformity, plasticity, and great sealing.

Forming Process of LSAW Steel Pipe (UOE vs JCOE)

Dec 04, 2020 · Longitudinal submerged arc welded pipe (LSAW) is generally made of steel plate as raw material. After different forming processes, double-sided submerged arc welding and post-weld diameter expansion are adopted to form welded pipe. High Quality LSAW Steel Pipes Suppliers, Factory in IndiaAbout LSAW Pipes. 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).

LSAW Steel Pipe - Gnee steel

LSAW Pipe 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. LSAW Steel Pipe - Hunan Great Steel Pipe Co., Ltd.This is large diameter longitudinal submerged arc welded (LSAW) pipe production line in China. The mill adopts progressive bending process, featuring evenly distributed forming stress, high uniformity of dimension, infinite sizes variation&wide prouct range, and high flexibility, etc.

LSAW Steel Pipe - for Construction, Oil and Gas Pipeline

LSAW (Longitudinal Submerged Arc Welding) pipes are straightly welded; it is widely used in heavy industry to convey oil, coal slurry, etc. Under strictly operation according to ISO9001:2008 International Quality System, SMC has always held the management concept of quality first, credit first, customer first to develop constantly, we have always persisted in scientific innovation.
