Difference between ERW, SSAW, LSAW - Sunny Steel

Difference between ERW, SSAW, LSAW. Steel pipe for pipe technology, can be divided into (SML), mainly as the Oilfield internal transportation pipeline and small-diameter high-pressure natural gas pipeline, used for a small number of long-distance gas pipeline, the vast majority of long-distance pipeline with Direct seam high frequency (ERW), spiral submerged arc (SSAW), LSAW three (LSAW).Helical Welded Pipes and Longitudinal Welded PipesHelical Welded Pipes and Longitudinal Welded Pipes. Welded line pipes enjoy a wide acceptance in oil and gas transporting market for its selection variety and relatively low cost. According to the different welding seams, welded line pipes can be further categorized into two types, the helical welded pipes and longitudinal welded pipes.Helical Welded Pipes and Longitudinal Welded PipesHelical Welded Pipes and Longitudinal Welded Pipes.

Introduction to Welded Pipe Manufacturing - The Process

The SSAW pipe diameter range is from 20 inch (406 mm) to 100 inch (2540 mm).The advantage part is we can get the different diameter of SSAW pipes with the same size of the steel strip, there is a wide application for the raw material steel strip, and welding seam should avoid the primary stress, good performances to bear the stress.LSAW PIPE - Piping System SolutionsJan 27, 2020 · Straight seam welded steel pipe , Longitudinal Submerged-Arc Welded Steel Pipe The advantages of LSAW (Longitudinal Submerged Arc Welding) pipes are straight welding. They are widely used in heavy industry to convey oil, coal slurry, etc.LSAW Pipe Manufacturing Process - Seamless Steel PipeThe two main types of LSAW pipes are the longitudinal (with a single or double straight seam weld, DSAW) and the spiral type (called, HSAW, SSAW or SAWL pipe). Therefore, the difference between DSAW vs. LSAW is that DSAW pipes have a seam weld in the inside and outside of the pipe, whereas LSAW pipes have a single seam weld on the outer surface.

Types of Oil & Gas Pipes: Seamless, ERW, LSAW longitudinal seam welded steel pipe lsaw

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 longitudinal seam welded steel pipe lsawThe two main types of LSAW pipes are the longitudinal (with a single or double straight seam weld, DSAW) and the spiral type (called, HSAW, SSAW or SAWL pipe). Therefore, the difference between DSAW vs. LSAW is that DSAW pipes have a seam weld in the inside and outside of the pipe, whereas LSAW pipes have a single seam weld on the outer surface.What is The Differences Between LSAW Pipe and SSAW PipeLSAW 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.
