The Difference and Use of ERW, LSAW and SSAW Steel Pipe

ERW is high frequency resistance welding straight seam welded pipe; LSAW is submerged arc welding straight seam welded pipe; both belong to straight seam welded pipe, but the two have different welding processes and different uses, so they cannot represent straight seam welded pipe alone. SSAW spiral welding spiral welded pipe is more common.Difference between ERW, SSAW, LSAW Alloy Pipe, Tubes 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).Differences Between SAW and ERW Pipe Winsteel GroupSAW pipe means Submerged Arc Welded pipe. And from different weld seam, there are two saw pipes, including LSAW and SSAW. As the name suggests, SSAW has a spiral weld seam. And LSAW has a longitudinal weld seam. ERW pipe means Electric Resistance Welded pipe. Second Differences Between SAW and ERW Pipe We Will See It From The Weld Seam.

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.Products, ERW DSAW SMLS pipe Weiler Pipe llc.ERW PIPEElectric Resistance Welded (ERW) is cold formed from a ribbon of steel that is pulled through a series of rollers to produce tubes. The tubes are then fused with an electric charge without the use of welder filler material. Available finishesBare; Coated; Available in lengths up to and over 100 feet and a variety of diameters.Difference between ERW Pipes, SSAW Pipes and LSAW Pipes Spiral Submerged Arc Welding Pipes Spiral submerged arc welded (SSAW) pipes has spiral welding joints and the pipes are welded and formed at the same time. The strip steel with the same specification can produce SSAW pipes with various diameters. The welding joints can avoid major stress and have better force resistance.

Generally, welded steel pipes can be divided into ERW pipes, SSAW pipes and LSAW pipes according to the welding technologies involved to manufacture the product. Submerged arc welded pipes are manufactured by bending and welding ordinary steel plates. The SAW type is commonly used for oil and gas transmission lines (API 5L).LSAW Steel PipePipe TypeLongitudinal Welded Pipe, Longitudinal Submerged Arc Welded Pipe ApplicationUsed for Fluids Transmission, Structural Support in Industrial Construction SpecificationOD406mm ~ 1422 mm WT6.4mm ~ 44.5mm LENGTH5mtr ~ 12mtrLSAW Steel Pipe, DSAW Steel Pipe, Welded Steel PipeTypes Standard SY/T5040 2000 SY/T5037 2000 SY/T9711.1 1977 ASTM A252 AWWA C200 97 API 5L PSL1 Tube end OD deviation

Comparison Of ERW Steel Pipe And LSAW Steel Pipe

Aug 22, 2018· The welded steel pipes are mainly divided into three processesstraight seam electric resistance welding (ERW), spiral submerged arc welding (SSAW) and straight seam submerged arc welding (LSAW). .

Difference between ERW and EFW Welded Steel Pipe

ERW is the first letter abbreviation for electric resistance welding. ERW tube and submerged arc welding pipe significantly different, using a pressure free filler metal welding, the weld is not filled with other ingredients, relying on high frequency current skin effect and proximity effect, instantly heating the plate edge to welding temperature by squeezing rollers squeeze formed weld Welded Pipe Manufacturing Methods SAW, ERW, EFW & Oct 14, 2016· In this video, you will learn about Welded Pipe Manufacturing Process such as SAW, ERW, EFW & HFW.. Welded Pipes are manufactured from Plate or from continues Coil or strips. To manufactured welded pipe, first, Plate or coil is rolled in the circular section with the help of plate bending machine or by a roller in the case of continues process.Introduction to Welded Pipe Manufacturing The Process The LSAW pipe diameter range is larger than ERW, normally from 16 inch (406mm) to 60 inch (1500mm). Good performances on high pressure resistance, and low temperature corrosion resistance. Spiral Submerged Arc Welding (SSAW) Process. In Spiral Submerged Arc Welding (SSAW) Process, also known as HSAW pipe, welding line shape like a helix.
