Differences Between SAW and ERW Pipe Winsteel GroupDec 19, 2018 · SAW 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.
Dec 27, 2006 · We are using ERW pipes (below 12") in treated cooling water service the most the failures occured in the weld seam.Whereas no failure was reported in the DSAW/EFSW pipes.

LSAW (Longitudinally Submerged Arc Welded Steel pipes) in leaflets plate as raw material, the steel plate in the mold or molding machine pressure (volume) into using double-sided submerged arc welding and flaring from production.
Nov 20, 2020 · Longitudinal Submerged Arc Welding (LSAW) Longitudinal Submerged Arc Welding is the type of welding basically used for pipe which manufactured with weld. This is a specific welding technique used in pipe production. Production from longitudinal submerged arc welding is required high high wall thickness due to high internal and external pressure. PRODUCTS MKS PIPE & STEELWe supply ERW/HFW pipe in a variety of grades meeting ASTM/ASME and API5L standards including A/SA53, A500, API5LB, X42, X46, X52, X56, X60, X65, X70, X80 in both PSL 1 and PSL 2. DSAW / LSAW PIPE Double Submerged Arc Welded/Longitudinal Submerged Arc Welded steel pipe is available in different formats and ranges from 16 to 120 in diameter.
DSAW Pipe is distinguishable by the spiral DSAW seam that runs the length of the pipe up to 155 feet. Advantages:The submerged welding process protects the steel from the contamination of air impurities. The welds also penetrate 100% of the pipe wall, producing a very strong bond. SMLS Pipe.

May 25, 2020 · The two main types of LSAW pipes are:Longitudinal (single or double straight seam weld, DSAW) and Spiral (SSAW, HSAW, or SAWL pipe). The difference between DSAW and LSAW is that DSAW pipes have a seam weld in the inside and outside of the pipe, while LSAW pipes have a single seam weld on the outer surface, longitudinal or cross sectional. The difference between ERW, SSAW, LSAW(UOE) Steel pipe Apr 22, 2018 · LSAW (Large-Surface Submerged-Arc Welded Pipe) is produced by using a single medium-thickness plate as a raw material, and pressing (rolling) the steel plate into a tube blank in a mold or a molding machine, adopting a double-sided submerged arc welding method and expanding the diameter.
