Difference between ERW and DSAW pipes - Sunny Steel

Difference between ERW and DSAW pipes. Difference between ERW and DSAW pipes is generated in the carbon steel smelting defect smelting and casting process, such as segregation, non-metallic inclusions, porosity, shrinkage and cracks. Double Submerged Arc Welded (DSAW) steel pipe is available in straight and spiral welded formats and used in a variety of applications. Differences Between SAW and ERW Pipe Winsteel GroupDec 19, 2018 · 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, Different Weld Seam Between SAW and ERW Pipe . The surface quality is very important for pipes. Though both SAW and ERW pipes all have a weld seam. But for weld seam of ERW pipe is flat.

Differences between ERW Steel Pipe and HFW Steel Pipe

The high frequency welding (HFW) is mainly used in ordinary or thin wall steel pipe. It includes contact welding and induction welding. Direct current welding is generally used for small caliber steel tubes. In general, HFW is one of ERW production methods, it adopts the high frequency welding process. So, ERW steel pipe includes HFW steel pipe. HFW welded Steel Pipe API SPEC 5L - LIDA (China HFW welded Steel Pipe API SPEC 5L - LIDA Products Made In China, China Manufacturer.

Casing Pipe 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.
