The two main types of ERW are 1.See more on theprocesspipingLongitudinally Submerged Arc Welded Steel pipes,LSAW Mainly as a field gathering pipe and internal high-pressure natural gas pipeline of small-caliber,long-distance pipelines for oil and gas a small number,the vast majority of long-distance pipeline is the use of high-frequency straight seam welded pipe (ERW),spiral submerged arc welded pipe (SSAW),LSAW steel pipe (LSAW) three.

May 25,2020·There are three (3) manufacturing processes high quality steel pipes are being produced SSAW (Spiral Submerged Arc Welded),LSAW (longitudinal submerged arc welding),and ERW (electric resistance welding).Let us take further on LSAW and ERW pipes.The two main types of LSAW pipes are Longitudinal (single or double straight seam weld,DSAW) and Spiral (SSAW,HSAW,or SAWL pipe).Steel Pipe,OCTG,Casing and Tubing Supplier - OctalOctal offers welded (ERW,LSAW,SSAW) and seamless steel pipe for sale,available in Black Carbon Steel Pipe for sale.ASTM A53 B,A106 B,A179,A192,A333 Gr 1 to Gr 6Straight seam weldedsteelpipesare divided into highfrequency resistance weldingand submerged arc weldingaccording to the weldingprocess.Straight seam submerged arc weldingis referred to as LSAW,and longitudinal highfrequency resistance weldingis referred to as ERW.Differences Between ERW and LSAW Steel PipeWas this helpful?People also askWhat does ERW stand for in steel pipe?What does ERW stand for in steel pipe? ERW steel pipe is a high-frequency straight seam resistance welded pipe.The English abbreviation for Electric Resistance Welding is abbreviated as ERW.It is used to transport vapor and liquid objects such as oil and natural gas,which can meet various requirements of high and low pressure.Difference Between LSAW and ERW Steel Pipes
