Welded Steel Pipe ERW SSAW LSAW DSAW
Welded steel pipe is a type of steel pipes,the other type is seamless steel pipe (SMLS).Welded steel pipes also can divided into ERW,SSAW,LASW,DSAW.
Welded pipes are manufactured by flat steel plate,the pipe’s body has a weld seam.Welded pipes has different types:ERW, SSAW, LSAW, DSAW.The material of welded pipe can be carbon steel,alloy steel and stainless steel pipe.
Carbon steel is an iron carbon alloy with carbon content of 0.0218% ~ 2.11%. Also called carbon steel.
In addition to iron and carbon, other alloy elements are added to steel, which is called alloy steel.
Stainless steel is the abbreviation of stainless and acid resistant steel. Steel resistant to weak corrosive media such as air, steam and water or stainless steel is called stainless steel.
