Carbon steel welded pipes can be divided into three types: Longitudinal submerged arc welded steel pipes (LSAW), Spiral welded steel pipes (SSAW), and Electric resistance welded Steel Pipe (ERW, also called high-frequency straight seam welded steel pipes ) according to the forming method of the weld seam.
Stainless Steel Pipe OD and Wall Thickness Explained
Sep .22.2026
The national standard thickness of stainless steel pipes should first be determined by the nominal diameter or outer diameter of the pipe. The national standard for thin-walled stainless steel pipes is divided into the series and the l series. For pipes with the same nominal diameter, the outer diameter of the pipe will vary slightly.
