Welded steel pipes can be roughly divided into three categories according to the forming process 1. Resistance welded steel pipe. Resistance welding steel pipe, English name ERW (Electric resistance welded Pipe), the weld type is straight seam. Resistance welding is a pressure welding method without filler metal.API 5L Welded (ERW, LSAW, SSAW) Steel Line PipeThere are 3 welding types ERW (Electric Resistance Welding), LSAW (Longitudinally Submerged Arc Welding), and SSAW (Spirally Submerged Arc Welding) welding types. ERW pipe is a type of Resistance pipe stands apart from welded pipe and DC welded pipe in
ERW Electric Resistance Welded, OD up to 24 inch. DSAW/SAW Double Sub-merged Arck Welding, substitute welding methods than ERW for larger diameter welded pipes. LSAW Longitudinal Sub-merged Arc Welding, also called JCOE pipe, OD up to 56 inch. SSAW / HSAW Spiral Sub-merged Arc Welding, or Helical SAW, OD up to 100 inch.API Seamless Steel Pipe - Permanent SteelThe welded steel pipe pipes, which was commonly used in oil pipelines in China, are spiral submerged arc welded pipes (SSAW), straight seam submerged arc welded pipes (LSAW) and electric resistance welded pipes (ERW). Steel pipes are generally used when the pipe diameter is less than 152 mm.Brief Description and Comparisons of LSAW, SSAW, and High quality steel pipes are produced from three (3) manufacturing processes Seamless, LSAW (longitudinal-seam submerged arc welding), and ERW (electric resistance welding).
