Petrosadid Longitudinally Welded and Double SAW

Welded pipe (pipe manufactured with a weld) is a tubular product made out of flat plates, known as skelp, that are formed, bent and prepared for welding. The most popular process for large diameter pipe uses a longitudinal seam weld or Longitudinally Submerged Arc Welded Steel pipes (LSAW). DSAW Pipe is often produced by automatic double-wire double-sided submerged arc welding process.Pipe Manufacturing Process / Methods for Seamless & Welded pipe with filler material can be used in the manufacturing of long radius bends and elbow. Welded pipes are cheaper with compared to the seamless pipe and also Weak due to the weld. There are different welding methods used to weld the pipe. ERW- Electric Resistance Welding. EFW- Production Process of Straight Seam Welded PipeApr 30, 2021Straight seam steel pipe is a steel pipe whose weld seam is parallel to the longitudinal direction of the steel pipe. Straight seam steel pipes can be divided into high-frequency straight seam steel pipes (ERW tube) and submerged arc welded straight seam steel pipes (LSAW tube) according to the production process.
