FeedbackPetrosadid Longitudinally Welded and Double SAW

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). What happens during the ERW pipe welding process?What happens during the ERW pipe welding process?During the ERW pipe welding processes, the electric current will make the heat when flow through the contact surface of the welding area. It will heat the 2 edges of the steel to a point that the edges can form a bond.Differences between ERW Steel Pipe and HFW Steel Pipe What is the difference between dsaw and ERW pipe?What is the difference between dsaw and ERW pipe?Difference between ERW and DSAW pipes is generated in the carbon steel smelting defect smelting and casting process, such as segregation, non-metallic inclusions, porosity, shrinkage and cracks.
