How is Spiral Welded Pipe manufactured?

Jindal spiral welded pipes (SWP) are made from a strip of low carbon structural steel or low alloy structural steel that is rolled into a tube blank at a specific spiral angle and then welded together. It's possible to make it with a thinner strip. Steel is used to manufacture large-diameter steel pipes. Its specifications are specified as outer diameter * wall thickness, and the hydraulic test, weld tensile strength, and cold bending performance of the spiral welded pipes must all meet the criteria. We have developed a comprehensive quality plan, on-site work procedures, and inspection and test programmes to ensure product quality. Quality assurance: The primary inspection/control items for spiral welded pipe adhering to the regulations of production standards are as follows: Dimensions Length and appearance quality Chemical composition Tensile test of welded joint Hydrostatic pressure test Acid etching inspection Non-destructive inspecti...
