Manufacturing of Stainless Steel Welded Pipes

Stainless Steel Welded Tubes Manufacturing Process - Scoda Tubes Ltd

The mother hollow is then drawn with the help of Tungsten Carbide Die and Plug to get the desired diameter and thickness. It is then annealed, straightened, cut, deburred, pickled and passivated. The tubes then undergo a 100% hydro-testing, visual and dimensional examination, 100% PMI testing They are then marked and suitably packed before dispatch.
