      • Ability to supply tubes with stringent NDT Testing, Special Chemistry, Lower Residual Stress values, higher Corrosion Resistance etc.
      • Hot Extruded Mother Hollows are used to manufacture tubes for producing finished tubes
      • Controlled dimensional tolerance as per customer requirement.
      • Solution Annealed & Passivated
      • Stabilization Heat Treatment
Stainless Steel Seamless Pipe Manufacturing Process - Scoda tubes

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.
