Manufacturing Process of Stainless Steel Pipe:

The process commences with the formation of welded mother tube on the tube mill from imported and tested prime quality stainless steel strips. The latest TIG multi electrode welding technique is employed for superior weld quality and 100% Fusion, with argon purging, No filler metal added.

These mother tubes are solution annealed at 1060 D. 1100 D. C in continuous annealing furnace followed by immediate quenching to prevent chromium carbide precipitation.

Annealing of mother tuber ensures:

A) Removal of stress induced during tube forming and cold drawing:

B) Sufficient ductility and softness for cold drawing:

C) Transformation of the weld zone to austenitic nature,

D) Re crystallization of metallic grains to original form and thereby improving corrosion resistance.

During annealing, scales are formed on the surface of the tubes. In order to remove these, the tubes are pickled by immersing into hot pickling solution made of nitric acid, sulphuric acid and hydrofluoric acid.
