The use of seamless stainless steel pipe has expanded into new applications, such as light industry, foodstuff, home electric appliances, kitchen articles, construction and decorations, railroad vehicles; some seamless stainless steel pipe/tube which has excellent corrosion resistant, mechanical properties are suitable to produce general purpose parts, cutting tools, mechanical parts, petroleum refining equipment, bolts and nuts, pump rods, and kitchenware.

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.

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.

Drawing is followed by subsequent annealing and pickling to restore the properties of the entire tube to that of the parent material. The tubes are then posited to impart extra corrosion resistance. Thereafter every tube is electrically marked with material grade, size and manufacturing standard.
