Stainless Steel Welded Pipe Manufacturing Process
The Stainless Steel Welded Pipe Manufacturing Process commences with the formation of welded mother tube on the tube mill from imported and tested prime quality stainless steel strips.
Latest, 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℃ and 1100℃ 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.
