STAINLESS STEEL TUBES

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 passed to impart extra corrosion resistance. Thereafter every tube is electrically marked with material grade, size and manufacturing standard.

The tubes are then coated with proper lubricant and then cold drawn over a drew bench:

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 hydrofluoric acid.

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

The Process commences with the formation of welded mother tube on the tube mill from 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
