Mother tubes or hollows are procured from reputed manufacturers in India and abroad, and are subjected to a thorough chemical analysis with rigorous physical and mechanical tests.
The best quality mother tubes are then cold-rolled on pilger machines and/or cold-drawn on draw benches with precise pull forces, achieving the desired dimensions and a smooth finish. Tubes are then solution annealed, straightened, pickled, passivated before they are inspected, tested and released for dispatch. Polishing is also done wherever required by a customer.
