We distribute & export a range of high quality stainless steel welded /ERW PIPE & TUBE that are used in various industrial applications. These cold rolled stainless steel strips are welded into tubes in the state of the art tube mills under fully automated precision process. Complying with the international standards, these can be availed in various sizes and specifications to suit the diverse requirements of the clients.
The manufacturing of pipes begins with slitting of strips of required width based on the diameter of the tubes to be formed. Stainless steel slitted strips are passed through a series of rollers and tubes are formed automatically on different stands with rolls and welded on fully automated process of TIG welding without the addition of filler metal.
The welding head line is polished continuously with the help of automatic bead polishing machine to produce a perfect bore. The tubes are then passed through a series of sizing rolls to ensure ovality and tolerances. Tubes are then cut to length, cold-drawn, solution annealed, straightened, pickled, passivated and polished before other destructive and non-destructive testing & dispatch.
