Procured mother tubes or hollows from leading suppliers from India & Abroad are directed to a through chemical analysis and strict physical / mechanical tests. The mother tube are subsequently cold-drawn on the benches with determined precise and force. The OD of the tube is there by reduced by tension through a die and a fixed or floating plug, to get a precise mechanical dimensions and a uniform surface finish. These tubes are then subjected to various process like pickling, Passivation, Hydro testing, Polishing, Inspection, Marking before Packing & Despatch.
Annealin, or heat treatment, of the tube is carried out in fully automated conveyor. It consists of heating the tubes to a specified temperature and immediate quenching in circulating water thereafter.
After the anealing operation, the tubes are straightened with a straightening machine. In addition to giving a high degree of straightness, the tubes are also rounded up during the operation.
The excellent properties of Stainless Steel Tubes & Pipes, including their high aesthetic & hygienic value, low maintenance and high durability, has led to an increased demand for polished tubes & pipes in architecture, general engineering, dairy & food-processing sectors, among others. To meet such demands for high-quality externally polished tubes and pipes, Scorodite is equipped with a state-of-the-art polishing machine. A range of finishes, from 120 grit up to mirror finish, is made available as per customer's requirement.
Cold rolled Stainless Steel strips are welded into tubes in the state of the art tube mills under fully automated precision process.
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 metals. 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 & Despatch.
