Manufacturing of welded pipes & tubes is carried out on sophisticated tube mills, where the raw material, i.e. SS Strips, sourced from only the world-renowned sources is fed. The strips are welded into tubes/ pipes using TIG/ Plasma/ Laser welding. Under this process, the edges of the strip are heated and fused together in a protective atmosphere of Argon gas using a non-consumable electrode without the addition of any filler material.
After cutting to size, and depending on the customer requirements, the tubes are then solution-annealed, straightened, cut to final size, pickled, passivized and polished before it is subjected to various tests for dispatch.
When tubes are made on fully automatic tube mills, the product is bright annealed, subjected to NDT, size checked, polished if required and stencil marked on line itself.
Tube straightening Machine (TSM) plays a vital role in improving the quality of ERW, SS Tubes beign produce on Tube Mills & Draw Benches respectively. There are certain application of Tubes in Engineering & Automobile industry where straightening of the Tube is of prime importance.
Solution Annealing Solution annealing is the heat treatment most frequently specified for stainless steels The main objective is to dissolve the phases that have precipitated during the thermo mechanical processing of the material, especially the chromium-rich carbides. Quenching is the cooling of the material from the higher temperature of the room temperature.
Stainless steel tubing and piping are found in a wide variety of applications, ranging from the equipment and systems used by the processing industries to structural and ornamental end-uses, as well as in consumer-oriented products, e.g., the exhaust systems for automobiles and motorcycles. Both the interior and exterior surfaces of stainless steel tubing can be polished mechanically, typically using 120, 150 or 180/220 grit. As the grit number is increased, a smoother surface is obtained
A hydrostatic test is a way in which our pipes are quality tested and can be tested for strength and leaks. The test involves filling the vessel or pipe system with a liquid, usually water, which may be dyed to aid in visual leak detection, and pressurization of the vessel to the specified test pressure.
