Contact SupplierWe are a specialist in manufacturing ERW Pipes. We are praised for our enviable manufacturing infrastructure, vast experience and depth in understanding of the subject. Our capabilities match with the best in business, globally.
Equipments like fully integrated and automatic tube mills (with online annealing, eddy current testing, marking etc.), semi automatic tube mills, solution annealing furnaces, cold-drawing facilities, multiple support machines like straightening, cutting, ends facing, polishing, high capacity pickling & passivation setup, U-bending facility etc., give a consummate versatility that is unparalleled.
The manufacturing of ERW Pipes 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, passivated and polished before it is subjected to various tests, marked and released for dispatch.
When pipes 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.
