Stainless Steel Seamless Tubes & Welded Tubes

Seamless Pipes The seamless pipes and tubes offered by us are widely appreciated, owing to their dimensional accuracy, high strength, corrosion resistance and durability. For manufacturing these pipes and tubes, we procure mother tubes or hollows from leading suppliers from China and  abroad that are directed to a thorough 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 thereby 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 annealing, pickling, passivisation, hydro testing, polishing, inspection, marking before packing and dispatching to the clients. Sizes Products Size / Range Heat Exchanger Tubes 10.00 mm to 50.80 mm OD Instrumentation Tubes 6.00 mm to 25.40 mm OD Pipes 1/8" to 6" NB Grades 300 series : 304,304L,316,316L,317L,321,347H,310 400 series : 409, 409L, 410,430 Standards Conforming to international specifications of ASTM A-213, A-249, A-269, A-312, A-358, A- 688 and its equivalents in ASME, DIN, NFA, JIS etc. Specification Products Specification Heat Exchanger Tubes ASTM A-213, A-268, A-269, A-270, A-789 DIN -17456 & 17458 ( Class -1) U tubes as per customer's drawing. Instrumentation Tubes ASTM A-213, A-269, DIN -17456 & 17458 ( Class -1) Pipes ASTM- 312, A-790 Annealing Annealing, 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. Straightening After the annealing 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. Polishing The excellent properties of Stainless Steel Tubes and Pipes, including their high aesthetic & hygienic value, low maintenance and high durability, has led to an increased demand for polished tubes and 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.
