We are Manufacturer, Supplier & Exporter of Duplex S31083 / S32205 Flanges through the web of our in-house production centre fabricating flanges in rare metal types. We have a long procedure of quality control, under which we carefully assess all our products on the basis of various parameters. We test and verify the accuracy and precision of our Duplex Steel UNS S31803 Blind Flanges, qualifying fit enough to work as water-proof seals to pipe ends. The2205 (UNS-S32205/S31803) Duplex Steel Flangessupplied by us are accepted by clients in various spheres of the industries ranging from basic industries such as Sugar, Paper, Textile, Engineering to more complex such as Oil & Gas, Petrochemical, Chemical & Fertilizers, Power Generation and Nuclear Industries.

The presence of corrosive water and high temperatures means that Stainless Steel UNS S32205 Pipe Flanges is the ideal material for desalination plants, making them easier and cheaper to build to the scale required. The starting force needed for bending in Stainless Steel UNS S31803 Pipe Flanges is slightly higher than for standard austenitic stainless steels (SS 304L and SS 316L). The addition of molybdenum and slightly higher nickel content make Duplex Steel S31803 Blind Flanges suitable for architectural applications in severe settings, from polluted marine environments to areas with sub-zero temperatures.
