ANSI B16.5 SMO 254 Orifice Flanges, SMO 254 Flanges Suppliers, SMO 254/6Mo Pipe Flanges, Global Supplier of SMO 254 Weld Neck Flange, Werkstoff No 1.4547 SMO Socket Weld Flanges Manufacturing, SMO 254 ASTM A403 Threaded Flanges Suppliers, ANSI B16.5, ANSI B16.47, B16.48, SMO 254 Forged Flanges Leading Manufacturer & Stockist in Mumbai, India.

The addition of copper in our Weld Neck Flanges improves the resistance in certain acids. The SMO 254 Orifice Flanges have an excellent impact strength because of its austenitic microstructure, both at room and cryogenic temperatures. Our SS SMO 254 Ring Joint Flanges must have a filler material for best strength properties. These specific levels of Ni, Mo, Cr, and N in this “super austenitic” chemical composition allow SMO 254 Tube Fittings to resistance to corrosion cracking, combine impact toughness, with pitting and crevice corrosion.

Our pipe fittings are available in different sizes, specifications and dimensions as well as in custom sizes as per our customer’s demand. To ensure best quality of products we perform various tests on our products. Some of the tests are Micro Test, Macro Test, Hardness Test, Pitting Resistance Test, Intergranular Corrosion (IGC) Test, Flaring Test, and Flattening Test and so on. We are conscious of the quality of our company and with our consistent efforts to upgrade our technology we have gained the most reliable name in the market. Our products are available in customized sizes to our clients as per their requirements.
