Stainless Steel Socket Weld Flanges

GNEE steel is a well-known organization for manufacturing stainless steel socket weld flanges. We also supply these flanges. Our company manufacture these flanges using SS. We provide customers with various brands, types, and characteristics of flanges. Our company is able to supply a various range of flanges from stock to fulfill the customer need. Our company produces stainless steel socket weld flanges has high resistance to corrosion. These socket weld flanges do oppose to oxidation. These flanges contain high chromium and nickel contents. Our stainless steel socket weld flanges are suitable for high-temperature applications. Our flanges exhibit good high temperature characteristics, such as excellent weldability and good ductility. According to the mechanical properties and chemical composition of the material, stainless steel has different qualities. Stainless steel contains low carbon.

Stainless Steel Socket Weld Fittings are family members of high pressure pipe fittings, which available in rating of Class 3000lb, 6000lb and 9000lb. They are used in areas where pipe-work is permanent and are designed to provide good flow characteristics. Usually in conjunction with with ASME Pipe and are available in the same size range.

Our stainless steel socket weld flanges can further be customized in terms of thicknesses, sizes and specifications as per the specific requirements of our clients. We offer these flanges at market leading prices.
