Refer Price list and Dimensions of SAF 2205 Slip on Flanges, Biggest Duplex 2205 Flanges Manufacturer in India

Duplex steel is designed with a ferritic and austenitic microstructure. The Duplex Steel Flanges are designed with a chemical composition consisting of carbon, manganese, silicon, phosphorous, sulfur chromium, molybdenum, nickel, and nitrogen. This content gives these flanges excellent corrosion and oxidation resistance properties across a wide spectrum of stress-induced setups. A Duplex SS Flange has outstanding resistance to pitting and crevice corrosion in the system. These flanges have twice the strength of normal austenitic grades of steel. They offer enhanced workability and weldability in the system. Duplex Stainless Steel Flanges have a higher erosion fatigue strength and work well in temperatures in the range of -50 degrees F to 600 degrees F. The flanges working outside this range may have certain restrictions, especially for welded structures. The Duplex 2205 Flanges are designed with a density of 7.8 g/cm3 and have enhanced mechanical properties. These flanges have a minimum tensile strength of 621mpa with a minimum yield strength of 448mpa and can be elongated by 25% in the system. These flanges have a hardness of 293max HB and have a thermal conductivity of 19 at 100 degrees C.

The SAF 2205 Slip on Flanges is one of the most popular flanges in this range. They are easily slid on the pipe fixture and can be welded to the module using one or two fillet welds. These flanges are preferred in moderate to low pressure and temperature applications. A Duplex Blind Flange doesn’t have a face type or a boring center. They seal the components to the end of hydraulic systems and are generally bolted. This allows room for inspection and repair in the system. The UNS S31803 Threaded flanges are designed with threads that allow them to be aligned and joined to the subsequent modules without the need for any welds.
