Duplex 2205 Flanges are available in a wide range of pressure ratings and sizes, to meet the specific requirements of precise projects that call for the use of such types of flanges. Duplex flange have high energy absorption and low thermal expansion. Duplex 2205 are available in a wide variety of flanges such as lap joint flanges, reducing flanges, orifice flanges, slip-on flanges, blind flanges, threaded flanges, weld neck flanges and socket weld flanges. Flanges made from Duplex 2205 exhibit very high resistance to pitting and crevice corrosion, as well as to chloride stress corrosion cracking, plus they also show excellent resistance to sulfide stress corrosion. Flanges that are made from Duplex 2205 have good fatigue resistance and they also have high strength. Duplex 2205 Flanges are manufactured from austenitic-ferritic stainless steel and so they are in big demand all over the world, in various kinds of applications, as they are not only resistant to corrosion, but they also deliver higher strength. Because of their special characteristics, Super Duplex 2507 Flanges have been designed for use in conditions where there is a need for their high strength.
Duplex 2507 flanges are used in the following sectors: water desalinization, chemical, power, petrochemical, marine, oil and gas production and pulp and paper. The Chemical Composition of Super Duplex 2507 is Chromium, Cr 24 – 26, Nickel, Ni 6 – 8, Molybdenum, Mo 3 – 5, Manganese, Mn 1.20 max, Silicon, Si 0.80 max, Copper, Cu 0.50 max, Nitrogen, N 0.24 – 0.32, Phosphorous, P 0.035 max, Carbon, C 0.030 max, Sulfur, S 0.020 max and Iron, Fe balance. Flanges made from Super Duplex 2507 are designed specifically for use in applications which call for the need of exceptional strength and corrosion resistance, such as petrochemical processes, seawater equipment and chemical processing.Super Duplex 2507 Flanges are specifically used in areas where the corrosive conditions are extremely high.
