Check Dimension of Duplex 2205 Stainless Steel Flanges, Manufacturer of UNS S31803 / S32205 Weld Neck Flange
Duplex 2205 Flanges are made up of a dual nature steel that has austenitic and ferritic microstructures in its metallurgy. The material is corrosion resistant to chloride stress. It is used at corrosive environments. Roopam Steel produces flanges in 2205 material and supply them in large quantities. The Class 150 Duplex S31803 Flanges are one of the low pressure variations of the flanges. There are classes ranging from 150 to 2500 and PN6 through PN64 in 2205 flanges. We are leading Duplex 2205 Flanges Supplier in India. The classes correspond to the pressure capacities of the flanges. The different varieties of the flanges include the Duplex UNS S32205 Orifice Flange which is the most commonly used duplex orifice flange. The applications of the flanges vary based on the requirement. The ANSI B16.5 UNS S31803 Duplex Steel Blind Flange is used to close a pipe and it ranges from ½ inches to 48 inches in nominal bore size as determined by the standard.

Duplex Stainless Steel Flanges

UNS S31803 / S32205 Weld Neck Flange
Superior pitting and crevice corrosion resistance Class 150 Duplex S31803 Flanges, Refer Pressure Rating of Duplex SAF 2205 Flanges
The ASTM A182 Duplex S31803 Slip On Flanges are used for high pressure vessels and high pressure applications. The operating temperature ranges up to 150 degrees Celsius in chloride rich environments. There are welded, bolted and threaded flanges in this material grade. The Duplex Steel Werkstoff No 1.4462 Threaded Flanges are used where welding is not preferred. There are different types such as the Duplex SAF 2205 Socket Weld Flanges which use a socked welded onto them for strength. The material is strong with 621MPa minimum tensile strength and 448MPa minimum yield strength. To increase the surface for connection, the Duplex Steel S31803/S32205 RTJ Flange is used. It is applied in two halves as a pair. We also supply other types such as the 2205 Duplex Weld Neck Flange. Please contact us for your 2205 flange needs.
