Leading Alloy 2205 Slip on Flange Manufacturer in India, Call us to get exclusive offer of UNS S31803 Weld Neck Flanges

Duplex Flanges

A flange is a channel that helps in connecting and transporting steam and fluids in the gas and refineries to different places. The Duplex Flanges are designed with dual-certified austenitic and ferritic microstructure. These flange have a good composition of chromium, nickel, molybdenum, and nitrogen, allowing them to possess enhanced resistance to reducing and corrosive media. Duplex Stainless Steel Flanges have excellent strength with good impact toughness. These flange provide stability to different pipes during the movement of the flow in the system. The Duplex Steel Flanges are easy to install and can be readily modified and inspected. The flange can be readily bolted and welded following standard procedures. A UNS S32205 Flange has a density of 7800 kg/m3 and has enhanced mechanical properties. These flange possess a hardness of 293 max HB Brinell. The ASTM A182 F51 Flange covers forged or rolled alloy that has good resistance to pitting, stress, and crevice corrosion across harsh environments.

The Alloy 2205 Slip on Flange is a common flange in the industry as they are slid on the pipe and welded using one or more fillet welds. These flange are seen in applications where stress on the system is low. A DIN 1.4462 Socket Weld Flange has a similar strength to a slip on flange and is connected using a single fillet weld. These flange are seen in small bore-size pipes and are not preferred in certain applications where corrosion is high. The UNS S31803 Weld Neck Flanges have a long protruded hub that allows them to work in high-pressure conditions. These flange are recommended in applications where repeated bending is taking place in the system. ASTM A 182 Gr F51 RTJ Flange has grooves cut on its face, allowing them to be sealed with bolts and gaskets. They are seen in higher temperature conditions up to 800 degrees F.
