A flange joint is a connection of pipes, where the connecting pieces have flanges by which the parts are bolted together. The principle of a flange is to apply a mechanical force by using bolts to preload the gasket until contact stress between flanges and gasket is sufficient to maintain a seal. Connection to the pipe is by welding or threading. To allow easy functionality and inter-changeability, these are designed to have standardised dimensions which include ANSI, ASME, DIN, EN, BS, JIS. Duplex Stainless Steel Flanges have major applications in Oil, Gas, Petrochemical, Ship-Building, Marine, Food, Dairy, Railways and other associated industries were piping systems are required. Duplex Steel Pipe Flanges are available in following forms:
Duplex Steel Slip On Flange — Alloy Slip-On Flanges is slightly larger than the outer diameter of the pipe it is to be used with. The pipe is slipped into the Flange prior to welding both inside and outside. We supply a wide range of slip-On Flanges in different dimensions and sizes. Duplex S31803 Slip On Flange and Duplex S32205 Slip On Flange is in ready stock with Siddhagiri Metals and Tubes.
Duplex Steel Blind Flange — Alloy Flange with no borehole are known as Blind Flange and used to close the end of the pipe. Blind Flanges are supplied as threaded or welded from class 150lb to 2500lb. Duplex S31803 Blind Flange and Duplex S32205 Blind Flange is in ready stock with Siddhagiri Metals and Tubes.
Duplex Steel Weld Neck Flange — Alloy Weld Neck Flanges are widely used in high-pressure piping systems and can be easily recognised by the long tapered hub. The size of the bore hole is usually equal to the size of the pipe. Duplex S31803 Weld Neck Flange and Duplex S32205 Weld Neck Flange is in ready stock with Siddhagiri Metals and Tubes.
Duplex Steel Socket Weld Flange — Initially developed for small high-pressure piping systems a Socket Weld Flange is similar to Slip On Flange. The flange is installed by welding around the hub of the flange. Duplex S31803 Socket Weld Flange and Duplex S32205 Socket Weld Flange is in ready stock with Siddhagiri Metals and Tubes.
Duplex Steel Threaded Flange — Threaded Flanges are used for special application where the flange can be assembled to the piping system by without welding. We specialise in all forms of threaded flanges and can supply it in multiple size range. Duplex S31803 Threaded Flange and Duplex S32205 Threaded Flange is in ready stock with Siddhagiri Metals and Tubes.
Duplex Steel Lap Joint Flange — Lap-Joint Flanges are similar to Slip-On flanges and are generally used with Lap-Joint Stubs. This type of flange is highly used where the piping systems are disassembled from time to time. Duplex S31803 Lap Joint Flange and Duplex S32205 Lap Joint Flange is in ready stock with Siddhagiri Metals and Tubes.

Properties of Duplex 2205 Steel
Duplex 2205 Cold Forming
Duplex 2205 has shown good formability in a variety of fabrications. The high strength of Duplex 2205 can pose problems. Even when the equipment has sufficient power, allowance must be made for higher spring-back caused by the grade’s high strength.
Duplex 2205 Hot Forming
2205 Duplex can be worked at maximum hot forming temperature between 2010 and 2100°F (1100 to 1150°C). If the shape of the work piece is not compact, the edges may be significantly cooler than the bulk, and there is risk of cracking in the cooler regions.
Duplex 2205 Machining
Duplex 2205 is somewhat more difficult to machine than the 300 series austenitic stainless steels. Higher cutting forces are required and more rapid tool wear is typical.
Duplex 2205 Welding
2205 Duplex possesses good weldability but Should not generally be welded without filler metal as this may result in excessive ferrite.
Duplex 2205 Heat Treatment
Annealing temperature range is 1868 to 2012°F (1020 to 1100°C). Cannot be hardened by heat treatment, but Duplex 2205 does work-harden. Special consideration is needed to compensate for a higher coefficient of thermal expansion to avoid warping and distortion.
