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. Nickel Alloy 20 Flanges have major applications in Oil, Gas, Petrochemical, Ship-Building, Marine, Food, Dairy, Railways and other associated industries were piping systems are required. Nickel Alloy Pipe Flanges are available in following forms:

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. Alloy 20 Slip On Flange, Carpenter 20 Slip On Flange and Incoloy 20 Slip On Flange is in ready stock with Siddhagiri Metals and Tubes.

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. Alloy 20 Blind Flange, Carpenter 20 Blind Flange and Incoloy 20 Blind Flange is in ready stock with Siddhagiri Metals and Tubes.

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. Alloy 20 Weld Neck Flange, Carpenter 20 Weld Neck Flange and Incoloy 20 Weld Neck Flange is in ready stock with Siddhagiri Metals and Tubes.

Socket Weld Flange — Initially developed for small high-pressure piping systems a Socket Weld Flange is similar to Socket Weld Flange. The flange is installed by welding around the hub of the flange. Alloy 20 Socket Weld Flange, Carpenter 20 Socket Weld Flange and Incoloy 20 Socket Weld Flange is in ready stock with Siddhagiri Metals and Tubes.

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. Alloy 20 Threaded Flange, Carpenter 20 Threaded Flange and Incoloy 20 Threaded Flange is in ready stock with Siddhagiri Metals and Tubes.

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. Alloy 20 Lap Joint Flange, Carpenter 20 Lap Joint Flange and Incoloy 20 Lap Joint Flange is in ready stock with Siddhagiri Metals and Tubes.

Properties of Alloy 20

Alloy 20 Cold Forming

Alloy 20 can be readily hot-formed to practically any shape. The recommended temperature range for hot forming is 1200° to 2250°F (650° to 1230°C).

Alloy 20 Hot Forming

Alloy 20 can be worked by all conventional cold-forming methods. Severe work can be done manually only with the assistance of frequent anneals to restore softness.

Alloy 20 Machining

Alloy 20 can be machined satisfactorily at commercial rates provided proper machining practices are carefully followed.

Alloy 20 Pipe Welding

Alloy 20 can be welded by conventional welding, brazing and soldering processes. Good properties are inherent in these joints. Cleanliness and removal of foreign material are important in attaining sound welds.

Alloy 20 Heat Treatment

Alloy 20 is non hardenable by heat treatment.
