ASTM B564 UNS N04400 • Monel 400 Flanges • Monel Flanges • Alloy 400 Flanges Supplier

Siddhagiri Metals and Tubes supplies a comprehensive range of Monel 400 Flanges maufactured as per ASTM B564 in PN 6, PN 10, PN 16, PN 25, PN 40, PN 64 upto PN 160 Pressure Ratings. These Alloy 400 Flanges are available in all forms. Monel Flanges are mainly used in high-temperature, seawater and acidic environments.

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 ASTM B564 Flanges are designed to have standardised dimensions which include ANSI, ASME, DIN, EN, BS, JIS. Flanges have major applications in Oil, Gas, Petrochemical, Ship-Building, Marine, Food, Dairy, Railways and other associated industries were piping systems are required.

Monel 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.

Monel 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.

Monel 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.

Monel 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.

Monel 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.

Monel 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.

Siddhagiri Metals and Tubes supplies Monel Flanges in different sizes and pressure ratings.

Properties of Monel 400 alloy

Alloy 400 Cold Forming

Alloy 400 displays excellent cold forming characteristics. Soft Die materials can be used for a better finish.

Alloy 400 Hot Forming

Alloy 400 can be hot-formed into any shape. The Hot working temperature range for this alloy must be between 648-1176°C (1200-2150°F).

Alloy 400 Machining

Alloy 400 can be machined at satisfactory rates with machine tools generally used for iron alloys.

Alloy 400 Welding

Welding Methods for Alloy 400 is similar to austenitic stainless steels. Alloy 400 can easily be joined by gas-tungsten arc, gas metal arc or shielded metal arc processes using appropriate filler metals.

Alloy 400 Heat Treatment

Heat treatment for alloy 400 should be done in a sulfur-free environment. Annealing cycle for alloy 400 should range from 1300 to 1800°F, however, 1600 to 1800°F is most typical.
