AISI 347H Stainless Steel Pipe Flanges Supplier • ASTM A182 F347H • Stainless Steel Flanges
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 A182 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.
Stainless Steel Slip On Flange — Stainless Steel 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. SS 347H Slip On Flange and Stainless Steel Slip On Flange is in ready stock with Siddhagiri Metals and Tubes.
Stainless Steel Blind Flange — Stainless 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. SS 347H Blind Flange and Stainless Steel Blind Flange is in ready stock with Siddhagiri Metals and Tubes.
Stainless Steel Weld Neck Flange — Stainless 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. SS 347H Weld Neck Flange and Stainless Steel Weld Neck Flange is in ready stock with Siddhagiri Metals and Tubes.
Stainless 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. SS 347H Socket Weld Flange and Stainless Steel Socket Weld Flange is in ready stock with Siddhagiri Metals and Tubes.
Stainless 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. SS 347H Threaded Flange and Stainless Steel Threaded Flange is in ready stock with Siddhagiri Metals and Tubes.
Stainless 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. SS 347H Lap Joint Flange and Stainless Steel Lap Joint Flange is in ready stock with Siddhagiri Metals and Tubes.
