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 Stainless Steel 316L Pipe 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 316L 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 316L 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 316L 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 316L Socket Weld Flange and Stainless Steel Socket Weld Flange is in ready stock with Siddhagiri Metals and Tubes.

Properties of AISI 316L Stainless Steel

316L SS Cold Forming

316/316L being extremely tough and ductile, can be easily cold worked such as roll form, swaging, cold heading, deep drawing, bent, etc. Severely cold formed parts should be annealed to remove stresses.

316L SS Hot Forming

Most manufacturers recommend a maximum forging temperature between 2100°F and 2300°F. Best Corrosion resistance is obtained if the forgings are given a final anneal.

316L SS Machining

316/316L is more difficult to machine because of its toughness. 316/316L machines with chip breakers and curlers. A large tool and great amounts of cutting fluid should be used. 316/316L work hardens rapidly thus, heavy positive feeds at low speeds should be used.

316L SS Welding

Excellent weldability by all standard fusion methods, both with and without filler metals. Heavy welded sections post-weld annealing for maximum corrosion resistance is not required for grade 316L.

316L SS Heat Treatment

Annealing temperature range is 1900 to 2100°F (1038 to 1149°C). Cannot be hardened by heat treatment. Special consideration is needed to compensate for a higher coefficient of thermal expansion to avoid warping and distortion.
