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 317L 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 317L 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 317L 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 317L 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 317L 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 317L 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.

Properties of AISI 317L Stainless Steel
317L SS Cold Forming
SS 317L is quite ductile and forms easily. The addition of molybdenum and nitrogen implies more powerful processing equipment may be necessary when compared with the standard 304/304L grades.
317L SS Hot Forming
Working temperatures of 1652 – 2102°F (900 – 1150°C) are recommended for hot working processes. Do not work this SS below 1742°F (950°C). If the final forming temperature falls below this threshold, a solution anneal of 1976 – 2156°F (1080 – 1180°C) is necessary. Rapid quenching is required.
317L SS Machining
The cold work hardening rate of SS 317L makes it less machinable than 410. Low speeds and constant feeds will minimize this SS's tendency to work harden. Tougher than 304 stainless with a long stringy chip, the use of chip breakers is recommended.
317L SS Welding
SS 317L can be readily welded by most standard processes. A post weld heat treatment is not necessary. All common fusion and resistance methods except oxyacetylene welding have proven successful. Use AWS E/ER 317L filler metal for best results.
317L SS Heat Treatment
317L stainless steel does not respond to heat treatment. Cold work will cause an increase in both hardness and strength. 1850-2050 F (1010-1121 C), followed by rapid cooling.
