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 254 SMO 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.

SMO 254 Slip On Flange — SMO 254 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 254 SMO Slip On Flange and SMO 254 Slip On Flange is in ready stock with Siddhagiri Metals and Tubes.

SMO 254 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. Alloy 254 SMO Blind Flange and SMO 254 Blind Flange is in ready stock with Siddhagiri Metals and Tubes.

SMO 254 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. Alloy 254 SMO Weld Neck Flange and SMO 254 Weld Neck Flange is in ready stock with Siddhagiri Metals and Tubes.

SMO 254 Socket Weld Flange — Initially developed for small high-pressure piping systems a Socket Weld Flange is similar to Slip On Flange.

Properties of Alloy 254 SMO Stainless Steel

254 SMO Cold Forming

Cold working of SMO 254 can be carried out using all the traditional methods, however the process would be tough due to its high work hardening rate. The result will provide 254 SMO with increased strength and toughness.

254 SMO Hot Forming

Forging, upsetting and other operations relating to 254 SMO can be performed at 982 - 1149°C (1800 - 2100°F). To attain maximum corrosion resistant properties, it is advisable to perform post-process annealing.

254 SMO Machining

SMO 254 is quite tough to machine due to the extremely high work hardening rate and lack of sulfur content; however using sharp tools, overpowered machine tools, positive feeds, good amount of lubrication, and slow speeds tend to provide good machining results.

254 SMO Welding

Welding of stainless steel grade 254 SMO requires filler material without which it results in poor strength properties. Filler metals such as AWS A5.14 ERNiCrMo-3, and alloy 625 are recommended. Electrodes used in the process, have to match with AWS A5.11 ENiCrMo-12.

254 SMO Heat Treatment

254 SMO does not respond to heat treatment. Hardening is possible only through cold reduction.
