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 904L 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 904L Slip On Flange — Stainless Steel 904L 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. AISI 904L Slip On Flange and 904L Stainless Steel Slip On Flange is in ready stock with Siddhagiri Metals and Tubes.
Stainless Steel 904L Blind Flange — Stainless Steel 904L Flange with no borehole are known as Blind Flange and used to close the end of the pipe.

Properties of AISI 904L Stainless Steel
904L SS Cold Forming
904LSS is quite ductile and forms easily. Cold working operations will increase the strength and hardness of the alloy and might leave it slightly magnetic.
904L SS Hot Forming
Working temperatures of 1700 – 2200°F (927 – 1204°C) are recommended for most hot working processes. For maximum corrosion resistance, the alloy should be annealed at 1900°F (1038°C) minimum and water quenched or rapidly cooled by other means.
904L SS Machining
Stainless Steel 904L is subject to work hardening during deformation and is subject to chip breaking. The best machining results are achieved with slower speeds, heavier feeds, excellent lubrication, sharp tooling and powerful rigid equipment.
904L SS Welding
SS 904L can be readily welded by most standard processes. A post weld heat treatment is not necessary.
904L SS Heat Treatment
904L stainless steel cannot be hardened by heat treatment. Solution treatment or annealing can be done by rapid cooling after heating to 1010-1120°C.
