Stainless Steel 321 Flanges

Stainless Steel 321 Flanges

Refer ASTM A182 F321 Pipe Flange Dimension and Pressure Ratings, Asia's leading manufacturers and suppliers of SS 321 Weld Neck Flange

A flange is a flat rim or collar that serves as a strengthening agent that allows them to connect to different piping equipment. The Stainless Steel 321 Flanges are chromium and nickel alloys that are stabilized with titanium. These flanges are tolerant to sensitization against intergranular corrosion. SS DIN 1.4541 Forged Flanges are processed at extreme temperatures and pressures. These flanges have lower surface porosity and a density of 8027 kg/m3. The SA182 F321 Plate Flanges are flat circular discs that can be easily welded on the pipe and can be bolted to another pipe. These flanges have exceptional mechanical properties and work well across different environments.

Stainless Steel 321 Weld Neck Flanges are recognized by a long protruding hub or face. These flanges help remove stress from the pipe and are usually seen in applications where repeated bending is taking place. The 321 Stainless Steel Blind Flanges don’t possess a boring center or a hub. These flanges act as blanks that allow them to terminate the flow of media in the system. AISI 321 Spectacle Blinds are similar to blinds; however, they have two openings. One end is blank and the other is an open end, allowing room for the normal flow of media in the system. ASTM A182 F321 Slip On Flanges are amongst the most common type of flanges that are slid easily on the pipe and welded using fillet welds. The flanges are recommended for use across moderate to low pressure setups. The UNS S32100 Lap Joint Flange is made with a two components assembly consisting of a stub end with a ring-type sealing. These flanges have the freedom to swivel around and facilitate the lining up of bolt holes. An SS 321 Socket Weld Flange is generally seen in smaller sizes pipes for lower pressure applications. They have similar strength as slip on flanges but possess better fatigue strength. The SUS 321 Threaded Flange is designed possessing threads that allow them to align easily with subsequent grades. These flanges are easy to install, and they don’t require a welding process to join them.
