Stainless Steel 321 Flanges

ASTM A182 F321 Weld Neck Flange and AWWA C207/ Class 150/ 300/ 600 SS 321 Flanges manufacturer in India

The Stainless Steel 321 grade belongs to an austenitic grade that is stabilized with titanium. Stainless Steel 321 Flanges are designed with primary constituents of chromium and nickel. These flanges help in connecting different fixtures and provide excellent stability during the flow of fluids and gases in the system. The ASTM A182 F321 Weld Neck Flange is a wrought grade that is designed with a long protruding hub. These flanges help in transferring weight from the fixture allowing movement of pressurized flow in the system. Class 150 SS 321 Slip on Flanges is designed to hold and process moderate to low pressure fluids and gases. These flanges are usually welded in place using one or more fillet welds as it is directly slid on the fixture. The AISI 321 Socket Weld Flange is commonly seen in small sizes pipes that can transmit high pressures. These flanges are inserted in a socket opening and subsequently welded using a single fillet weld. The versatile DIN 1.4541 Forged Flanges possess enhanced tensile and fatigue strength. These flanges have higher ductility and possess a finer grain structure and less surface porosity. They are available in different shapes and sizes as per customer requirements.

An SA 182 Gr F321 Blind Flange is designed without any face type or a protruding hub. This allows them to completely seal the ends of the system to terminate the flow of high pressure and elevated temperature fluids and gases. The SUS 321 Spectacle Blind Flanges are robust safety devices that are nearly identical to a blind flange; however, they have an open end with a closed face end. The open end allows for easy fluid flow, while the close end is employed to terminate the flow. These flanges are common in systems where there is repair and maintenance taking place.
