stainless steel 316L flanges

A 316L flange is a low-carbon austenitic grade steel used to produce strong flanges. The Stainless Steel 316L Flanges are designed with a superior chemical content of chromium, nickel, and molybdenum with other constituting alloys. These flanges are used to connect piping equipment efficiently, allowing room for repair and maintenance. The 316L Stainless Steel Flanges provide stability to different applications as there is a movement of media in the system. These flanges have enhanced resistance to pitting by acids and general corrosion. ASTM A182 F316L is a forged alloy grade that has enhanced strength and load-carrying capacity. They have a lower surface porosity with a good grain structure. 

The SS 316L Blind Flange is manufactured without a protruding hub or a face. These flanges are utilized to terminate the flow of media across stress-induced conditions. An EN 1.4404 Blind Flange can be welded but is generally bolted in place allowing room for repair and maintenance in the system. The ASTM A182 F316L Slip On Flange has a low profile grade that is slid on the piping equipment and is welded in place using fillet welds. These flanges are preferred by engineers as they are cheap, but they are seen in applications where stress on the system is less. A SA 182 Gr F316L Weld Neck Flange is seen in elevated pressure and high temperatures. These flanges possess superior strength due to the long tapered face giving them enhanced stability in treacherous conditions. The 316L Stainless Steel Lap Joint Flange has a two-component assembly that has a stub end with a ring face used to align it in place. The flange type is utilized in connecting flanges that are large and difficult to adjust. Stainless Steel 316L Socket Weld Flange is typically seen in smaller sizes of low-pressure pipe grades. The flange has a recessed area that allows it to be attached and welded using a single fillet weld.
