Collar Flange

A collar is essentially used to couple a flange to a pipe. They are versatile and can be used in flange assemblies to form a compact system. When they are added to piping systems, the Plain Collar Flange offers a leak-proof finish, thus preventing the escape of gases or liquid by their tight seal. Typically they are used in systems that have connections with pressed flanges. Pressed flanges are popular in industries like Oil & Gas, Purification, Chemical as well as Petrochemical because they offer fitted connections. While using pressed flanges, one needs to make use of a sealing gasket for a snug fit. To optimize the connection between piping systems, and a pressed flange a sealing gasket is added between the two DIN 11864-2 Pressed Collar Flange. Once the bolts are tightened, the gasket ensures absorption of stress from the collars. As with most flanges, the material they are made from gives them their characteristics. The preference for Stainless Steel Collar Flange in both grades 304 and 316 is more because they offer better mechanical properties, and moderate to good resistance to corrosion. Though grade 316, exhibits better corrosion resistance behavior in comparison to grade 304.
