The Raised Face flange is the most common type used in process plant applications. This design features gasket surfaces raised above the bolting circle face, allowing for versatile gasket combinations including flat ring sheet types and metallic composites like spiral wound and double jacketed types.
This configuration concentrates pressure on a smaller gasket area, significantly enhancing the pressure containment capability of the joint. The diameter and height specifications are determined by pressure class and diameter requirements.
