HGFF GROUP is privately owned Carbon Steel and Stainless Steel Raised Face Flange Manufacturers in China, manufacture with Pressure Classes 150 and 300, the height of the raised face is approximately 1.6 mm (1/16 inch). In these two Pressure Classes, almost all suppliers of raised face flanges, show in their catalog or brochure, the H and B dimensions including the raised face height. These ASME B16.5 Raised Face flanges normally come in slip-on and weld neck. Class 300 Raised Face Flanges has a small portion around the bore is raised from the face. This type of raised face flange height depends on the flange pressure-temperature rating that is known as a class of the flange. For 150# Raised Face Flange & 300# Raised Face Flange height is 1/6” and above 300# it is 1/4”. The inside bore circle type of gasket is used with a raised face flange.
