Definition and details of Flange Face Finish / Flanges

The ASME B16.5 code requires that the flange face (raised face and flat face) has a specific roughness to ensure that this surface be compatible with the gasket and provide a high quality seal.A serrated finish,either concentric or spiral,is required with 30 to 55 grooves per inch and a resultant roughness between 125 and 500 micro inches.Difference between Ring Type Joint and Raised FaceAug 29,2018·These are more commonly used in applications where either high pressure or high temperature is an issue.These are Class 600 or more flanges or where temperatures typically exceed 427° Centigrade.These flanges can be identified because theyFlange Basics Functions,Designs,and Other Raised Face (RF) These flanges feature a small raised section around the bore with an inside bore circle gasket.Ring Joint Face (RTJ) Used in high-pressure and high-temperature processes,this face type features a groove in which a metal gasket sits to maintain the seal.
