Face finish: The finish on the face of flange is measured as an Arithmetical Average Roughness Height(AARH). The finish is determined by the standard used. For example, ANSI B16.5 specifies face finishes within a range 125AARH-500AARH(3.2Ra to 12.5Ra). Other...
A flange face may be smooth or serrated, but additional machining steps can be taken to further define the exact finish of each type of surface. For example, a flange surface may be smooth, but how smooth? A serrated flange surface has serrations, but what is the depth, number, and ...
Flange “finish” refers to the type of surface produced by matching theflange face, which contacts the gasket. The two types of finish are “smooth” and “serrated.” Raised face forged steel flanges are machined to provide a “serrated concentric” groove, or a “serrated spiral” groove ...

Spiral Serrated: 125 to 250 AARH: This finish is produced with a continuous spiral groove but utilizes a 90° included angle “V” tool. The groove is 1/64” deep and the feed is 1/32” for all sizes. 3. Concentric Serrated: 125 to 250 AARH: This finish is produced with concentric...
