Flange Face. There are various face configurations for flanges. Typically: flat face,raised face, tongue and groove, ring joint.
Face Finish. The finish on the face of a flange is measured as an Arithmetical Average Roughness Height (AARH). The finish is determined by thestandard used. For example, ANSI B16.5 specifies face finishes within a range 125AARH -500AARH (3.2Ra to 12.5Ra). Other finishes areavailable on request, for example 1.6Ra max,1.6/3.2Ra, 3.2/6.3Ra or 6.3/12.5Ra.
