Flange surface finish roughness for cnaf
WebA serrated finish, either concentric or spiral, is required with 30 to 55 grooves per inch and a resultant roughness between 125 and 500 microinches. This allows for various grades of surface finish to be made available by flange manufactures for the gasket contact surface of metal flanges. WebSurface roughness is commonly measured or classified as Ra (Roughness average) or Rq (the equivalent of RMS — Root Mean Square). Both are measured in microinches and denote the smoothness of ground or machined surfaces. For comparison, an Ra reading is approximately 87.5 percent of an Rq (RMS) reading.
