WebThe roughness of a flange face is measured by the Roughness Average (Ra). Units of Ra are micro inches (µin), or micrometres (µm). Roughness is calculated using the Arithmetic Average Roughness Height (AARH), or Root Mean Square (rms) calculations. Both AARH and rms yield roughly the same result, and the two terms are often used interchangeably. WebA 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. This allows for various grades …
