>>Flange is specified with the following details:
1) Type and Facing: i.e. whether the flange is for example “Weld Neck, RTJ” or “Socket Weld, RF”.
2) Nominal Pipe Size: required for all flanges, usually in inches.
3) Flange Pressure Class: required for all flanges, e.g. Class 150, 300, 900, 1500, 2500 etc.
4) Standard: ANSI B16.5, BS 1560, API 6A, API 605 ,ASME B16.47.
5) Material: A material specification must be stated and will be as quoted in the piping specification.
6) Pipe Schedule: only for Weld Neck, Socket Weld, Composite Lap Joint and Swivel Ring flanges where the flange bore must match that of the pipe, e.g. Schedule 10, 30, 40, ,80, 120, 160, etc.
