Notes:

  • ASME B16.47 Series B flanges are API 605 flanges. API 605 has been cancelled.
  • Dimension B is to be specified by the purchaser. It corresponds to the pipe inside diameter.
  • Flat face flanges may be provided at full thickness, C, or with raised face removed (the latter is nonstandard).
  • WNF = Weld Neck Flange.
  • The large end of the hub may be straight or tapered.
