Notes:

ASME B16.47 Series A flanges (> NPS 26) are MMS SP-44 flanges. MSS SP-44 also covers NPS 12 to NPS 24 flanges which are equivalent to ASME B16.5. MSS SP-44 is the only source for the NPS 22 flange dimensions above.
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.
