Notes:
ASME 816.47 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 816.5. MSS SP-44 is the only source for the NPS 22 flange dimensions above.
Dimension 8 is to be specified by the purchaser.
Flat face flanges may be provided at full thickness, C, or with raised face removed (the latter is non-standard).
WNF= Weld neck flange
The large end of the hub may be tapered or straight.
