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.

-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.

-Class 400 Series A dimensions at NPS 38 and larger also apply to Class 400 Series B flanges.

-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 + raised face, or with raised face removed (the latter is nonstandard).

-WNF = Weld Neck Flange.

-The large end of the hub may be straight or tapered.

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.

-Class 600 Series A dimensions at NPS 38 and larger also apply to Class 600 Series B flanges.

-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 + raised face, or with raised face removed (the latter is nonstandard).

-WNF = Weld Neck Flange.

-The large end of the hub may be straight or tapered.
