Dimensions are in inches. Weights are in pounds.

(1)- Bolt lenghts are calculated based on bolting one WN to one Blind. 
(2)- Bolt diameter should be 1/8" less than the bolt hole diameter

Note : -ASME B16.47 Series A Flanges 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.
- For ring joint facings. For weld end bevel.
- For tolerances .
