General notes:
For dimensions "B" and "H" click IMPORTANT.
Blind flanges ASME B16.47 series A flanges (≥ NPS 26) are MSS SP-44 flanges.
ASME has incorporated the MSS-SP44 specification into B16.47 Series A and the API 605 Specification into B16.47 series B.These specification include only Welding Neck and Blind Flanges.
Dimensions for Classes 400, 600 and 900 NPS 38 and larger for Series A flanges are the same as for the Series B flanges.The length of the Stud Bolt does not include the height of the chamfers (points).
