The ASME B16.47 flanges refer to large diameter pipe flanges manufactured in accordance with ASME B16.47, which covers pressure-temperature ratings, materials, dimensions, tolerances, marking, and testing for the flanges. These flanges can be provided in sizes NPS 26 through NPS 60 with rating class designations 75, 150, 300, 400, 600, and 900. NPS is the designation for nominal flange size. It is related to the reference nominal diameter, DN, used in international and other standards. For flange sizes covered in ASME B16.47, the relationship is DN = 25 × NPS. The standard specification states values in both SI metric and U.S. Customary units, except that diameter of bolts and flange bolt holes are expressed in inch units only.

 

ASME B16.47 Series B specifies flange dimensions for compact flanges that, in most cases, have smaller bolt circle diameters than Series A flanges. At the request of the American Petroleum Institute (API), flange dimensions of ASME B16.47 Series B are provided in accordance with the API standard 605.

 

Materials and Manufacturing

Particularly, forged flanges, manufactured according to ASME B16.47 Series A or Series B, shall be manufactured as one piece in accordance with the applicable material specification. The forging process, either die forging or open-die forging, is a compressive plastic hot working operation that consolidates the material to flow in the direction most favorable for resisting the stresses encountered in service.
