Published ASME B16.47 Series A dimensions for every Class 400 size in this product family.
Dimensions in millimetres; the inch equivalent is shown in brackets. Bolt hole diameter applies to through-holes. For stud length, gasket and bolting selection, match the gasket and bolts to B16.47 A.
What Class 400 means in service
Series A follows the former MSS SP-44 dimensions. Ratings are ASME classes 150, 300, 400, 600 and 900, with allowable pressures read from the B16.47 pressure–temperature tables for the material group and design temperature.
