Flange Dimensions

Look up ASME B16.5 / B16.47 flange dimensions by pressure class and size

Flange Dimensions

Look up flange dimensions by pressure class and nominal size. The library covers ASME B16.5 (NPS ½ to 24) and ASME B16.47 Series A large-diameter flanges (NPS 26 to 60).

For each Class (150 to 2500) and NPS, get:

• Flange outside diameter
• Bolt circle diameter
• Number and size of bolts
• Bolt hole diameter
• Flange thickness for blind, slip-on, and welding-neck types

Three ways to find a flange:

• Nominal size — search by size.
• Pressure class — pick a Class.
• Threshold filter — set a minimum outside diameter.

Values in both mm and inch.
