Specifies the inner diameter of the flange.
Typical units (depending on your unit system):
-
in
-
mm
-
cm
For integral type flanges, this value will also be the inner pipe diameter. This value is referred to as "B" in the ASME code.
The flange inside diameter is contained in the flange database. The software looks up this value whenever you press Ctrl+ F in the Flange tab. The flange database contains properties of ANSI B16.5 and API 605 flanges.
For inside diameters not specified in B16.5, the matching ID of standard wall pipe is used. Verify this dimension based on the actual application and use of the flange. The following table shows pipe inside diameters for various nominal sizes. All sizes are shown in inches.
