Specifies an outer diameter for a flange face or lap joint.

Typical units (depending on your unit system):

  • in

  • mm

  • cm

For all except lap joints

The outer diameter of the flange face. The software uses the minimum of the flange face outer diameter and the gasket outer diameter to calculate the outside flange contact point but uses the maximum in design when selecting the bolt circle. This is done so that the bolts do not interfere with the gasket. The software uses the maximum of the flange face ID and the gasket ID to calculate the inside contact point of the gasket. This value is required for calculating the contact gasket width and the effective gasket diameter, G.

For lap joints

The lap joint contact outer diameter. This is usually the flange face outer diameter. For additional details, see ASME Section VIII, Division 1, Appendix 2, Figure 2-4, Sketches 1 and 1A.
