Selection notes
Facing in this dimensional series: 1/16 in raised face (RF).
A flat face (FF) can be specified with the inquiry.
Confirm the bore against the required pipe schedule and wall thickness.
Class designations are not direct pressure values. Confirm material grade, temperature, facing and the applicable standard edition before ordering.
Specify your flange.
Send the standard, class, size, material and quantity. Add a drawing for custom requirements.
