Selection notes
The blind flange center island must match the mating flange.
The standard edition shown in the title identifies this dimensional table. Include the required project edition in the RFQ.
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.
