Continental Disc’s rupture disc and pressure relief valve combination capacity factors were determined by testing the rupture disc device mounted directly beneath the valve inlet in accordance with ASME Pressure Vessel Code, Section VIII, Division I, and certified by The National Board of Boiler and Pressure Vessel Inspectors. The information provided is to be used as a multiplier to make appropriate changes in the ASME rated relieving capacity of the pressure relief valve. It is applicable only to the combination of pressure relief valve and rupture disc designs tested.
ASME allows the use of a 0.9 multiplier for those combinations not tested. Capacity factors are not applied to rupture discs installed at the outlet of a pressure relief valve. Continental Disc Corporation maintains an ASME accepted flow lab for conducting flow tests of rupture discs, pressure relief valves, and rupture disc / pressure relief valve combinations.
