Pressure Relief Valve Detail

Notes:

1. This gure conforms with the requirements of section VIII of the ASME Boiler and Unred Pressure Vessel Code for MAWPs greater than 30 psi.
2. The pressure conditions shown are for pressure relief valves installed on a pressure vessel.
3. Allowable set-pressure tolerances will be in accordance with the applicable codes.
4. The maximum allowable working pressure is equal to or greater than the design pressure for a coincident design temperature.
5. The operating pressure may be higher or lower than 90
6. Section VIII, Division 1, Appendix M of the ASME Code should be referred to for guidance on blowdown and pressure differentials.
