Safety Valve Design Procedure guidelines

Design Procedure


General procedure in the design of protection against overpressure as below,

(i) Consideration of contingencies: all condition which will result in process equipment overpressure is considered; the resulting overpressure is evaluated and the
appropriately increased design pressure;  and each possibility should be analyzed
and the relief flow determined for the worse case.


(ii) Selection of pressure relief device: the appropriate type for pressure relief device for each item of equipment should be proper selection based on the service required.
(iii) Pressure relief device specification:  standard calculation procedures for each type of pressure relief device should be applied to determine the size of the specific
pressure relief device.

 
(iv) Pressure relief device installation:  installation of the pressure relief valve should be at the correct location, used the correct  size of inlet and outlet piping, and with
valves and drainage
