I have a pipe line of liquid where a relief valve is installed with a set pressure of 3.5 barg. The design pressure of the pipe is 20 barg. If I take overpresssure factor of 10% then the allowable overpressure (%) becomes 528.57%. Is it acceptable??
Calculation: 20 barg x 1.1 =22 barg
allowable overpressure = 22 - 3.5 =18.5
in % = (18.5/3.5)x100%=528.57%
Would be very grateful for getting any suggestion.
