pressure relief valve for daily temp variations?
(OP)
I am working as the client in Africa on a number of petroleum storage facilities. A typical facility consists of 5 by 200m3 jet A1 tanks built in a row with a issue line connecting them at the back and a receipt line at the front. The issue and receipt lines are typically 40m long subdivided into 3 sections by gate valves. The independant engineer claims that we need pressure relief valves for the thermal effects during the day while the supplier claims we do not. I would tend to agree with the supplier as the max pressure from the tanks is 80kPa and these are thick 3 inch pipes that have been pressure tested to 15 bar. I would like to get a third opinion though.

Yes, sun shine on a blocked in line will cause an over pressure, but the check valve will open and let 3 cc's out dropping the pressure.
