Dear Experts,
I wonder if the below question have a cross your mind.
Our tank is designed as per Appendix F with 1.5 PSI design pressure.
The air test pressure is 1.25 x 1.5 = 1.875 psi.
Our atmospheric is about 1 ATM or about 14.5 PSI.
Does this mean the pressure outside the tank is bigger than inside the tank ? Why we need to air test while the pressure outside the tank is bigger than inside the tank ?
