Vacuum relielf Valves
Vacuum relielf Valves
(OP)
Dear,
I am working in a cryogenic ethylene tank turnaround. The vacuum relief valves are set to open at -20 mmH20 and during manteinance they were calibrated at -28 mmH20, my question is: is there any problem with the set pressure? is the integrity of the tank at risk because of the new set pressure?
What would you recommend?
Any help?
Thanks

Do you mean mmHg? rather than mmH2O

Inner tank: 1000 mmH20
