Setting PV and EV HELP
Setting PV and EV HELP
(OP)
Dear Community,
I would like to ask a question about Emergency Relief Valve & Pressure/Vacuum Relief.
Following API-650 appendix F, I calculated a max design pressure of 9,6 kPa. I suppose I’ll have to limit our PV at 9,6 kPa or less.
But, I do not want to use anchorage, and if I use this limit, I’ll have to use it. So, calculating the overturning stability, I found that an internal pressure of 3 kPa is enough to avoid anchorage.
According to the information above, am I correct to request our VALVE SUPPLIER to specify PV limit at 3 kPa and EV limit at 9,6 kPa?
Thanks in advance,
Luiz
