Max vacuum allowable for tank & PV-vent
Max vacuum allowable for tank & PV-vent
(OP)
Hi
anyone can give me this valeu and fonts:
Max vacuum allowable for tank (fixed roof & PV-vent)
I have a PV-vent that open at -0.22 kPa
its full open is -0.242 kPa
i remember that a tank resists to -0.25 kPa but a think it can reach -0.35

Appendix V allows design of max external presusre to go up to 6.9kPa, but this would be stated on your tank nameplate, which all tanks shold have if you look closely enough somewher eon the lower shell. Max internal pressure is set by the weight and type of the roof up to a certain maximum.

Also: There's usually a good reason why everyone does it that way

For internal pressure, there is no safe default value.
