API 2000 vent activation pressure
API 2000 vent activation pressure
(OP)
When sizing API 2000 vents for a small anchored tank with a relatively high fill rate we have chosen vents that require 4 to 5 inches of water delta pressure to flow the required amounts. This is higher than the weight of the cone roof plates. Other than checking Appendix F are there any other considerations?





RE: API 2000 vent activation pressure
For a small tank,4 to 5 inches of water is modest, but I would not hesitate to try to contact the original tank fabricator.
Ask him if a "standard air test" (1-2 psig) was performed on all tanks of your vintage.

Do you also have emergency venting? If so, can the emergency and regular vents be combined for the pressure case (assuming you don't also have large outflows)?

Is that CFM? Or SCFH?
If the tank isn't built yet, possibly go to a self-supporting cone roof designed for higher pressure specifically for this reason.
