API 650 Allowable Overpressure? - Storage tank

A search of posts here turns up "For API 650 tanks, overpressure must not exceed MAWP of the tank. That means the set point should be lower than the Design pressure." but I couldn't find that in 650 or in API 2000. The only thing I find in 650 is Appendix F, and 2000 refers you back to the applicable tank design code. Thanks very much in api 650 tank roof ast forumAPI 650 Flat Roof Design - Eng-Tips Engineering ForumsAPI 650 is mostly concerned with the integrity of the tank.

Jul 31, 2005 · API-650 gives a set of criteria for frangibility that may be useful to you. Usually a tank needs to be well above 50 ft in diameter to be frangibile.
