API 620 Vs API 653
API 620 Vs API 653
(OP)
A refrigerated Butane storage tank is fabricated as per API 620.
Now repair is required to replace the some of the shell portions. Is API 653 correct standard to follow the repair procedure? API 653 states that it is for tanks fabricated to API 650.
If API 653 is not correct standard then which standard is to be followed
Any help will be greatly appreciated
Thanks

RE: API 620 Vs API 653
This is given in paragraph 1.2.2 (= scope) of API -579
****************
It is expected that API 653, and the other inspection/derating/ repair ones ( I believe API 510 and 570 ??) for vessels and piping will be obsolete ..who knows..
My personal opinion.

The tank is flat bottom cylindrical tank with conical roof

Although API-653 was written primarily for API650 and 12C tanks, it may be applied to any tank constructed to a recognized tank standard. However, little guidance is offered for doing so. I'd like to invite you to visit our website and leave a message. We have performed several inspections on low temperature storage tanks built to API-620 using the principles of API-653 as a guide.
