API vs STI for ASME Coded Vessel

[mp08]

We have a storage tank with flammables that was built to ASME Section 8/pressure vessel code. We're trying to determine if we should be using API 653 or STI SP001. I know API is more strict, but all of the other tanks at our site are inspected to STI standard. Any suggestions?

Although you define storage tank ,is this a storage tank or pressure vessel?. Pls provide more details (pressure, content, dimensions of the tank..) and pls post this thread at storage tank forum to get more helpful responds.

Depending on the tank size or service, either STI or API codes may be applicable to the tank inspection.
