Legs on API tanks

[clp]

Would someone please verify if the following is true (I believe it is but I am starting to doubt myself and need to hear it from someone else.)

API-650 is for flat bottom tanks only - is this true?
If an API tank has legs it would be an API-620 tank not 650 - true?

one more question....can an API "code" tank be made up of multiple codes? I have a customer who wants a mix of codes but still wants it stamped....is that allowable?

thank you in advance for your clarification to the above.

An API tank on legs? Not API-650, it's for flat bottom tanks only. API-620 may be used for tanks on legs. You may not mix-and-match Codes for a tank if you intend to put an API nameplate on the finished tank. It should be either all API-650 or all API-620. By contrast, you may pick and choose the appropriate Codes sections when providing a tank as non-Code.

clp,

One other option that you may consider.....

Many process engineering organizations specify smaller, vertical axis tanks (operating under 15 psig) to be designed, constucted, inspected and tested to ASME-VIII....but not ASME Code stamped.

Heads on these tanks are typically, F&D or ellipsodal and the tanks are supported on legs....

The number, design and size of legs can typically be supplied by the fabricator, but some firms have thier own standards.

Talk with a large tank/pressure vessel fabricator with an ASME Code stamp

Try these people...
