API650 tank with bottom cone - NDE
API650 tank with bottom cone - NDE
(OP)
Hello All
I am preparing non destructive examination scope for tank designed acc to API 650 with bottom cone. I can't find NDE requiremnents for bottom cone in API 650 and ASME V. Maybe I didn't see it. Do you know where it could be found ?
Thanks in advance

The fact its a cone floor (I assume) doesn't make any difference - it's still a tank bottom.
Is that what you meant?

Thanks all for help

This is not an API650 tank, that's why there's nothing in it for a cone floor like that as JStephen says So find out first what code, if any, this is designed to.
If in doubt then do whatever you're doing for the shell.
Is this tank freestanding or resting on the ground?

This tank will stand on foundation slab, above ground

so you have part of your tank designed to a code which specifically applies "only to tanks whose entire bottom is uniformly supported..." and basically atmospheric pressure and the bottom section to a pressure vessel code designed for pressures > 15psi.
Glad I'm not signing this off....

Design the whole thing to some sort of generic structural code, as per the original design - EN 1993-4-1. To try and replace this with parts of something else just so that you try and claim it now complies with American codes is not correct (IMHO). Ifthere isn't an American code that covers it then find another one which does - in this case EN 1993-4-1.
The code noted above is specifically to provide design guidance for the structural design of steel silos. Hence you're not "on your own" in this circumstance.
