cup tank (tank in tank) design code
cup tank (tank in tank) design code
(OP)
I have to design a cup tank (a tank within a tank, the inner is the storage container, the outer is to capture the medium in case of leakage of the inner tank). In design codes for cylindrical storage tanks like API650 and EN 14015 a double-bottom is adressed briefly. However a cup tank is nowhere mentioned.
Before I start making up all kinds of design rules myself I want to check if there are design codes for such kind of tanks. Remember that the outer tank is just a leakage container and the inner is the actual non-pressurized (-5/+10 mbar) storage tank. If any of you can help me it would be highly appreciated. Also design considerations are welcome.
With regards, Corné

Good luck,

I had a tank within a tank on one project - there was a separate liquid stream to the outer section, but even though there were small penetrations between the two areas the tank supplier designed the inner wall for external loading (to ASME VIII) to cover the scenario of outer section full, inner tank empty. Made for quite a thick inner wall, but thankfully not the situation you have.

Both codes deal with primary and secondary containment tanks, UL-58 is for underground tanks, and UL-142 is for aboveground tanks.
