API 650 Tanks with internal concrete lining
API 650 Tanks with internal concrete lining
(OP)
When it is used an internal concrete lining (for instance 100 mm thickness), is there any reference for carbon steel atmospheric tanks' shell and bottom "local deviations from theoretical shape" or tank shell out of roundness tolerances?
I know that in API 650 there are some tolerances for fabrication (Section 7), but in the case of an internal concrete lining seems that in order to avoid the concrete cracks during the product filling, the tank fabrication restrictions should be different.
Thanks.

Note that you get some flexing at the shell-bottom connection even if the tank is accurately built.
