Hello dear experts.

I would like if there is some rule or statement in API 650 or 620 or empiric rule that mention the maximun or minimun H / D ratio for AST tanks, regard less the acorage requirement or minimum shell thikness, the main worry is how slender could be a tank regarding the sismic issues.

I am designing a tank with the following dimensions:

diameter: 3.7 m
Height: 9.8 m

I read API 650 app. A table A-1a typical sizes for small tanks, and I found the folowing:

for a 3 m diameter tanks there is an avaible height of 10.8 m.

That means my tank is within the size average, but I woul be more clear about this relation H/D, I wold like read more about this.

Like always it would be hightly apreciate your help, ThANKS in advance.
