Eins,

That is I said as well, I said wall stress had to be determined. Then I posted the formula on how wall stress is determined.

Since tanks are not used to hold compressed gas, they do not need to be hydrostatically tested. The DOT only requires cylinders to be hydrostatically tested.

Thanks for the link.
