I recently UT inspected a 10 year old UL-142 Horizontal tank, diesel service, now Im looking for a way to calculate a minimum thickness, after some research I came up with a minimum thickness to be equal to the minimum thickness for overstand only the weight of the tank itself, because the diesel only means a 2.4 psi of pressure.

Anyone Have any idea of how to calculate the minium thickness of ahorizontal tank?

Any suggestion will be welcome, and thanks in advantage.
