Strictly speaking, you need to go to the manufacturer/designer and find out what minimum wall thickness is called out on the drawing.

Only if that fails, buy a copy of BS EN 286-1:1998+A2:2005, from which you will be able to calculate a minimum wall thickness that should match the one the designers came up with (this vessel is over the 3000 bar-litre threshold, so they will have been obliged to use the formula in the standard).
