Hello Alberto
That analysis is not in the EN code. I had a chat to development, and they told me that was the reason it is not included in PV Elite. As the jacket is a vapour belt, there is no external pressure exerted on the shell, so that is not a problem. The closure bars at either end of the jacket can be calculation using ASME. This is a simple calculation, easy to do by hand, and the shell of the jacket can be calculated as for any cylinder under pressure using EN. Does that help you?
