Double walled pressure vessel

Is it possible to design and analyse double walled pressure vessels using PV Elite ?(Eg of double walled vessel-Liquid oxygen storage vessel operating at cryogenic temperature having one inner vessel made of stainlees steel and one outer vessel made of carbon steel and expanded perlite insulation in the annular space between them)

Hello Ranjit

Yes, it is possible to analyse double wall vessels, but in PVElite, it is not possible to produce one model on the screen to accomplish this. It would be necessary to create two models. one for the inner shell, and one for the outer shell. Ensure that that external pressure for the inner shell includes the jacket pressure and any vacuum existing in the inner shell.
