Pressure vessel is highly used in the industry for the storage of the most diverse types of fluids under various operating conditions. However, despite of the versatility of this equipment, the design of a pressure vessel requires serious care and compliance with a several norms and standards to ensure its safety and suitable performance. The industrial and technological need requires the construction of increasingly resistant and economical pressure vessels, which are suitable for services under extreme operating conditions, such as for use in nuclear reactors. This work promotes a case study around two types of pressure vessels used for services in extreme conditions: thick-walled vessels and multilayer vessels. The case study deals with the calculation of the minimum allowable thicknesses for the cylinders of both equipment according to the premises and equations suggested by the ASME Code, Section VIII, Divisions I and II, besides promoting the calculation of the maximum tensions acting in each vessel through equations obtained from the literature. Finally, at the end of the paper, the results obtained through the formulas of the Code and ones obtained from the equations of the literature are compared and it is possible to verify that the values obtained are consistent with those found in other works of the same type, in addition to meeting the requirements of the standard referenced
