Stress Analysis of Pressure Vessel with Different Type of End Connections by FEA

Digvijay Kolekar, Jewargi S.S

This paper deals with the Finite element analysis of Pressure vessels with different type of heads keeping the same cylindrical volume and thickness. The desired pressure vessel is designed as per ASME standard section VIII, division I for 8 bar pressure and 24 lit volume. Thus some end connections are tested under FEA for the cause of finding stress concentration zone in each type of pressure vessel head under the same volume and sane pressure. This paper describes, the hemispherical head and elliptical head pressure vessel has low stresses distributed as compare to other heads, so for most applications elliptical heads selected. It shows basic structure and the finite element modelling for analysing the pressure vessels with different type of heads under high stress zones.In this paper we are working on approximate stresses that exist in cylindrical pressure vessels supported on two saddles support are calculated under the different type of end connections by using Finite Element tool. Static structural analysis is done in order to calculate stresses in vessel
