Static Analysis of Pressure Vessel for Verifing the Requirement of Expansion Joint

Abstract

Expansion joint have a function to absorb regular or irregular expansion and con-traction in piping system, it is widely used as the element of expansion joint in various piping system, aerospace, micro electromechanical and industrial system. Most industrial piping system often suffer excessive deformation, displacement, heat expansion, vibration, and other causes are responsible for the failure. The main issue is to verify that there are various deformation stresses which is build due to various factor in pressure vessel such as thermal stress, internal pressure etc. and check whether there is requirement of expansion joint to reduce those stresses.
