Design and Analysis of an Unfired Pressure Vessel for Conducting Pressure Test

Abstract： A pressure vessel is defined as a container with a pressure differential between inner and outer surface. The inside pressure is usually higher than the outside, except for some isolated situations. Pressure vessels often have a combination of high pressures together with high temperatures both internally and externally. Any leak under operating pressures may lead to failure of the vessel which causes extensive physical injury and property damage. Because of such hazards it is imperative that the design be such that no leakage can occur. In addition these vessels have to be designed carefully to cope with the operating temperature and pressure. This project set out to design and analyzes a custom made pressure vessel for the required application. Explore applicable methods using finite element analysis in pressure vessel analysis. Having tested three ax symmetric models, the preliminary conclusion is that finite element analysis is an extremely powerful tool when employed correctly. Problems such as local stress risers, unrealistic displacements and understanding how to use such data become extremely important in this kind of analysis. The difficulty in analysis of stress and strain in structural engineering depends on the structure involved. As the structure grows in complexity, so does the analysis. However, these Calculations often provide solutions only for the maximum stress and strain at certain points in the structure. This highlights the key to proper use of finite element analysis. Process starts with performing basic calculations of pressure vessel by using ASME Pressure Vessel code and BIS Unfired pressure vessel code. Once we obtain results from basic calculation we develop software for iteration of vessel parameters. This gives a fine refinement and accurate parameters that require to design a pressure vessel. Later these parameters are developed to 3D modeling in Solid Works 2013, followed by analysis of stress and deflection by ANSYS WORKBENCH 13.0. The dissertation deals with design and analysis of Pressure Vessel with Integral Type Flange.
