Evaluation of Stresses in a Cylindrical Pressure Vessel with Varying Internal Pressure, Shell Thickness and Shell Diameter

Abstract

The present work gives information about the stresses in a horizontal cylindrical pressure vessel with different types end closures by varying the internal pressure and thickness and diameter of vessel shell. The pressure vessel is designed for 40 Liter volume and 9 bar pressure. The end closures of pressure vessel is tori spherical dished head. However. Influence of three parameters, that is, thickness of shell, internal pressure, and internal diameter of shell over the longitudinal stresses and circumferential stresses are studied. One parameter varied sat a time and the other two perimeters kept constant. The results of longitudinal stresses and circumferential stresses obtained are presented in this work. A horizontal cylindrical pressure vessel was required for storing 40L gas at a pressure of 9 bar for an industrial application. The pressure vessel diameter is 500mm, length of the vessel is 300mm.
