Abstract

With the acceleration of global industrialization, there is a demand for high-or low-pressure storage of liquids or gases. Because of the complicated operating conditions that will inevitably encounter a possible hazard, pressure vessel design is a critical responsibility. Previous failure studies have revealed that the presence of local loads and discontinuities increases pressure vessel fracture. As a result, a detailed examination of pressure vessel steel from the standpoint of fracture is essential. During service or production, internal, surface, semi-elliptical cracks in pressure tanks and pipes are occasionally observed. A manufacturing fault, such as slag inclusion, cracks in a weldment, or heat impacted zones caused by uneven cooling and the presence of foreign particles, can cause a fracture within a component. Fatigue and fracture as a result Such crack investigations necessitate the estimation of stress intensity factors for a wide range of crack forms and sizes encountered. In this project, we are designing a pressure vessel using ASME section VIII and Division 2 to determine the thickness of the shell, head, nozzle, and leg support. The entire vessel has a uniform thickness. Pro-e 2.0 was used to model the pressure vessel, was used to mesh it. The meshing is done with a 2D Quad element, and the analysis is done with ANSYS Software 11 for two separate instances, working pressure and maximum operating pressure, with a fatigue study, and the result is 106. Finally, the entire model is theoretically validated, with results that are within acceptable limits. Because the pressure is higher than that of the surrounding environment, it is hazardous and, in some cases, fatal. A few pressure vessel instances Pressure vessels hold a considerable amount of energy; the higher the working pressure-and the larger the vessel-the more energy released, resulting in a greater magnitude of damage, disaster, or danger in the case of a rupture.
