Abstract- Pressure vessels are important equipment used for storing and handling fluids underpressure in industries such as oil and gas, chemical processing, and LPG storage. Because these vesselsoften contain hazardous materials, their design must ensure safe and reliable operation under differentworking conditions. In the present study, a vertical pressure vessel was designed based on theguidelines of ASME Boiler and Pressure Vessel Code Section VIII. A 3D model of the vessel was preparedand analyzed using ANSYS Workbench and SolidWorks Simulation software. Finite element analysis wascarried out to examine stress distribution, deformation, and thermal effects produced during operation.The material properties used in the analysis include yield strength of 232 MPa and a Poisson’s ratios of0.3. These properties are applied during the simulation to determine stress distribution, deformation,and structural safety of the pressure vessel. The results indicated that the nozzle-to-shell junction andmanway regions experienced higher stress concentration compared to other parts of the vessel. Toimprove the structural performance, a reinforcement pad was introduced around the nozzle area, whichhelped in reducing localized stresses and improving load transfer. The FEA results were then comparedwith analytical calculations, and both showed good agreement. The study confirms that the use of ASMEdesign standards together with finite element analysis provides an effective approach for developingsafe, durable, and cost-efficient pressure vessel designs.
