Design and Analysis of Nozzle Junction

In various tanks, pressure vessels as well as heat exchanger, nozzle is very important& serves as inlet& outlet for process fluid& cooling fluid. Number of nozzle could be one or more depending upon requirement but it tends to lower strength of parent component, which may lead to failure of vessel. In this paper, nozzle is used for inlet& outlet of propane gas as well as cooling water. In order to improve strength at nozzle shell junction, reinforcement pad is used sometimes to prevent failure. So, here nozzle to shell junction is analyzed by considering various areas which affect strength of junction (either improve or degrade strength)& it is predicted that pad is required or not& if pad is required then its dimensions like thickness& diameter is calculated based on ASME Codes. In addition, finite element analysis of junction is done to check stress induced at the junction.
