Pressure vessels are leak proof containers. These are having wide range of applications in several fabrication industries like steel plants in addition to the main equipment like blast furnace, Nozzles or openings are necessary in the pressure vessels to satisfy certain requirements such as inlet or outlet connections, manholes, vents and drains etc. To incorporate a nozzle on the vessel wall it is supposed to remove some amount of material from the vessel. Then the stress distribution is not uniform. Distribution of stress in the juncture area and the rest will differ as nozzles cause a geometric discontinuity of the vessel wall. So a stress concentration is created around the opening. The junction may fail due to these high stresses. In the present work, the importance of the effect of the discontinuity is mentioned, codes related to design of vessels and its components is discussed; nozzle and vessel parameters are calculated using ASME code formulae. PV Elite is used to determine the design of pressure vessel like the thickness of shell and nozzle data. Different nozzle location with and without reinforcement of nozzle for offset of 0 ,8 16, 24 and 32 inch from vertical centre line at central cross section with different inclination angles like 0Ëš , 15Ëš, 30Ëš and 45Ëš are modeled with Creo Parametric 2.0. ANSYS workbench is used to analyze the model made in Creo Parametric 2.0 by importing it in the workbench environment, generating proper meshing, and applying boundary condition. Von-mises stress and deformation are plotted for all options under study. At initial stage all options are evaluated without reinforcement and then for properly calculated nozzle reinforcement. Summary of all Von-Mises plot are presented in tabulated as well as graphical form. Conclusions are made by discussing from available results. Future scope of work is mentioned clearly from current work for further study.
