DESIGN AND ANALYSIS OF TOP CONICAL END CLOSURE NOZZLE JUNCTION AND PRESSURE VESSEL
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 5, Issue 8
Abstract
In Pressure Vessels, Nozzles are required for inlet and outlet purposes. If these nozzle present on peak of the end closure do not disturb the symmetry of the vessel. However sometimes process requires that nozzles to be placed on the periphery of the pressure vessel. These nozzles disturb the symmetry of the vessel. So that it need to analyzed in FEA to understand effects of nozzle on Stress attributes of the vessel. 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. A visual basic program is included to determine the parameters like internal pressure based on the thickness, actual stress developing in the component, etc. Using the ASME formulae and thin shell theory, the discontinuity forces and moments are determined for vessel and nozzle respectively from which displacements and stresses are found out for individual as well as nozzle junction. The methodology and result obtained from optimization technique and FEA analysis are verified with analytical solution available.
