INVESTIGATION ON STRESS CONCENTRATION FACTOR OF PIPING BRANCH JUNCTIONS SUBJECTED TO INTERNAL PRESSURE

Pipe intersections are a regular feature of piping systems and are often the subject of multiple loads, usually acting simultaneously and at irregular intervals. For some time it has been understood that when material is removed from a run pipe in order to accommodate, for example, a branch pipe, the opening in that vessel promotes increased stresses around the edge of the hole. The objective of this project is to investigate the stress concentration factor of piping branch junction resulting from internal pressure using ANSYS. Three different angle of pipe that is 45o, 60 o and 90 o with different ratios of pipe diameter are being studied. The three-dimensional plane stress analysis will be conducted and the von Mises stress is taken into account to determine the stress concentration factor and to analyze the stress distribution at the adjacent pipe hole where the maximum stress are being observed. Reports would be done after each work has been done. In this report, there are some discussions made base on result obtain from the simulation of ANSYS. To be concluded, the effect of different angle and dimension ratio of pipe on the stress concentration factor of the piping branch junction would give a good analysis to enhance the current application of the branch system.
