Cylinder-cylinder intersection problems are commonly encountered as nozzles in pressure vessels or branches in piping. This paper reports initial results of a finite element analysis on the maximum stresses in the intersecting shell/nozzle loaded by internal pressure. The results presented in this paper are based on un-reinforced cylinder intersections with the nozzle flush normal to the vessel. Results show that the maximum bending stress is significantly bigger than the maximum membrane stress. The effect of the maximum bending stress (at the intersection) is diminished at a distance of approximately 2.35 RT along the shell and 2.5 rt along the nozzle. This result confirms that the length of thickness reinforcement suggested by the PD5500 Pressure Vessel Code is adequate for the nozzle but slightly conservative for the shell.
