Abstract

The paper presents the results of a parametric study, using finite element analysis, of the behaviour of full face metal-to-metal taper-hub flanges. The important stress values in the flange have been obtained for a range of flange thickness, taper-hub thickness and length, when the shell/flange component is subject to internal pressure. The influence of the pre-stress in the bolts is examined. The results obtained have been compared with the predictions from the appropriate sections of the ASME, BS and the new European Unfired Pressure Vessel Standard (Draft BS: prEN 13445).
