摘要：

A comprehensive study of local pressure stresses at the juncture of a pipe-nozzle is presented. Currently, neither experimental nor analytical data exists that is sufficient for pressure vessel designers to analyze the local pressure stresses at the juncture of a pipe-nozzle. In order to provide a comprehensive database to calculate these pressure stresses, this paper, through a finite element technique, provides a series of local pressure stress factor plots as a function of pipe-nozzle geometrical parameter beta (nozzle mean radius/pipe mean radius) with a range from 0.1 to 1.0 and gamma (pipe mean radius/pipe thickness) with a range from 10 to 300. These local pressure stress components supplement the stress calculations presented by the Welding Research Council Bulletin 107 for other external loadings.
