Abstract

Abstract

The local wall thinning of steam generator tubes due to corrosion and mechanical wear is the main reason decreasing the bearing capacity and the following rupture of SG tubes.Based on the theory of limit load,the numerical simulation method is used in this paper to estimate the bursting pressure of steam generator tubes.The effect of the volume defect dimensions in all directions on the burst pressure of the pipe is studied.
