Abstract

The tube’s expansion effectiveness in steam generator （SG） tube sheet was analyzed with 3-D nonlinear finite element in this paper. Tube expansion influences of actual size deviation and material characteristics were also researched. Through analysis, contact pressures of several typical tube gaps and tube stiffness were calculated and compared with the results of non out-of-tolerance holes. In the last, reasonable suggestions were provided for the selection of proper expansion pressure.
