摘　　要：研究了压水堆核电站中某热交换器换热管与管板的胀接工艺,采用液袋式超高压液压胀管机进行胀管试验,胀管后通过对试验件的外观和尺寸检查、接头的密封性试验以及机械强度试验,从而确定最佳的胀接工艺参数,满足RCC-M规范中对胀管工艺评定的相关要求。The expanding process qualification in nucleal heat-exchanger was studied by using hydraulic liquid bag model expanding machine. After expanding visual inspection, dimension joint leakage test and strength test were performed to get the optimum parameters to ensure in requiements of RCC - M specifiction.
