| Abstract: | Expansion between tube and tubesheet is a key process during the manufacture of heat ex- changers , and the expansion quality affects the use of heat exchangers. The basic principles of expanding technology and the key points of quality control for expansion during the nuclear island heat exchanger manufacturing were introduced, and three methods （ eddy current profile curve method, inner diameter var- iation measurement, dissection measurement） to evaluate the quality of expansion were studied. |
