| Abstract: | The effect of expanding degree on the connection strength of hydraulically expanded and mechanically expanded tube - to - tubesheet joints of heat exchangers was investigated by experiments based on the specimens with seven triangularly arranged holes perforated in tubesheets. The expanding degree for hydraulically expanded and mechanically expanded tube- to- tubesheet joints was indicated by expanding pressure and tube inner diameter increment rate, respectively. In this study, the number of grooves for grooved - hole joints was taken into account. The reference to select expanding degree and groove for grooved - hole joints was given. |
