It is found that there is no much difference between the pullout load obtained by mathematical calculation and that of experimental results. It is finally observed that controlling parameters in tube to tube sheet expansion joint are loading pressure,.

Both pull-out and push-out tests were carried out for each joint. Results show that the tube expanding percentage almost increases linearly with increasing the expansion pressures. Pull-out force is less than the push-out force and both of them increase with increasing expansion pressures. However unlimited increase of ...[PDF]Appropriate Correlations for Assessing Expanded Tube-to-Tubesheet ...
