| Abstract: | Based on plastic-elastic theory, a deep investigation in expanded join t mechanism of tube-tubesheet expanded joints and heat-exchanger(boiler) was mad e . The influencing factors of connection between tube-tubesheet expanded joints w ere analyzed theoretically and testified on experiment. The suggestions to amend current regulations were put forward. The recommended methods of expanded joints connection can be widely applied. Designing conditions of heat-exchanger can be improved. |
