Abstract

Abstract

Using the finite element method to shell-and-tube multiple fixed-tube plate heat exchanger in three kinds of cases,the pull-out force for a heat exchanger and tube-sheets under the different temperature distribution are calculated.The results show that the pull-out force have a bigger difference in the different locations of a heat exchanger tube for multiple exchangers.According to the allowable value of ASME,the pull-out force of all heat exchanger tubes and tube-sheet joint for case 3 can meet the requirements,but the pull-out force of the joints with 56 heat exchanger tubes and tube-sheets for case 1 and with 22 heat ex-changer tubes and tube-sheets for case 2 are over the allowable values.Therefore,under the co-action of vi-bration,corrosion and so on caused by the flow of the medium,it is easy for these joints to rupture and leak.
