CASE STUDY OF TEMPERATURE ANALYSIS PERFORMED ON A 45inch DIAMETER HEAT EXCHANGER FLANGE

摘要

This paper presents an overview of thermal and mechanical analysis performed on the tubesheet joint of a 45 inch diameter feed/effluent heat exchanger to determine the effects of temperature on the joint operation. Two methods of analysis are used, a new analytical approach and Finite Element Analysis (FEA). The analysis determined a potential problem with the operation of the joint in the intended service and a method of improvement was proposed. Some pitfalls of the methods of analysis, for both the analytic method and FEA, are presented. The comparison between the analytic approach and FEA clearly outlined the advantages of each method in determining the operability of heat exchanger joints.
