ASME UHX Fixed Tubesheet and Expansion Joint Analysis
February 20, 2020Fixed tubesheet heat exchangers are often designed with expansion joints to handle the differential thermal growth between the tubes and the shell. Learn how to use Exchanger Optimizer 4.1.6 to specify operating metal temperatures and evaluate the cost impact of adding a flanged and flued or bellows expansion joint modify designs...
TechTip: How Xist Estimates External Pressure Requirements for Pipes and Tubes
January 16, 2017This webinar will investigate how Xist uses ASME code design methods to determine the external pressure requirements for cylinders. Using three cases, we will discuss how to determine thickness for specified temperature and pressure how to determine the maximum external pressure for a specified thickness external pressure limitations as compared to...
Q14-4 Improved Heat Transfer Coefficients for Calculating Tubesheet Temperature
January 16, 2017ASME Code 2007 Section VIII - Division 1 UHX requires an average tubesheet metal temperature for calculating the allowable thermal stresses between the shell and header flanges of a shell-and-tube heat exchanger. The Xist® tubesheet temperature calculations do not take into account the contribution of the heat transfer coefficients on both...
