Abstract: An approximate analysis of thermal stresses developed in heat exchanger tubing between closely spaced double tubesheets is presented. Tube loading is caused by in-plane differential thermal movement of the adjacent tubesheets. To obtain solutions valid for arbitrary spacing between the tubesheets, the effect of shear deformation is included. The effect of edge restraint such as peripheral flange bolting is also included. Typical results are presented to illustrate the interaction of bending and shear in the tubes.
