Abstract
A shell and tube type heater exchanger is disclosed for withstanding cyclic changes in temperatures of fluid without suffering failure by removing metal from the outer periphery of a tube sheet. The central portion of the tube sheet is a smooth arching contour mating with portions of the adjoining shell proximate to the tube sheet periphery without abrupt changes of section so that the surfaces blend with one another.
