The onlet-oulet cover of a shell and tube heat exchanger was studied by finite element method. The temperature field of the onlet-oulet cover under the steady state condition was analyzed, and the stress field of the onlet-oulet cover under combination action of temperature load and pressure load was calculated. According to ASME Code, stress analysis and safety assessment of the important parts of the onlet-oulet cover were carried out. The results show that the design of onlet-oulet cover is in a safe range, and can meet the requirements of the specification. The article can also provide a reliable basis for engineering design and safety assessment of the onlet-oulet cover.
