| Abstract: | For serious economic loss and life safety issues caused by the event of failure or accident of pressure vessels in industial production, this paper analyzed the significance of the reliability analysis of pressure vessel, took the integrative structure of clyinder of thin film evaporator as an example, adopted the first order second step moment method and the series model for reliability analysis, and obtained the results of reliability for the example under the given conditions, the difference between the external pressure vessel and the inner pressure vessel, thus provides a theoretical basis for the reliability analysis of the external pressure vessel system structure.
