Abstract:

With the increasingly widespread application of low-temperature pressure vessels in petrochemical projects, pressure vessel engineers must select low-temperature steel that can ensure both the safety and economic reasonableness of pressure vessels according to the design factors for low-temperature pressure vessels such as design conditions, operating temperature and corrosion performance of media. This paper mainly analyzes and compares the material selection for low-temperature pressure vessels from the aspects of chemical composition and mechanical properties, and presents some application examples in engineering design, so as to help the engineers understand the material selection for low-temperature pressure vessels.
