Abstract: The calculation of baffles inside pressur evessels has long been neglected. Many designers determine the thickness of baffle plates and the parameters of baffle stiffeners only based on their personal experience. Sometimes, the baffles are damaged because of insufficient thickness of plates or low parameters of the stiffeners. This paper introduces the calculatio nmethod of baffles which are welded directly tothe shell of pressure vessels and presents the detailed calculation process through examples so as to help readers make better use of this calculation method in the baffle design process.

Key words: pressure vessel, baffle, calculation model
