According to service condition and theory of correlation

this paper analyzes the influence of temperature on the vessels design in choosing of the vessels material

determining of admissible stress and design methods.Different materials have different range of design temperature.Designing high temperature vessels

graphitization of carbide and carbon content is separately considered for carbon steel and carbon manganese steel.Low temperature materials must have enough ductility.Determining the admissible stress of high temperature vessels

high temperature lasting and creep strength must be considered.For vessels that thermal stress must be considered

must be designed according to stress analysis method.For low temperature vessels

giving out decision methods of low stress or fall stress and their design methods.
