摘要
Abstract
FEA was used to analyze the force and deformation of coke tower and the pipe in delayed coking unit. Three - dimensional numerical analysis for the pipe flanged joint with belleville spring was carried on to investigate belleville spring's effects on gasket stress under the elevated temperature condition of coking stage. The results of the simulation show that coke tower produces thermal expansion, so induces the bend deformation of pipeline in the coking stage. High temperature's effects on them are more obvious than the pressure's. Proper use of belleville spring is more favourable for maintaining the working stress of gasket of the pipe flanged joint under the condition of elevated temperature.关键词
