摘　　要：为提升一体机膨胀端出口管道的安全性,采用管道应力软件CAESARⅡ对其进行模型构建和数据分析。在正常操作工况下,调整一体机膨胀端出口管道的布置形式,对比自然补偿加Π型弯和加膨胀节2种形式下的设备管嘴受力。研究表明:通过增加Π弯改变管路的走向或增加膨胀节等方式对一体机膨胀端出口管道进行优化调整,可改善管道的柔性,减小一体机膨胀端管口载荷,为一体机膨胀端出口管道的合理布置提供参考。In order to improve the safety of expansion end of integrated machine,pipeline stress software CAESAR II is used to establish the model and analyze the data.Under the normal operating condition,by adjusting the layout of the outlet pipe of the expansion end of the integrated machine and comparing the force of the nozzle under two forms of adding Π bends and expansion joints,it can be concluded that adding Π bends to change pipe direction or adding expansion joints can improve the flexibility of the pipe and reduce the nozzle load of the integrated machine,which provides a reference for rational pipe layout of the integrated machine's expansion end.
