摘　　要：文章对某聚丙烯装置出料系统中反应器到产品室管线进行重点研究。采用不同管线的长度分别在六种温度工况下的疲劳应力分析情况,比较管线的长度对反应器C管口和产品室A管口的受力和力矩的影响,及其对产品室受到正常冲击力时管口受力和力矩差值的影响。优化设计计算结果显示:管道长度为4300 mm可有效的降低额外应力,确保整个管道的安全性。The pipe in the product discharge system of polypropylene unit is the priority research area in the paper.The effect of pipeline＇s length on the stress and moment of reactor＇s pipe orifices C and product vessel＇s pipe orifices A,and the effect of pipeline＇s length on the different stresses and moments of the product vessel were compared.The conclusion of the the optimizing design and calculation： if the length of pipeline is set as 4300 mm,the extra stress can be reduced effectively,ensuring the safety of the entire pipeline.
