摘　　要：针对锅炉蒸汽管系存在二次应力较大的问题,运用国内市场主流的管系应力分析软件,搭建管系模型,合理布置管系的各支吊节点,计算相应的各工况,检查各工况计算数据,找出管系中存在的不合理项并改进,化解二次应力对管系造成的破坏,以实现管系安全稳定运行。In view of the large secondary stress in the boiler steam piping system, the mainstream piping stress analysis software in domestic market was selected to build a piping system model, rationally arrange the supporting and hanging nodes of the piping system, and calculate the corresponding working conditions. Check the calculation data of each working condition, find out the unreasonable items in the piping system and improve them, and resolve the damage caused by the secondary stress to the piping system, so as to realize the safe and stable operation of the piping system.
