摘　　要：核电厂消防水生产系统每台消防水泵均在出口位置设置了1个节流孔板,用来控制流量的最小流量旁通管路,管壁腐蚀穿孔多次出现在这条最小流量旁通管道上。通过分析腐蚀形貌,开展流体力学计算,分析了管道腐蚀泄漏原因,改进了原设计方案。Each fire pump in the fire water production system of nuclear power plant has a throttle orifice plate at the exit to control the minimum flow bypass pipeline.Corrosion perforation on the wall of the pipeline occurs many times in the minimum flow bypass pipeline.Through the analysis of corrosion morphology and hydrodynamic calculation,the causes of pipeline corrosion leakage are analyzed,and the original design scheme is improved.
