摘　　要：对某同心异径管泄漏事故进行原因分析,通过宏观检验、壁厚测定、腐蚀产物微观形貌及能谱分析、腐蚀产物物相定性分析、硬度检测、金相分析和化学分析,得出该同心异径管的穿孔泄漏的主要原因是空泡腐蚀与冲刷腐蚀联合作用的结果。The accident cause of a concentric reducer leakage was analyzed.Through macro inspection,wall thickness measurement,corrosion product micro morphology and energy spectrum analysis,corrosion product phase qualitative analysis,hardness detection,metallographic analysis and chemical analysis,it was analyzed that the main cause of the concentric reducer perforation leakage was the result of the combined action of cavitation corrosion and scouring corrosion.
