摘　　要：某石化公司原油蒸馏装置减顶液相出口管线发生局部穿孔泄漏现象,经检测分析,其腐蚀原因为H_(2)S-H_(2)O环境腐蚀和液体冲刷腐蚀协同作用的流动加速腐蚀。为保证该装置长周期安全稳定运行,提出相应的整改措施与建议。Local perforation and leakage occurred in the liquid exit pipeline of a crude oil distillation unit in a petrochemical company. Through detection and analysis,the corrosion cause was flow acceleration corrosion of hS-H_(2)O environment corrosion and liquid scour corrosion. In order to ensure the long period safe and stable operation of the device,the corresponding rectification measures and suggestions are put forward.
