| 摘 要： | 某石化公司柴油加氢装置循环氢水冷器管束多次发生腐蚀泄漏。通过对腐蚀失效管束的腐蚀形貌、材质、垢物成分等结果进行综合分析显示，造成水冷器管束严重腐蚀的主要原因为Cl-局部富集所造成的点蚀引起的，介质的冲刷作用加剧了腐蚀，本文对此提出了腐蚀控制的建议措施。

| Abstract: | Corrosion failure analysis of water cooler tube bundle of a hydrotreater was performed with physical and chemical analysis. The results showed that the leakage of the tube bundle was caused by pitting corrosion, where local enrichment of chloride ions emerged, while the erosion of the medium aggravates the corrosion. At the last, several corrosion control measures are proposed in this paper. |
