对中石化洛阳分公司水冷器换热管的宏观形貌、腐蚀产物、腐蚀特征进行分析,结果表明腐蚀失效的原因主要是水冷器水侧换热管由点蚀、垢下腐蚀和细菌腐蚀协同腐蚀作用的结果.同时提出了从控制腐蚀环境、采用涂层技术、工艺等方面的防护措施. The macro morphology, corrosion products and corrosion characteristics of water cooler tubes in Luoyang Branch of SINOPEC were analyzed. The results show that the main cause of corrosion failure is the co-corrosion of water-side heat exchange tubes from pitting corrosion, scale corrosion and bacterial corrosion The result of the action.At the same time proposed from the control of the corrosion environment, the use of coating technology, technology and other aspects of protective measures.
