Abstract: Long-distance water pipelines are the core components of water resources allocation project. The corrosion behavior of water pipelines is crucial for the reliability of water resources transmission and supply systems, aiming to sort out the relevant research findings on corrosion behavior and its corrosion prevention measures of the existing water pipelines, and provide ideas for corrosion prevention research on long-distance water pipelines. By deeply summarizing the impact of three factors such as chemical environment, fluid characteristics and material properties on the corrosion of water pipelines, the different corrosion mechanisms of electrochemical corrosion, chemical corrosion, and microbial corrosion were analyzed, and the applicability of three commonly used anti-corrosion methods, namely anti-corrosion coating, cathodic protection and pipeline material, was discussed. Finally, the related research on corrosion behavior and corrosion prevention measures of water pipelines were prospected. Existing studies show that the research on factors and behaviors of water pipeline corrosion is mostly focused on a single form of corrosion under strong corrosive media. It is necessary to further carry out the corrosion mechanism research on different corrosion behaviors under multi-influential factors and explore more economical and practical corrosion prevention measures at the same time.

摘要： 长距离输水管道是水资源调配工程中的核心组成部分，输水管道的腐蚀行为对于水资源输送和供应系统的可靠性至关重要，旨在梳理现有输水管道腐蚀行为及其防腐措施研究的相关成果，为长距离输水管道防腐研究提供思路。通过深入总结化学环境、流体特性和材料性能3种因素对于输水管道腐蚀的影响，分析电化学腐蚀、化学腐蚀和微生物腐蚀的不同腐蚀机理，探讨了防腐涂层、阴极保护和管道材料3种常用防腐手段的适用性。最后，对输水管道腐蚀行为及防腐措施相关研究进行了展望。现有研究表明：关于输水管道腐蚀因素及行为的研究多集中于强腐蚀介质下的单一腐蚀形式，有必要进一步开展多影响因素下不同腐蚀行为的腐蚀机理研究，同时探索更加经济实用的防腐措施。
