| 中文摘要: |
| 针对某型船板式冷却器B10海水管路频繁穿孔漏水问题，本文基于故障树分析理论，以故障海水管路的腐蚀环境、腐蚀形貌和腐蚀机理为层次，将可能导致海水管路穿孔漏水的各种因素作为底事件列出，通过逻辑联系形成上述问题管路的故障树模型。在逐一分析故障树各项底事件的发生原因和典型表现后，将故障原因定位为B10管路与冷却器钛合金板片之间发生异种金属电偶腐蚀，并进行了原理复现，以验证分析的正确性，最终提出包括增加电绝缘组件在内的一系列治理措施，在船上实施后，取得了较好的治理效果。该分析方法可为各类舰船海水管路腐蚀问题的分析定位和治理防护提供借鉴。 |

| There are various causes of corrosion in the seawater pipeline system of a ship. Its analysis and locating is essential for controlling corrosion. Focusing on the frequent perforation leakage of B10 seawater pipeline of a certain plate cooler and based on the fault tree analysis theory, factors that may lead to perforation and leakage of the seawater pipeline were listed as the bottom events, in terms of corrosion environment, corrosion morphology and corrosion mechanism of the seawater pipeline. The fault tree model of the faulty pipeline mentioned above was then built through logical linkage of the events. After analyzing the causes and typical performance of each bottom event of the fault tree one by one, the cause of the fault was located as the occurrence of electro-chemical corrosion between the B10 pipeline and the titanium alloy plate of the cooler. A principle reproduction was carried out to verify the correctness of the analysis. Finally, solutions including the addition of electrical insulation components were proposed, which achieved satisfying results after implementation on the ship. This analysis method can provide reference for analyzing, locating, treating and preventing corrosion of seawater pipelines for all kinds of ships. |
