摘要
首先分析了现有城镇燃气管网遭受腐蚀发生泄漏的主要原因,提出了在涂敷绝缘层基础上采取阴极保护的必要性;然后介绍了阴极保护的方法、分类及特点;最后从设计、施工和使用等环节重点叙述了牺牲阳极法在城镇燃气管网保护中的应用。
The principal causes to induce the leakage occurred in town gas pipeline net were analyzed, and the necessity of cathode protection based on coating insulation was stated. Then, the methods, classification and features of cathode protection were introduced. With respects to design, construction and usage, the application of electrode abandonment method in town gas pipeline net was finally described.
