- 摘要:
- 介绍了中国民航津京长185 km输油管道阴极保护系统的检测情况, 检测结果表明, 63个测点的数据绝大多数符合要求, 但塘沽东盐桥至海防路长约4 km管道的阴极保护电位不合格, 为此对牺牲阳极的布设和安装进行了改进, 使该段管道的保护电位也达到了规范要求。
The inspection for cathodic protection system of China Civil Aviation Tianjin-Beijing Oil Pipeline with the length of 185 km was carried out.The results showed that the most of 63 inspection points met cathodic protection requirements, but the cathodic protection potential of the pipeline section from Dongyan Bridge to Haifang Road in Tanggu District with the length of 4 km was not qualified.Therefore improvements were made for sacrificial anode arrangement and installation, then the protection potential of that pipeline section also reached the standard requirement.2012,04(04): 56-59 收稿日期：2011-9-3分类号：TE988.2作者简介：蔡亮(1973－),男,天津人,高级工程师,1996年毕业于解放军后勤工程学院油气储运专业,现从事长输管道的安全技术管理工作.
