大连机场某输油管道阴极保护整改及效果评价

Cathodic Protection Rectification and Effect Evaluation of a Certain Oil Pipeline in China Aviation Oil

中航油运营下的航油油库及其输油管道担负着整个机场的储油、输油及卸油的重任,它们的安全稳定运营是整个民航系统的重中之重。本文以大连机场输油管道为例,阐述了采用“外加电流区域保护技术”对大连周水子机场航油油库地下输油管道进行阴极保护改造,以解决机场航油地下输油管道的腐蚀问题。结果表明,外加电流区域保护技术的实施能有效的解决航油地下输油管道的腐蚀穿孔问题,保证航油管道的安全稳定运行。

The aviation fuel depot and its pipeline under the operation of CNAF are responsible for the storage, transfer and unloading of oil in the whole airport. Their safe and stable operation is the top priority in the whole civil aviation system. Taking the oil pipeline of Dalian Airport as an example, this paper expounds the cathodic protection transformation of the underground oil pipeline of Dalian Zhoushuizi Airport by using the impressed current area protection technology, in order to solve the corrosion problem of the underground oil pipeline of Dalian Zhoushuizi Airport. The results show that the application of the impressed current zone protection technology can effectively solve the problem of corrosion and perforation in the underground jet oil pipeline and ensure the safe and stable operation of the jet oil pipeline.
