埋地燃气管道牺牲阳极阴极保护法的改进

The Improvement of Anode and Cathode Sacrificial Protection of Buried Gas Pipeline

分析我国城镇埋地燃气管道的腐蚀原理,介绍阴极保护在城镇燃气管道防腐中的应用,从测试桩结构的改进、阳极布局原则的调整和测试桩布局原则的调整三个方面阐述了对牺牲阳极阴极保护法的改进,对埋地燃气管道的腐蚀防护有一定的借鉴作用。

This paper introduced the urban buried gas pipeline corrosion theory and anode and cathode sacrificial protection used in the urban gas pipeline antisepsis. The improvements on the structure improvement of test pile, the adjustment of anode and the layout of test piles are mainly discussed in the paper. It＇s hoped that cathode protection can be better used in buried pipeline of the cities and towns. It＇s found that cathode protection has certain value in gas pipeline corrosion protection engineering.
