摘要
我国西部沙漠、戈壁地区建设了大量的天然气长输管道,由于西部地区尤其是沙漠地区土壤电阻率普遍较高,且地下水位埋藏较深,一般的牺牲阳极或强制电流浅埋辅助阳极不能满足阴极保护的技术要求,因此,深井阳极在该地区的应用日渐深入和广泛。文章介绍了内蒙古鄂尔多斯地区长距离输气管道采用新型深井阳极阴极保护技术的情况。
A great deal of long gas transmission pipelines have been built in the west desert region in accordance with the policy of west exploitation. But the normal sacrificial anodes or shallow buried groundbeds of impressed current cathodic protection do not work very well because the soil resistivity is so high and the groundwater is so deeply. So the deep well anodes are used more and more in the desert region. The application of new type of impressed current deep grotmdbeds to pipelines built in Erdos in Neimeng Province was introduced.
