摘要
结合工程实例,指出通电电位测试法、极化探头断电电位测试法的不足,提出拉铜线结合极化探头法。通过测试得知,拉铜线结合极化探头法能有效测试管道任意位置的阴极保护电位,尤其是测试长距离定向钻穿越段管道的阴极保护效果。
The deficiencies of the energized potential test and the polarized probe off-potential test are pointed out with an engineering example. The method of polarized probe combined with copper wire was proposed. The test results indicate that this method can measure cathodic protection potential of pipeline at any position effectively, especially the cathodic protection effect for a long-distance pipeline by directional drilling.
