临邑站存在多条管线,不同管线采用相互独立的阴极保护系统,通过现场试验,考察了不同阴极保护系统的相互影响情况.结果表明:鲁宁线阴极保护系统对临濮线阴极保护系统存在影响,历史资料调研表明这两条管线间存在相互跨接,但跨接位置不明;综合利用现场跨接试验、多频管中电流法(PCM)测试以及阴极保护电位测试等方法确定了跨接线的位置.
There are some pipelines at Linyi oil/gas station,and each of pipelines has own cathodic protection system respectively.The case of mutual influence between cathodic protection systems was investigated through field test.The results indicate that the cathodic protection system of Luning line had some influence on the cathodic protection system of Linpu line.The historical data research shows that these two pipelines were connected by a jumper wire,but the connected location was uncertain.The location of jumper wire was found by means of field bonding test,pipeline current mapper (PCM) test and cathodic protection potential test.
