摘要
双兰线某阀室设置了一处保护干线的外加电流阴极保护站,其阳极地床距西气东输一、二线均不足200m,存在通电电位异常问题和干扰风险。通过现场测试对干扰问题进行判断,提出整改措施及建议。
An impressed current cathodic protection system was built to protect the Shuanglan pipeline in a valve station. Its anode bed is close to the first and second west-east gas pipelines with a distance of less than 200 m, the tested potentials showed the existence of abnormal cathodic protection and interference. Field test of potentials was used to judge the interference. Some solution measures and suggestions of the above issues were proposed.
