摘　　要：根据强制电流阴极保护系统的原理,把区域内的几条集输管道作为一个阴极保护整体,管线间采用均压线连接来实施阴极保护,并获得成功。对于业主方而然,这种方法延长了管线的使用寿命,减少了因腐蚀穿孔检修次数;对于EPC承包方而然,以往阴极保护系统都是一条管线使用一套系统,此次单套阴极保护系统,保护了多条管线,为项目节省了成本;具有广阔的应用前景。according to the principle of impressed-current cathodic protection system, several trunklines which are bonded by equal potential wires are integrated into a cathodic system and protection potential along the pipeline is stable and qualified. This approach can prolong the service time of pipeline and reduce the times of repair due to the perforation for the OWNER. This approach also save project cost for EPC contractors since a set of system provide service to several pipelines compared to one pipeline before. Therefore this approach should be widely recommended to other projects.
