Title: Cathodic Protection of the Underground Water Pipelines
Abstract: The cathodic protection was designed through an on-the-spot investigation of soil corrosivity to the water supply steel pipelines in the emergency project of diverting water in the Yingna River to Dalian city. Practice over 30 months indicates that the cathodic protection system keeps stable after the water supply steel pipeline was put under cathodic protection. And the potential is evenly distributed, and the working potential of the anodes has quite a relatively negative value.Thus, the system can supply a high drive potential and the pipeline is in a well-protected condition.The electrochemical corrosion is inhibited,and the design criterion is reached.
