| Abstract: | In this paper, the cathodic protection of over-long pipeline is discussed. The electrolyte resistance, surface resistance and metal resistance itself are considered in detail. A series of results of over-long cathodic protection in an infinite region are obtained by BEM. We compare our results with the experimental data and the results obtained by the finite element method in the bounded reg-ion. From the examples, we can see that the cathode can be protected against corrosion with only one anode on the pipeline. |
