| Abstract: | The mechanisms and work procedures of leak detection technology for buried pipelines are introduced.The current gradient method and the correlation method are integrated.Based on the external protection coating test and examinations of damaged parts with associated instruments,the detection efficiency of the leaking points was greatly improved.Case studies of leak detection are presented, which show that this technique is high in accuracy,rapid in implementation and low in operating cost.The application can greatly improve the effciency of pipeline maintenance. |
