The characteristics of Shi Dongkou east gas steel pipeline buried in soil were discussed and its parameters related to safety were measured, including the state of anticorrosiv e layer, the soil resistivity, the natural potential and the protective potential of gas pipeline. The experimental result s were confirmed by excavating, which are of value to the knowledge of the gas pipeline buried in soil in Shanghai. The experimental data were analyzed which provide the scientific basis for the assurance of the gas pipeline safety and the reparation of anticorrosivelayer.展开更多
