| Abstract: | The corrosiveness of the circumstances in which pipeline was working was evaluated by testing and analyzing resistivity, pH and physicochemical properties of the soil. Multi- frequency current method in pipeline was applied to test insulated resistivity and to find the places where electric leakage occured in anti- corrosion layer, and accordingly to confirm the risk point of pipeline operation, to dig and check the status of anti- corrosion layer and corrosion in pipeline by reference of the natural landform. The cathodic protection effect was evaluated by adopting close interval measuring techniques to measure and analyze the cathodic protection status in gas gathering pipeline system. |
