| Abstract: | The principle for metal pipeline detection of anticorrosive coating using direct current voltage gradient （DCVG） technology and its application to city gas pipeline are expounded. Four methods to avoid or judge the interference with the detection signal from sacrificial anode are proposed and verified in practice |
| Keywords: | steel gas pipeline direct current voltage gradient （DCVG） sacrificial anode detection of anticorrosive coating integrity assessment |
