Regional Cathodic Protection in Oil & Gas Pipeline Stations

The applications of regional cathodic protection technology to the long-distance transportation oil and gas pipeline stations are introduced.Its protection methods,key technologies,problems and solutions are analyzed.Flexible anode is considered to be a more ideal auxiliary anode.The best programme for regional cathodic protection of the long-distance transportation of oil and gas pipeline stations is adopting impressed current system with a flexible anode as auxiliary anode supplemented by sacrificial anodes.
