Abstract
Taking outbound sub-high pressure pipeline of a gate station as the research object,an impressed current cathodic protection system is installed for bur-ied steel gas pipeline in service.The technology of im-pressed current cathodic protection is introduced,and the design and calculation method of impressed current cathodic protection system using a deep well anode ground bed is given.After the anode installation is complete,the grounding resistance of the measured deep well anode is 0.07 Ω.After the impressed current cathodic protection system is put into operation,the to-tal resistance of the cathodic protection system circuit is calculated to be 6.48 Ω based on the data displayed on the potentiostat.The power-off potential of each test pile is in the range of-1.2 and-0.85V,achieving the protective effect,which proves that this method is effec-tive and relatively accurate,and provides a basis for the design of deep well anodes in the future.关键词
