Abstract: Taking the project of cathodic protection for the buried circulating water pipeline of Caoqiao Power Plant as a case, the principle of cathodic protection is briefly introduced and the design and construction method of sacrificial anode cathodic protection for the internal surface of the buried circulating water pipeline are presented, which include the design and construction approaches on the ventilation system required for the construction of the project. The implementation of the cathodic protection project shows that both the design and construction methods for the cathodic protection and ventilation are reasonable and effective.

Key words: circulating water pipeline, internal surface, cathodic protection, sacrificial anode
