Cathodic Protection Design for Large Oil Depots Ever Built

The cathodic protection current in station area drained seriously, the potential distribution was uneven, and there were problems such as interference and shielding. Aiming at the cathodic protection design of a large-scale built oil depot, the application of feeding test in determining the current density of large-scale oil depots was emphasized from the aspects of current density determination, anode bed selection and selection of key equipment. The use of a reasonably distributed shallow buried anode bed can solve the interference and shielding problems. The synchronous on-off of the potentiostat and the application of intelligent potential acquisition system can greatly facilitate the management and maintenance of the regional cathodic protection system.
