Detection of the effect of cathodic protection system

After the installation of cathodic protection system, its protection effect should be tested, and its operation and protection effect should be continuously monitored even in normal operation. This is true for both sacrificial anode cathodic protection and external current cathodic protection.

There are two purposes to detect and monitor the protection effect of cathodic protection system

First, in order to detect the corrosion protection status of the protected structure, if the expected protection effect is not achieved, measures should be taken to adjust;

The other is to detect the operation of cathodic protection system. If there is a fault or damage, it needs to be repaired and changed to ensure its normal operation.

We usually use the naked eye or a magnifying glass, It is necessary to measure the corrosion rate of the buried structure by ultrasonic method, and to measure the corrosion rate of the buried structure by visual inspection.

After the cathodic protection system is installed and operated, the protection potential of the structure must be detected in the whole process. The corrosion potential of structures without cathodic protection is an important parameter to characterize the corrosion state of structures in environmental media. The structure potential after cathodic protection is an extremely important parameter to judge the effectiveness and protection degree of cathodic protection system. At the same time, it can also be used to judge the existence and degree of DC stray current interference and AC interference.
