Problems in cathodic protection
Thread Content
The dry acid cooler under anodic protection experiences significant fluctuations in control and monitoring parameters, ranging between 100 and 300. The acid pipes in the anode protection drying tower experience significant current fluctuations, ranging from 3 to 20A. What could be the cause of this, and what impact does it have on the equipment?
Corrosion may occur on the protection and management surface
It may be due to unstable control of acid concentration, especially when the acid concentration is below 92.5%.
1. Set it to manual mode and check whether the potential shows a large range of variation. 2. The main focus should be on ruling out problems with the acid cooler, the anode protection system, or the processing process itself. 3. For example, cathode leakage, unstable electrode characteristics, interference, poor contact, and faults in the potentiostat can all cause the aforementioned problems.
