The sacrificial anode feet are rusting
Thread Content
I have a question for everyone: in order to reduce the corrosion of equipment caused by chloride ions, sacrificial anodes are used. However, if the foot plates of these sacrificial anodes rust, will that affect their service life? If it has an impact, how can rust on the footplate be avoided? Thank you!
Unless the welding strength is insufficient to support the anode body, the specification requires full welding; however, this generally does not affect the effectiveness of cathodic protection. It is itself cathodically protected by the anode.
As long as the sacrificial anode remains connected to the equipment being protected, it should not affect the function of the sacrificial anode.
The cross-section of the connection parts used in teaching support projects is relatively small, making them prone to rusting and breaking; they can be protected by applying paint on the outside, as long as the anode can provide a conductive connection.
