Zinc Ribbon Anode
Definition - What does Zinc Ribbon Anode mean?
A zinc ribbon anode provides cathodic protection for buried coated pipelines. They provide a very simple, cost effective and maintenance free corrosion control method for buried or immersed metals such as iron, steel, aluminum or copper. However, zinc ribbon anodes are an ideal solution only for coated pipelines.
Corrosionpedia explains Zinc Ribbon Anode
Zinc ribbon anodes are especially useful for:
- Unattended applications
- Those where other cathodic protection systems require monitoring and frequent maintenance
- Where an external power source are not possible
Zinc ribbon anodes are used in a variety of applications such as:
- Cathodic protection of buried pipelines
- Alternating current mitigation on pipelines
- Sacrificial cathodic protection of secondary bottoms on above-ground storage tanks
- Alternating current mitigation grounding mats
- And many other corrosion protection applications
Cathodic protection is an electrochemical method of corrosion control in which the oxidation reaction in a galvanic cell is concentrated at the anode and suppresses corrosion of the cathode in the same cell. This is achieved by placing an easily corroded metal (which acts as the anode of the electrochemical cell) in contact with the metal to be protected.
