Zinc Ribbon Anodes

A zinc ribbon anode provides cathodic protection (CP) for underground coated pipelines. Zinc, being a sacrificing element in zinc ribbon anodes, contributes to a very simple, cost-effective and maintenance-free corrosion control method for buried or immersed metals such as iron, steel, aluminum or copper. Zinc ribbon anodes are an ideal solution only for coated pipelines.

Zinc ribbon anodes are especially useful:

• Where human intervention is limited or for isolated locations (e.g., intrastate or interstate pipelines)
• Where other cathodic protection (CP) systems require monitoring and frequent maintenance
• Where an external power source are not possible (e.g., locations where equipment is battery or solar powered)

Zinc ribbon anodes are used in a variety of applications, including:

• Simple and cost-effective solutions that provide cathodic protection to underground petroleum, water or sewage pipelines
• When the effect of an AC current on pipelines must be minimized
• As sacrificial cathodic protection on the bottom portion of storage tanks built above ground
