Galvanic Zinc Anode  Marine Cathodic Protection


Xi'an Taijin's  sacrificial Zinc Anodes are applied in Low Resistivity Soils below 1000Ω-cm and in Sea Water or produced Brines.. Zinc Anodes are widely used in bulkheads, piers and pilings, heat exchanger and condenser, pipelines, vessels and tankers. etc.

The performance of Zinc Anodes is affected by the chemical composition of the alloy, we have different alloy series to meet customer's request. Special shape, size and chemical composition anodes can be manufactured according your request.


A galvanic anode is the main component of a galvanic cathodic protection (CP) system used to protect buried or submerged metal structures from corrosion.

They are made from a metal alloy with a more "active" voltage (more negative reduction potential / more positive electrochemical potential) than the metal of the structure. The difference in potential between the two metals means that the galvanic anode corrodes, so that the anode material is consumed in preference to the structure.

The loss (or sacrifice) of the anode material gives rise to the alternative name of sacrificial anode.

Cost effectiveness

As the anode materials used are generally more costly than iron, using this method to protect ferrous metal structures may not appear to be particularly cost effective. However, consideration should also be given to the costs incurred by removing a ship from the water, for example, to repair a corroded hull or to replace a steel pipeline or tank because their structural integrity has been compromised by corrosion.

However, there is a limit to the cost effectiveness of a galvanic system. On larger structures, or long pipelines, so many anodes may be needed that it would be more cost-effective to install impressed current cathodic protection.
