Ship Sacrificial Anode


Ship Sacrificial Anode

Sacrificial Anodes are used to protect the hulls of ships, water heaters, pipelines, distribution systems, above-ground tanks, underground tanks, and refineries. The anodes in sacrificial anode cathodic protection systems must be periodically inspected and replaced when consumed.


The special anti-corrosion material ZAC and AZI sacrificial anodes, compound by main elements, is a special product which can prevent the corrosion of steel in seawater and underground. The sacrificial anode is mainly used for the steel body surface of ships, marine engineering and harbor facilities in seawater medium.


Main Materials of Sacrificial Anode

Magnesium, Aluminum and Zinc Alloy
