Sacrificial anodes can be used on the following:
- Storage Tanks
- Power station intake screens
- Great and potable water tanks
- Ships and boat hulls
- Dock Gates
- Jettison and pontoons
- Quay and harbor walls
- Wave and tidal generators
- Wind turbine foundations
- Subsea structures
Generally, the Advantages of using Sacrificial Anode are manifested in cathodic protection. The anodes are linked to the hull of a ship electrically. Furthermore, the metals in the Sacrificial Anode are more reactive than the one used in making the systems and body of the ship. Consequently, they act as the “sacrificial lamb” for the ship’s systems and body in that they corrode in place of the latter, which is, therefore, maintained in its normal un-corroded state. This unique protective function earns the piece of metal its name: Sacrificial Anode.”
Its ability makes it the best material of choice for any metal object submerged in water, especially if the object is susceptible to rust. It can cover the external surface of the object and rust in its place. It offers cathodic protection to these objects to prevent marine corrosion from occurring on them.
The Sacrificial Anode is powered by a regulated dc power supply, which generates the required current essential for polarizing the hull. The current is protective and well distributed by inter anodes of platinum-coated tantalum, which is specially designed for the purpose.
The unique advantages of using Sacrificial Anode are summarized below:
- There is no need for an external electrical power
- It offers very cheap means of protection for the ship’s hull and systems, as well as other submerged metal objects.
- Little maintenance is required, and the anodes are fool-proof
- The anodes are also easy to install
- The ship’s hull and systems can be adequately protected from marine corrosion until the metal is consumed entirely.
- It has a high level of reliability and adequately prevents damage to a ship or any other submerged metal object
- The anode bears no risk of interference into the ship’s system
- Furthermore, it is compatible with other CP systems on subsea equipment
- It equally has automatic control features, which varies and monitors the currents needed for corrosion protection.
Various types of available anodes
- Zinc Elements, Rod and Plate anodes for engine coolers
