Bagged Sacrificial Anodes for Bores, Bore heads, Casings,

Tanks, Under Ground Tanks, Pipes, Sheds, or any Metal structures

An Introduction to Sacrificial Anodes

What are Anodes and how do they work?

Simply it is the use of a very pure metal to attract the destructive electrolysis that causes rust, away from the metal surface and onto itself.

Sacrificial anodes have been in common and constant use in a multitude of applications for many years. They protect all ships at sea, underground and above ground pipelines, boilers, water heaters and generally steel structures immersed in water or damp soil conditions where corrosion could be expected to be a problem.

The corrosion (rust) is the result of electrolytic action travelling through moisture or fluid to home in on the metal surface at risk. Depending upon the existing conditions such as amount and quality of the fluid (water?) and the effective presence of any other protective coating on the metal surface, the rate of corrosion can vary substantially.

For this application the anodes are of a particular grade of magnesium which is “electro-negative relative to steel” which means that they will attract the destructive electrolytic action on to themselves. This type of galvanic protection is called sacrificial and the principle of electrolytic corrosion control is called cathodic protection. Because cathodic surfaces cannot rust, the steel surface is protected while an active anode is in place.

GENERAL

Anode Life: The life of the anode will vary through differing factors such as soil type, soil moisture, water quality and the quality of the surface being protected.

 Replacement: It is recommended that your anode be inspected and replaced when more than 50% of its central wire core is exposed through corrosion. Bagged anodes are normally replaced after approx 10 years.

Application: “MetalGuardBagged  anodes are recommended for use with any in ground metal structure, in new and existing tanks and bore applications.

Consumption of  anodes through corrosion means that they are doing their job correctly!

SAFETY

  “MetalGuard bagged anodes conform to Australian Standard AS2239.

This standard advises that the by-products of magnesium anodes commonly used in “potable water applications”  are non-toxic.
