Sacrificial Magnesium Anodes (for corrosion prevention) and Innovative, fully enclosed, bolt cap
Pioneer water tanks are installed with a sacrificial magnesium anode. Normal corrosion results from a transfer of ‘ions’ and hence electrical current flow between anodic and cathodic zones of a metal surface. These zones of different potential develop primarily due to variations in metallurgy, oxygen and moisture levels. When connected to the structure, the magnesium anodes act to counter this transfer by providing a source of electrical current such that the overall net current flow (hence corrosion) approaches zero. A secondary effect is the transfer of calcium and other alkaline salts through the soil being deposited on, and protecting the metal surface. This film is known as a calcareous deposit and serves to further inhibit corrosion by elevating the pH to a more alkaline condition.
