Underground petrol tank : Why is a piece of magnesium metal connected to the underground petrol tanks?
A piece of magnesium metal is connected to underground petrol tanks as a sacrificial anode to provide cathodic protection against corrosion. Petrol tanks are typically made of steel, which is prone to corrosion in the presence of moisture and other corrosive agents.
When a magnesium anode is connected to the steel petrol tank, it forms a small electrical circuit in which the magnesium anode acts as the anode, corroding preferentially to the steel tank, which acts as the cathode. This process helps to slow down or prevent the corrosion of the steel tank, thereby extending its lifespan and reducing the risk of leaks or spills.
Cathodic protection is a commonly used technique for protecting underground petrol tanks and other steel structures from corrosion. By sacrificially corroding the magnesium anode, it provides a long-lasting and cost-effective solution for protecting the petrol tank against corrosion.
It is important to note that the effectiveness of the cathodic protection system depends on a variety of factors, including the quality of the anode, the soil conditions, and the design and installation of the system. Therefore, regular monitoring and maintenance of the cathodic protection system is necessary to ensure it is functioning properly and providing adequate protection against corrosion.
