Cathodic protection is a technique used to control the eroding of a metal surface. Scientifically speaking, it holds it by making it the cathode of an electro chemical cell. It connects the body with a metal, which is sacrificial and will act as an anode.
The duplicate or the sacrificial metal then keeps eroding instead of the real protected metal. Cathodic protection massively helps in keeping safe a huge amount of metal structures in different environments. This way, you don't have to worry about the real metal getting eroded or rusted due to environmental conditions.
Here's why you must invest in above-ground storage tanks repair for your home.
Why storage tanks need cathodic protection
A carbon water storage tank is extensively used in the water system. Every water storage structure comes with a concern for corrosion. The material used over time can get eroded and oxidized. Ground storage tanks face several problems like external corrosion because of inferior installation methods and less security.
Cathodic Protection for tanks is the best way to control such failures caused by decay. Previously storage tanks used a sand-based foundation, which resulted in a big loss. For this disadvantage, now cathodic protection is included in the above-ground storage tank.
Everyday items that are saved with cathodic protection are-
● Steel water tank
● Fuel channels
● Steel storage tanks such as home water heaters
● Steel pier piles; ship and boat hulls
● Offshore oil platforms and onshore oil well casings
● Offshore wind farm foundations
● Metal reinforcement bars in concrete buildings.
How are above-ground storage tanks provided cathodic protection?
Above ground storage tanks have inside coating as a primary defense for preventing corrosion at the most internal level. One way to prevent decay is by installing a cathodic protection system inside the storage tank. Cathodic protection supplies electrical current to those areas not isolated from the environment and is coated to prevent the loop of erosion. Water tanks are a crucial investment for municipal water systems. The cathodic application provides sufficient protection to both external and internal corrosion.
Potential measurements are done once the tank is installed and placed at an accurate location. The cathodic protection system will be installed in the interior or exterior and placed above the ground. There are various methods to apply cathodic protection to an already existing tank for this. Take the help of an engineer and ask them which cathodic protection system is suitable.
