The oil and gas industry relies on the strength of steel and other metals to build pipelines, storage tanks, and other infrastructure that stand up to the rigors of industry activity. However, metal has one major weakness: when it comes into contact with water or soil, it can corrode. It is obvious, corrosion in a pipeline or storage tank is not good.
Cathodic protection (CP) is an electrical method of preventing corrosion on metallic structures that are in electrolytes such as soil or water. It has had widespread application on underground pipelines, and ever increasing use as the most effective corrosion control method for numerous other underground and underwater structures in oil and gas industries. It is a scientific method that combats ...
