What are the two main types of corrosion protection on upgraded steel tanks?

External coating and anode system
Cathodic protection and internal lining
Galvanization and encapsulation
Polymer coating and sacrificial anodes

The correct answer is: Cathodic protection and internal lining

The correct choice highlights the two main types of corrosion protection for upgraded steel tanks: cathodic protection and internal lining. Cathodic protection involves the use of a system that reduces the overall corrosion of a metal surface by making it the cathode of an electrochemical cell. This is typically accomplished by using sacrificial anodes or impressed current systems, which help to prevent corrosion by diverting corrosion effects away from the steel tank. Internal lining provides a barrier between the steel tank material and the contents it holds, effectively preventing corrosive substances from coming into contact with the tank itself and reduces the likelihood of internal corrosion, which can significantly extend the lifespan of the tank and safeguard the integrity of the stored materials. While other options mention techniques related to corrosion protection, like external coatings or galvanization, they do not comprehensively cover the primary methods employed in upgraded steel tanks as effectively as cathodic protection and internal lining do. Thus, the emphasis on these two specific types makes it the most relevant answer for protecting upgraded steel tanks from corrosion.
