What is Pipeline Corrosion? - Definition from Corrosionpedia

Pipe materials affected by corrosion include metal and non-metal pipes, pipe joints, welds and surface coatings. An example of pipeline corrosion is metal rusting in the presence of moisture and oxygen, which results in the formation of oxide of the metal, such as iron.

Some Failure Analysis Case Histories in Galvanized Steel ...

When wooden hulls were superseded by iron and steel, zinc anodes were still used. In 1836, Sorel in France took out the first of numerous patents for a process of coating steel by dipping it in molten zinc after first cleaning it with 9% sulfuric acid and fluxing it with ammonium chloride. He provided the process with its name "galvanizing".
