CorrosionWikipedia
Corrosion is a natural process that converts a refined metal into a more chemically stable form such as oxide hydroxide or sulfide.It is the gradual destruction of materials (usually a metal) by chemical and/or electrochemical reaction with their environment. Corrosion engineering is the field dedicated to controlling and preventing corrosion.

How To Protect Pipelines From Corrosion
Active corrosion protection involves a set of methods to neutralize the corrosion -causing a reaction in the structure. The technique has an active role in inhibiting the corrosion on the surface of the metal. For example a special chemical compound can be added to fluids passing through the pipelines that make it inert to the corrosion reactions.
