Soft PVC cemented with epoxy adhesives was used as the inside lining of the metal plate and its anti-corrosion performance was analyzed through the electrochemistry impedance test in this article.

This paper introduce types and mechanism of corrosion of underground metal pipelines and structures and anti-corrosion methods.

Its advantages are: anti-condensation, overheating, rust and corrosion, the protection of all cooling system metal surfaces, including aluminum parts.
