What is atmospheric corrosion?

Atmospheric corrosion refers specifically to the gradual degradation or breakdown of metal due to its exposure to moisture, pollutants, and other environmental elements in the atmosphere. This process typically involves electrochemical reactions, where the presence of water and corrosive agents like oxygen and sulfur compounds leads to the formation of rust or other corrosion products on the metal surface.

Understanding this phenomenon is critical for assessing the integrity and safety of gas piping systems. Metals that are not adequately protected or maintained can suffer from pitting, loss of thickness, and eventually, structural failure over time if proactive measures aren't taken to prevent such corrosion. Recognizing atmospheric corrosion helps in implementing adequate protective coatings and regular inspections to extend the lifespan of metal components used in gas piping systems.
