Pipeline corrosion is the degradation or destruction of a pipeline due to chemical or electrochemical reactions between the pipeline material and its environment.

This corrosion can occur due to a variety of factors, including exposure to corrosive substances in the fluid being transported, exposure to harsh weather conditions or extreme temperatures, or exposure to corrosive soils or groundwater.

There are various forms of corrosion that can occur in pipelines, including uniform corrosion, pitting corrosion, and corrosion under insulation. Each type of corrosion can cause different types of damage to the pipeline, and some forms of corrosion can progress more quickly than others.

Corrosion can have serious consequences for pipelines, including reducing the strength and stability of the pipeline, creating leaks or other safety hazards, and increasing the risk of environmental damage or spills. For these reasons, it is important to properly design, construct, and maintain pipelines to reduce the risk of corrosion, and to regularly inspect and monitor pipelines for signs of corrosion and other issues.
