Which term is used to describe small mounds of corrosion formation in pipes?

The term used to describe small mounds of corrosion formation in pipes is tuberculation. This phenomenon occurs when localized corrosion leads to the formation of small, rounded protrusions or mounds on the inner surface of metal pipes, particularly in water systems. These tubercles are often composed of iron oxides and can disrupt the flow of water by narrowing the diameter of the pipe or creating turbulence, potentially leading to further corrosion or failure.

Tuberculation can significantly affect the structural integrity of pipelines, as well as water quality, by trapping sediments and bacteria. Understanding this process is critical for maintenance workers responsible for ensuring the longevity and safety of utility infrastructures.
