erosion-corrosion

A type of corrosion produced when easily removed scales (such as iron carbonate) that were initially protecting the metals in the pipe are eroded and the underlying metals are corroded.

Erosion-corrosion is a common cause of failure in oilfield equipment. The attack is normally localized at changes of pipe sections, bends or elbows where there is high velocity or turbulent flow.
