Flow-accelerated corrosion in power plants
Flow-accelerated corrosion (FAC), also known as flow-assisted corrosion, is a corrosion mechanism in which a normally protective oxide layer on a metal surface dissolves in a fast flowing water. The underlying metal corrodes to re-create the oxide, and thus the metal loss continues. By definition, the rate of FAC depends on the flow velocity. FAC often affects carbon steel piping … WebApr 25, 1999 · Flow-accelerated corrosion (FAC) is a phenomenon that results in metal loss from piping, vessels and equipment made of carbon steel. It occurs under conditions of flow, geometry and material, which are common in high-energy piping and tubing in nuclear, fossil and industrial power plants. Substantial progress has been made towards …
