Flow-accelerated corrosion - Wikipedia

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.

Corrosion Basics: Steam Generation in Power Plants

Apr 01, 2016· Corrosion Basics: Steam Generation in Power Plants The greatest use of high-temperature water and steam is in electrical power generation. Historically, fossil fuels were used almost exclusively to heat water for steam until the introduction of nuclear power steam generators.

The Effects of Erosion-Corrosion on Power Plant Piping

Major failures have occurred in piping due to single-phase or wet-steam erosion-corrosion, resulting in injuries or loss of life as well as extensive plant downtime. Both nuclear and fossil power plants as well as petrochemical plants are susceptible to erosion-corrosion.

Corrosion and Insulation at Power Plants - Insulation Outlook

Jul 01, 2011· Corrosion issues at a power plant can be very costly and, in some cases, life threatening. Not too long ago, three men were killed while working under a steam-generating boiler when a boiler supply tube weld ruptured—due in part to corrosion attack—causing hot steam and ash to fall on them.
