Flow-accelerated corrosion in power plants
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 … Webprotection against corrosion, due to the ingress of corrosive salts, or to flow-accelerated corrosion (FAC), which tends to occur over the temperature range 110–200 °C. FAC is particularly prevalent in the low pressure stages of HRSGs and in carbon steel feedwater heater components of conventional plants, which operate in this temperature range.
