Text explaining flow-accelerated corrosion (FAC), its causes, mechanisms, and effects. It discusses the dissolution of iron oxide layers on steel due to water or steam flow, leading to increased corrosion and metal loss. Factors like reduced pH and turbulence also affect FAC. Key terms: ductile overload, two-phase flow, turbulence, reduced oxygen levels.
Image showing a text titled 'Oxide Formation-Breakdown' with chemical reactions for metal oxidation, magnetite and hematite formation, and related processes in HRSG circuits. The text discusses alkaline water effects, reducing conditions, and protective layer formation in power plant systems.
