Abstract
Fluid machinery and environmental equipment that handle high-speed corrosive fluids are subject to risk of deterioration due to chemical and mechanical actions of such fluids and may eventually undergo operation shutdown, fluid leakage and/or explosion due to the damage to the machine, leading to economic loss and safety and security hazard. Chemical and mechanical actions of the fluid may affect the material respectively (corrosion or erosion) or in combination (erosion-corrosion). This report will summarize the phenomena and mechanisms of corrosion, erosion and erosion-corrosion of the material from the view point of the flow effect of the fluid (liquid, gas and solid) handled, and describe instances of, and measures taken against, the erosion-corrosion and slurry-erosion of pumps and the erosion-corrosion of heat transfer pipes of fluidized bed incinerator.
