What is the impact erosion?
The impact erosion is the loss of material from a surface
subjected to the impingements of solid particles (even very
small) dragged by a fluid.
Why it is a relevant problem in control valves?
Eroson may cause:
Change of the valve’s performace
Valve’s life reduction
Management issues
Service downtime
Main engineering concerns:
• Identification of the erosion hotspots locations
• Erosion rate estimation
