Flow-induced corrosion (FIC) mechanisms (flow-accelerated corrosion – FAC, cavitation erosion and liquid droplet impingement erosion) are hard to control degradation mechanisms. Their occurrence and severity depends on a series of system-related, material-related and water-chemical conditions.


COMSY-FAC (Condition-oriented Aging and Plant Life Management System) locates pipe system areas which are at risk for damage due to flow-accelerated corrosion.
The heat balance diagram of the power plant is modeled In COMSY-FAC. This permits an analytical calculation of the conditions in the water-steam cycle and a prognosis of the risk of damage.


Your benefits

  • Identifies and localizes systems and sub-systems sensitive to FAC
  • Conservative lifetime evaluation and weak-point analyses of components
  • Inspection program optimized for the needs of your plant
  • Design studies for plant modernization or power uprates regarding the optimization of material selection and geometry
  • Quantification of the iron ingress into the steam generator (SG)
