Erosion-corrosion of stainless steel pipes under two-phase flow with steam quality 26%

High-speed, two-phase, water vapour flows in the outlet pipes of power reactors. Erosion-corrosion experiments of stainless steel pipes were performed by the use of a component test loop, in which high-temperature, pressurized water vapour is circulated. Small pipe specimens were fixed in the pipes, and erosion-corrosion testing was performed under a two-phase flow of 28.8 t/h with steam quality 26%. Erosion-corrosion losses were very small and almost constant for steam phase velocities of 14-53 m/s
