Abstract
Material corrosion tests were done in flowing two-phase fluid of an acidic geothermal well with high velocity in the range of 70 to 100 m/s.The results demonstrated that the effects of the flow turbulence on corrosion increased as the decreased, and as the temperature increased, and that the corrosion was further increased due to turbulence in an expanding flow situation. Duplex stainless steels and higher-alloyed materials gave superior performance to conventional stainless steel alloys.
