Abstract

The greenhouse effect is having increasingly impact on global climate; corrosion resistance of pipeline steel for supercritical CO2 transportation has become an important research topic [1]. In this paper, four common pipeline steels (X65, X70, X80, X90) are electrochemically tested in a carbon dioxide saturated aqueous solution in the gas phase using a Princeton 2273 electrochemical workstation. The results show that in the range of 20–50 °C, the corrosion rates of X65 and X80 pipeline steel reach the maximum at 40 °C and X70 and X90 pipeline steel reach the maximum at 50 °C. The research of this paper provides technical support for the safe operation of CO2 pipeline。
