The effects of environmental factors such as temperature, oxygen content, solution chemistry and flow rate on CO2 corrosion of linepipe steel were investigated. The corrosion rate of steel was affected by test solution chemistry, oxygen content. The corrosion rate of steel decreased in a high NaCl content solution and increased with the addition of oxygen in a low pH condition. No influence of flow rate on corrosion rate of steel was observed between 1m/s and 10m/s. With addition of 0.5% Cr, the corrosion rate decreased and no mesa attack was observed in any conditions. The linepipe steel with the Cr content of 0.5% proved to have excellent properties in various wet CO2 environments.
