This work presents the electrochemical results obtained during the study of the corrosion of X52, X60, X65 and X70 pipeline steel samples, immersed in a 3%wt NaCl solution saturated with CO2 at 20°C under static and controlled turbulent flow conditions. In order to control the hydrodynamic conditions of the system, a rotating cylinder electrode, RCE, was used during the experimentation. Electrochemical techniques, such as: Linear Polarization Resistance, LPR, and polarization curves were used to determine the effect of turbulent flow upon the corrosion kinetics of the different steels studied.
