The environmental conditions encountered in oil and gas wells can cause severe corrosion to carbon steel tubing and pipelines and the microstructure and chemical composition of steel are considered to be important variables that affect the resistance of steel to corrosion. Five different pipeline steels with different chemical composition and microstructure were chosen to investigate the effect of their metallurgy on the attributes of formed iron carbonate and related corrosion phenomenathat could lead to localized corrosion.The effect of a high liquid flow rate on a pre-formed iron carbonate corrosion product layer was studied at 80°C pH 6.6 and 1.5 pCO2for each steel. Iron carbonate layersinitially formed on each steel at low shear stress (35 Pa) were exposed to high shear stress (535 Pa) for 3 days. For all tested steels the formed iron carbonate layer reduced the general corrosion rate to less than 0.5 mm/y after 2 days but the increase in shear stress caused locations of film failure (pitting).All steels suffered localized or pitting corrosion but the penetration rates of pitting found in normalized steels was much lower than in Q & T steels.

Keywords: CO2 corrosion shear stress iron carbonate steel microstructure normalized quenched and tempered.
