CO2-corrosion damage to C-steel and low-alloy steel may take various forms; the major types being pitting, grooving and uniform attack. In particular for tubular and pressure containing components, the significance of such damage on safety and reliability is dependent on its interaction with operational loads, and the potential consequences of the resultant failure mode; e.g. rupture, cracking, pinpoint leakage, buckling. The efficiency of any CO2-corrosion control measures, together with techniques to monitor corrosion control efficiency and confirm integrity of equipment, are also dependent on the mode of CO2-corrosion damage. It is therefore essential that any qualitative or quantitative assessments of fluid corrosivity during design or operation arc related to the potential corrosion mode(s) which apply.
