BACKGROUND OF CO2 CORROSION - idc-online

CO2 corrosion or sweet corrosion is the corrosion of carbon and low-alloy steel by carbonic acid and its derivatives.Carbonic acid is formed by gaseous carbon dioxide first dissolving into water,and then reacting to it.There are three main types of CO2 induced corrosion in pipelines Pitting corrosion Mesa-Type Attack Flow-Induced Localized CorrosionAPI 5CT L80 13Cr Corrosion Resistant Stainless Steel Steel grades for severe corrosive environments In most conditions when the partial pressure of CO2 is above 30psi,carbon steels present high corrosion rates.Steel grades alloyed with high contents of Chromium (Cr),Molybdenum (Mo) and Nickel (Ni) are able to effectively resist corrosion.We manufacture 13% Chromium tubular products in our mills.99031 SIMULATION OF CO2 / H2S CORROSION USING A model has been developed for calculating the rates of general corrosion of carbon steel and 13%Cr steel in aqueous systems containing carbon dioxide,hydrogen sulfide and other components.The model combines a comprehensive thermodynamic speciation module with electrochemical computations based on the mixed-potential theory.
