Corrosion Predictions in oil transportation

Corrosion Predictions

CO2 corrosion of carbon steel used in oil production and transportation, when liquid water is present, is influenced by a large number of parameters, some of which are listed below:

  • Temperature;

  • CO2 partial pressure;

  • Flow (flow regime and velocity);

  • pH;

  • Concentration of dissolved corrosion product (FeCO3);

  • Concentration of acetic acid;

  • Water wetting;

  • Metal microstructure (welds);
