A valid Computational Fluid Dynamics (CFD) based approach for corrosion rate calculation can be a strong tool in identifying erosion-corrosion or flow-induced corrosion hot spots. Damage tends to occur in geometries such as chokes elbows and jumpers that are typically encountered in oil and gas production systems. A large number of parameters can impact the metal-loss mechanism: flow conditions solution chemistry temperature pressure and material of the component.Experiments to realistically evaluate the complex conditions encountered during oil and gas production are difficult to design and control. However a CFD based approach provides a powerful tool to link electrochemical and chemical information required for corrosion rate calculations with the mechanical action of the fluid flow. The current study focuses on developing an approach for using CFD in combination with standard corrosion software to calculate corrosion rate. Effect of pH carbon dioxide partial pressure temperature and Reynolds number on ionic species flux to the pipe surface was investigated. Furthermore the calculated corrosion rates were compared to the predictions of available mechanistic models to develop confidence in the approach.

The NORSOK M-506 is an empirical model based on experiments undertaken in a single phase water flow loop. The data is from experiments with low content of iron ions in the water phase, and the model is thus regarded to give a fair representation of the maximum corrosion rate in a CO2 corrosion controlled system.
