Abstract EN
The effect of time (or corrosion products formation) on corrosion rates of carbon steel pipe in aerated 0.1N NaCl solution under turbulent flow conditions is investigated.
Tests are conducted using electrochemical polarization technique by determining the limiting current density of oxygen reduction in Reynolds number range of 15000 to 110000 and temperature range of 30 to 60oC.
The effect of corrosion products formation on the friction factor is studied and discussed.
Corrosion process is analyzed as a mass transfer operation and the mass transfer theory is employed to express the corrosion rate.
The results are compared with many proposed models particularly those based on the concept of analogy among momentum, heat, and mass transport.
The capability of these models to predict corrosion rates in presence of corrosion products is examined and discussed.
It is found that formation of corrosion products with time decreases the corrosion rate (or mass transfer rate) at low Reynolds number and temperature while it increases the corrosion rate at high Re and temperature.
It increases momentum transport and this increase depends on temperature, Reynolds number, and corrosion rate.
Increasing roughness due to the formation of corrosion products causes overestimation of analogy correlations results by increasing friction factor and decreasing corrosion rate.
