Effect of CO₂ Partial Pressure on CO₂/H₂S Corrosion of Oil Tube Steels

Abstract:

The CO₂/H₂S corrosion behaviors of oil tube steels N80 and P110 at different CO₂ partial pressure (45psi, 135psi, 225psi, 315psi) were investigated by corrosion tests, corrosion rate calculation and corrosion morphology observation. The results show that at different CO₂ partial pressure, super-serious CO₂/H₂S corrosion occurs on steel N80 and steel P110. With the increase of CO₂ partial pressure, the CO₂/H₂S corrosion rates of both steels increase gradually.
