Effect of H2S Partial Pressure on CO2/H2S Corrosion of Oil Tube Steels
The CO2/H2S corrosion behaviors of oil tube steels N80 and P110 at different H2S partial pressure (0.2psi, 3psi, 9psi, 18psi) were investigated by autoclave corrosion tests, corrosion rate calculation and corrosion morphology observation. The results show that with the increase of H2S partial pressure the CO2/H2S corrosion rates of both steels increase at first and then decrease after the peaks appear at 3psi H2S.
