| Abstract: | The CO 2/H 2S corrosion behavior of oil tube steels N80 and P110 at different H 2S partial pressure (1.4 kPa,20 kPa,60 kPa,120 kPa) is studied by autoclave,weight loss method and SEM analysis.The results show that the corrosion rate increases at first and then decreases with increasing of H 2S partial pressure.The peaks of corrosion rate appear at 20 kPa of H 2S partial pressure for the two steels. |
