Abstract：Flowing wet gas environments containing H2S/CO2 were simulated in a high temperature and high pressure autoclave.Corrosion behaviors of API-X52 and API-X60 pipeline steels were investigated with Scanning Electron Microscopy(SEM)and X-ray Diffraction methodology(XRD).Effects of high H2S partial pressure on corrosion rate and products were discussed.Corrosion rates of both steels increased with the H2S partial pressure increasing in wet gas,and the corrosion rate of X60 was appreciably higher than that of X52.Localized corrosion was obviously observed when the H2S partial pressure up to 2.0 MPa.The corrosion process was controlled by H2S and mackinawite(FeS1-x)was the dominant corrosion product.Hydrogen blistering and hydrogen-induced cracking were also occurred in X60 in wet gas.
