Title: Corrosion characteristics of X-60 pipeline steel in acid solution of H_2S and CO_2 under high temperature and high pressure
Abstract: The corrosion characteristics of X-60 pipeline steel under five different high temperatures and in acid solution saturated with H_2S at 2 MPa partial pressure of CO_2 were investigated by SEM,XRD,weight loss method and electron-probe microanalysis.The results show that in the temperature ranges of 90-210 ℃,serious CO_2/H_2S corrosion of X-60 pipeline steel occurs with pitting or pitting corrosion groups at different degrees.With the temperature increasing,the corrosion rate of X-60 pipeline steel shows the tendency of increase-decrease-increase,corrosion products-iron sulfide films are formed on the surfaces of the samples.The microstructure of the steel can affect the corrosion characteristics,the corrosion features on the surface of the X-60 pipeline steel are unique,and to a certain degree,it is the result of the correlating effects of both hydrogen damage and pitting caused by CO_2/H_2S corrosion.
