Abstract: In this article,the SRB test, high temperature and high pressure corrosion test and groove corrosion test for domestic and imported J55 HFW oil pipe were carried out and studied, under condition of changqing luohe water medium. In the SRB corrosion environment, the corrosion rate of domestic and imported J55 HFW oil pipe respectively is 0.042 mm/a and 0.043 mm/a. Under the condition of high temperature, high pressure and carbon dioxide, the corrosion rate of domestic and imported J55 HFW oil pipe respectively is 0.098 mm/a and 0.094 mm/a. Under the condition of luohe water corrosive medium, the groove corrosion sensitive coefficient of domestic and imported J55 HFW oil pipe respectively is 1.15 and 1.13. The results indicated that the corrosion resistance of domestic J55 oil pipe is consistent with that of imported J55 HFW oil pipe under luohe water corrosive medium environment.
