| 摘 要： | 利用高温高压反应釜模拟高含硫气田H2S/CO2共存环境,在流动溶液介质中进行腐蚀实验,辅以SEM和XRD,探讨了温度对API-X60管线钢H2S/CO2腐蚀行为的影响.结果表明:随温度的升高X60钢的腐蚀速率先升高后降低,腐蚀形态由局部腐蚀趋于全面腐蚀,高温区有点蚀倾向.低温区形成的腐蚀产物以马基诺矿型晶体(FeS1-...

| Abstract: | Flowing solution environments containing H2S/CO2 were simulated in a high temperature and high pressure autoclave.Corrosion behavior of API-X60 pipeline steels was investigated with scanning electron microscopy(SEM) and X-ray diffraction methodology(XRD).Effects of temperature on corrosion rate and products were discussed.The results show that corrosion rate of X60 steel increases at the beginning and then decreases with temperature increasing,and localized corrosion turns into general corrosion obviously,b... |
