摘　　要：本文简介了风险评估技术的原理和方法,以及该技术在石化储运类管线中的应用,采用半定量风险评估方法进行风险分析。根据风险分析的结果,此次所评估的储运类管线的主要失效模式为外部腐蚀,其内部腐蚀减薄和应力腐蚀的敏感性较低。通过应力腐蚀试验,试验结果也验证了这些管道的抗应力腐蚀性能良好。In this paper,Briefly Depicting the principle and method of RBI,and the application in petrochemicals at the same time.Taking storage and transportation pipe example, applicate semiquantitative analysis.According to the result of RBI ,the major failute mechanism is outside corrosion, however,inside corrosion and SSCC sensitive is lower.SSCC test also indicates that storage and transportation piping has better resistance to SSCC.

关 键 词：储运类管线 风险评估技术 试验研究
