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。 This article briefly introduces the principle and method of risk assessment technology, and the application of the technology in petrochemical storage and transportation pipeline. It uses semi-quantitative risk assessment method to conduct risk analysis. According to the result of the risk analysis, the main failure mode of the pipeline for storage and transportation evaluation evaluated by this time is external corrosion, and its sensitivity to internal corrosion thinning and stress corrosion is relatively low. Through the stress corrosion test, the test results also verify that these pipes have good stress corrosion resistance.
