| 中文摘要: |
| 由于外部环境及输送介质的影响，油气管道在运行过程中不可避免地会出现腐蚀缺陷，腐蚀处会产生应力集中的现象，从而削弱管道的承压能力。因此，必须对含腐蚀缺陷的管道进行剩余强度及剩余寿命评价，评价结果可以为缺陷管线的维修计划提供重要依据。综述了国内外主要的腐蚀缺陷管道评价规范，分析了不同规范的适用范围。从单个腐蚀和群腐蚀两个方面展开论述，归纳了含腐蚀缺陷管道评价技术的最新研究进展，并介绍了目前的研究热点——群腐蚀缺陷管道剩余强度评价方法以及腐蚀缺陷间相互影响准则（interaction rule）。另外，论述了目前腐蚀管道剩余寿命预测的常用方法，包括灰色预测法以及可靠度函数分析法。最后，总结了腐蚀缺陷管道评价技术研究进展，并对未来的研究工作提出了展望。 |
| 英文摘要: |
| Due to effects of external environment and transmission medium, oil-gas pipelines will inevitably be corroded during the process of operation. Intensive stress appears in corroded parts, which may impair loading capacity of pipelines. Therefore, residual strength and residual life must be evaluated for corroded pipelines, the evaluation results can provide vital basis for maintenance schedule of defective pipelines. First, major evaluation standards for corroded pipelines at home and abroad were summarized, and application scope of these standards was analyzed. Discussion was completed from the aspects of single corrosion and multiple corrosions. Recent research progress of corroded oil-gas pipeline evaluation technology was concluded, and current research highlights-remaining strength evaluation methods of pipelines subject to multiple corrosion defects and interaction rule between corrosion defects were introduced. Besides, popular methods of predicting residual life of corroded pipelines, including gray forecasting method and reliability function analysis method were reviewed. In the end, research progress of corroded oil-gas pipeline evaluation technology was concluded and future study prospects were proposed. |
