- 高钢级管道的建设和发展极大地促进了中国油气资源的快速、高效配置，但同时也带来环焊缝质量风险等新的突出问题。系统分析高钢级管道可靠性影响因素，并采取有效措施加以控制，已经成为保障油气管道安全平稳运行的重要课题。基于高钢级输气管道环焊缝断裂失效分析结果，聚焦环焊缝质量风险基础技术研究、现场施工作业管理、缺陷成因分析、失效机理认知等多方面问题，从冶金、制板、制管、设计、施工、检验及投产运行全生命周期出发，建立了全生命周期可靠性影响因素识别框架。基于当前制造和施工技术，依据1100×104条钢管化学成分和力学性能数据的统计分析结果，探讨了钢管可靠性的主要影响因素；依据输气站场弯管、管件典型失效案例的分析结果，探讨了管件可靠性的主要影响因素；依据2027组环焊缝性能数据及1683组焊材性能数据，探讨了环焊缝可靠性的主要影响因素。以当前面临的高钢级管道环焊缝失效问题为例，深入分析了焊接接头性能匹配、焊接缺陷、管材成分、焊接工艺、焊接材料等方面存在的问题，并提出针对性的管控措施及研究方向，可为后续高钢级输气管道建设提供技术支撑与决策参考。（图5，表2，参44）
- Abstract:
- The construction and development of high-grade steel pipelines have greatly promoted the rapid and efficient allocation of oil and gas resources in China, but new prominent problems such as quality risk of girth weld are also brought. Systematically analyzing the factors influencing the reliability of high-grade steel pipelines and taking effective control measures have become the important subjects to ensure the safe and stable operation of oil and gas pipelines. Based on results of analysis on fracture failure of high-grade steel pipeline girth weld, the problems such as the basic technological research on quality risk of girth weld, site construction management, defect cause analysis, and failure mechanism cognition were focused, and an identification framework of factors influencing the reliability in full life cycle was established from the aspects of metallurgy, plate-making, piping, design, construction, inspection, commissioning and operation. Besides, the main factors affecting the reliability of steel pipes were discussed based on the current manufacturing and construction technology through the statistical analysis results in terms of the chemical composition and mechanical properties data of 1 100×104 steel pipelines, the main factors affecting the reliability of pipe fittings were discussed based on the analysis results of typical failure cases of pipe bends and fittings in gas stations, and the main factors influencing the reliability of girth welds were also discussed based on the performance data of 2 027 sets of girth welds and 1 683 sets of welded materials. In addition, problems concerning the performance matching of welding joints, weld defects, pipe components, welding process, welding material, etc., were analyzed in depth based on the current problem of girth weld failure of high-grade steel pipeline. Meanwhile, appropriate control measures and the research direction were put forward, which could provide technical support and decision-making reference for the subsequent construction of high-grade steel pipelines.
