摘要:
高压天然气管线脆性断裂往往会导致灾难性事故。回顾了早期国际上脆性断裂止裂的研究成果,对目前我国及国际上管线钢管技术标准中作为重要控制指标的DWTT剪切面积的规定进行了总结,并在脆性断裂止裂理论基础上,分析讨论了我国天然气管道长输管线用高钢级厚壁管线管DWTT技术要求,指出对于现代高强韧性X80厚壁管线钢管,在较低应力水平下使用时,DWTT要求建议为平均值50%SADWTT,另外还提出了管线钢板材DWTT试验温度分析方法和推荐值。
Abstract:
Brittle fracture of highpressure natural gas pipelines always leads to catastrophic accidents. This paper reviews the early international research results on brittle fracture crack arrest. Based on the theory of brittle fracture crack arrest, the technical requirements of DWTT for high grade pipelines with heavy wall thickness used in long distance natural gas pipelines in China are analyzed and discussed. It is pointed out that when the modern high strength and toughness X80 pipe with heavy wall thickness is used at low stress level, the average shear area value of DWTT of the pipe is recommended to be 50% SADWTT. In addition, the temperature analysis method and recommended value of DWTT test for coil or plate are proposed.
