摘要
采用失效评定图技术分析了油气长输管道特别是高强度大口径管道环焊缝不同强度匹配形式对管道极限承载能力以及抗断性能的影响。以西气东输管道为例,计算分析了环焊缝不同强度匹配对管道抗断能力的要求。最后综合各种因素分析了西气东输管道应采用的环焊缝匹配工艺。
The effect of girth weld strength match on the limit load and fracture resistance of high-grade, large diameter pipelines was analyzed with failure analysis diagram (FAD) method. The West-East Pipeline, the largest pipeline in China up to now, was taken as an example to calculate the fracture resistances when assumed with different strength match ratios. The possible girth weld match procedure for the pipeline is discussed too.
