从对国内某弯管厂生产的川气东送管道工程用Φ1016mm×26.2mm感应加热弯管及其母管的主要理化性能进行的分析比较中发现,感应加热弯管及其母管的主要性能均值明显高于该管道工程技术标准的要求;所制得的弯管较母管强度下降,韧性上升,塑性略有增加;弯管不同部位的性能变化也有一定的差异。 From the analysis and comparison of the main physical and chemical properties of Φ1016mm × 26.2mm induction heating elbow and its main pipe produced by a bent pipe factory in China, it is found that the main properties of induction heating elbow and its main pipe The average value is significantly higher than the requirements of the pipeline engineering standards; the resulting bend than the decrease in the strength of the mother tube, ductility increased slightly increased plasticity; performance changes in different parts of the elbow also have some differences.
