摘要
含缺陷压力管线经缺陷评定后 ,其疲劳寿命的估计具有重要的工程意义。将整个含缺陷压力管线作为一个整体 ,分析了含缺陷压力管线的疲劳裂纹扩展特点 。
The computation of fatigue life is very important to the pressure pipeline containing defects after the safe assessment was made. In this paper, the character of fatigue crack growth on pressure pipeline was analyzed, and then the computation method of fatigue life of pressure pipeline containing defects was proposed.
