摘要 基于前人对管道疲劳寿命的研究,参考国内外文献,提出了在Paris公式的基础上考虑了管道的运行载荷比,并将其运用到某油气管道的疲劳寿命预测中。计算结果表明,管道的运行载荷比是影响疲劳寿命预测的一个主要原因。同时,该结果可以给管道检测、检修及更换提供依据。 On the basis of existing study on pipeline fatigue life and with reference to the published technical papers both in China and abroad, Paris equation with consideration of the pipeline operation load ratio was proposed and applied in the prediction of fatigue life of an oil and gas pipeline. The calculation results showed that the operation load ratio was an important factor affecting the prediction of fatigue life of pipelines. At the same time, the results can be used as the basis for pipeline monitoring, maintenance and replacement.
