对在役输油管道的X60材料进行了低周疲劳性能测试。拟合得到管道材料的应变-寿命曲线公式,依据管道材料的低周疲劳性能,预测该输油管道的疲劳寿命,为管道的安全维护提供了依据。
X60 material in service pipeline was tested for low cycle fatigue performance. Fitting the strain-life curve formula of the pipe material, predicts the fatigue life of the pipe based on the low-cycle fatigue performance of the pipe material, and provides the basis for the safety maintenance of the pipe.
