摘要/Abstract

摘要： 为研究轴向应力对腐蚀缺陷管道极限内压的影响,采取非线性有限元分析法,建立轴向应力和内压作用下的管道三维有限元模型,利用文献中的爆破试验数据验证模型后,分析不同腐蚀缺陷参数、材料参数在轴向压应力和轴向拉应力作用下对应的管道极限内压变化情况,提出轴向应力作用下的腐蚀缺陷管道极限内压预测公式。结果表明:轴向压应力会造成缺陷管道极限内压降低,极限内压受轴向应力影响程度不同,缺陷几何尺寸越小,轴向应力对管道极限内压的作用效果越明显;轴向拉应力会造成管道极限内压略微升高,且轴向应力越大,作用效果越明显;不同腐蚀缺陷几何尺寸的管道屈服强度越高,轴向应力作用效果越不明显;所建立的极限内压预测公式,预测精度较好,可用于腐蚀缺陷管道极限内压的计算。

Abstract: In order to study the influence of axial stress on ultimate internal pressure of corroded pipelines, a three-dimensional finite element model of pipeline was established. The model was verified by the blast test data from the literature. The changes of ultimate internal pressure of pipelines under axial compressive stress and axial tensile stress with different corrosion defect parameters and material parameters were analyzed, and the results were based on the finite element simulation. The formula to predict the ultimate internal pressure of corroded pipeline under axial stress was put forward. The results show that the axial compressive stress will lead to reduction of the ultimate internal pressure, that the effect of axial stress on the ultimate internal pressure of pipelines varies and the smaller the defect size is, the more obvious the effect will be, that the axial tensile stress will result in a slightly higher ultimate internal pressure, and the greater the axial stress is, the more obvious the effect will be, that the higher the yield strength of pipelines with different geometric sizes of corrosion defects is, the less obvious the effect of axial stress will be, and that the established ultimate internal pressure formula is accurate, and it can be used for predicting the ultimate internal pressure of corroded pipelines.
