| 摘 要： | 以X60双腐蚀缺陷油气管道为研究对象,借助ANSYS软件,分析双腐蚀缺陷半径和缺陷深度对其等效应力和剩余强度的影响。结果表明:随着轴向位置的增加,双腐蚀缺陷管道等效应力在屈服极限与抗拉极限之间变化;随着缺陷半径的增大,剩余强度呈增加的趋势,安全性增强;随着缺陷深度的增大,剩余强度呈减小的趋势,安全性降低。所得结论对于油气管道的腐蚀安全评价有一定的参考意义。

| Abstract: | With the aid of ANSYS software,the effects of the radius and depth of double corrosion defects on the equivalent stress and residual strength of X60 double corrosion defects oil and gas pipeline were investigated.The results show that with the increase of the axial position,the equivalent stress of the pipeline with double corrosion defects changes between the yield limit and the tensile limit;with the increase of the defect radius,the residual strength increases and the safety increases too;with the increase of the defect depth,the residual strength decreases and the safety decreases too.The conclusions are of some reference significance for the safety assessment of the oil and gas pipelines. |
