含裂纹缺陷管道的剩余强度评价

由于油气管道输送介质易燃、易爆和有毒性的特点,在输送过程中一旦发生泄漏,就会迅速扩散、燃烧,甚至爆炸,势必造成人员伤亡和经济损失。因此,防止管道破裂成为油气输送管道安全运行的重要任务,一直受到相关部门的高度关注。

Evaluation on Residual Strength of Pipe With Crack Defects

Therefore, prevention of pipeline rupture as an important task of safe operation of oil and gas pipelines has been highly concerned by the relevant departments.
