摘要：

It is impossible to keep petroleum and natural gas transmission pipelines free from defects in the manufacturing, installation and servicing process. The damage might endanger the safety of pipelines and even shorten their service life. Gas or petroleum release due to defects may jeopardise the surrounding ecological environments with associated economic and life costs. Pre-tensile deformation of steel is employed to experimentally simulate the influence of dents on the fatigue life. The fatigue life of pipeline steel with defects includes two parts: fatigue crack initiation life and fatigue crack propagation life. In the present study, experimental investigations were carried out on the fatigue characteristics of X60 pipeline steel after different degrees of pre-tension deformation (5%, 10% and 15%). The result is expected to be beneficial to the understanding of the effect of damage on the safety of pipelines and fatigue life prediction.
