摘要：The rupture analysis of lubricating oil pipe has been conducted through chemical composition analysis, metallographic analysis and fracture analysis. The analysis results show that there are machining defects and bidirectional vibration at the joint of lubricating oil pipe, which leads to fatigue fracture.
