成品油长输管道完整性评价与维修响应

Integrity Evaluation and Maintenance Response of Long Distance Oil Product Pipeline

为评估成品油输油管道安全状态,制定合理的维修维护计划和管理措施,以某成品油输油管道的检测数据为例,分析了该管道金属损失点沿管道里程和焊缝的分布规律,评估了管道当前剩余强度,预测了管道未来完整性状态,提出了缺隐点维修响应计划和再检测时间。结果表明:该管道检测里程5.9~6.1 km之间存在外部金属损失聚集现象,5处金属损失点应立即修复,80处金属损失点需在5年内完成修复,建议再次检测周期为5年,最迟不超过8年。

In order to assess the safety status of the oil pipeline,formulate reasonable maintenance and maintenance plans and management measures,taking an oil product pipeline as an example,the distribution rule of the metal loss points along the pipeline mileage and weld line is analyzed,the current residual strength of the pipeline is evaluated,the future integrity of the pipeline is predicted,and the maintenance plan and reinspection time of the defect point are put forward. The results show that an external metal loss accumulation phenomenon exists in the pipeline mileage of 5. 9-6. 1 km,5 metal loss points should be repaired immediately,and 80 metal loss points need to be completed within 5 years. The reinspection period is 5 years,at most 8 years.
