摘要
完整性评价是管道完整性管理的关键环节之一,是控制管道风险、实施修复决策的重要手段。为准确判定柴北缘输气管道管体缺陷的具体状况,利用PIAPlus(管道完整性评价软件)对该管道的两次内检测结果进行了金属损失、焊缝缺陷、凹陷等缺陷数据的系统评价。依据完整性评价的结果并通过开挖验证,对管道缺陷提出了有针对性的维修维护、再检测计划和安全运行建议,为管道安全平稳运行提供了重要依据。
Integrity evaluation is one of key links in pipeline integrity management. It is an important means to control pipeline risks and implement restoration decisions. PIAPlus(Pipeline Integrity Evaluation Software) played a significant role in detecting metal loss defects and weld defects accurately of gas pipeline in Chaibeiyuan. According to the results of integrity evaluation based on PIAPlus and excavation verification, the targeted maintenance and repair, re-inspection plan for pipeline defects were suggested, an important basis for the safe and stable pipeline operation were provided.
