摘要
完整性评价是长输天然气管道管理的核心,对管道进行完整性评价应优先采用内检测数据。通过开挖验证对检测数据进行评价,确认数据置信度;基于内检测数据对管道开展完整性评价,科学制定缺陷维修计划。
Integrity assessment is the core part of gas transmission pipeline management,ILI data should be given priority for integrity assessment.Confidence coefficient confirmed by dig up verification.Integrity assessment been performed based on ILI data,make feature maintenance plan scientifically.
