基于内检测评价的管道安全维修决策
|
摘要
为科学合理地制定管道维修维护计划,研究含腐蚀缺陷管道剩余强度评价方法的估计维修因子(ERF)曲线,分析不同方法的适用性,提出腐蚀速率分段求解和基于边界条件约束的管道安全维修时限概念;依据检测深度、缺陷位置、其他缺陷影响等因素,定性评价凹陷是否可接受;采用SHANNON方法 ERF曲线量化分析含制造缺陷管道的剩余强度;在此基础上,制定不同缺陷的维修决策判定准则,形成一套全新的管道安全维修决策技术;最后,以某管道为例,分析管道的内检测(ILI)数据,验证成套技术的适用性。结果表明:用该套技术能确定管体各类缺陷的安全维修时限和维修响应等级。
To make a scientific and reasonable maintenance decision for pipeline,applicability for different methods for pipeline with corrosion defects was analyzed by means of estimated repair factor( ERF)-curves for different residual strength assessment methods. A concept of pipeline safety maintenance time was performed based on segmented corrosion rate calculation and boundary constraint conditions.Factors including detected depth,defects location and influence from other defects were adopted to assess acceptability of dent qualitatively. The residual strength for pipe with manufacturing defects was analyzed quantitatively by using ERF-curve of SHANNON. On this basis,maintenance decision-making criteria were set for different defects,thus a new safey maintenance decision-making technology was developed for pipeline. Finally,a specific pipeline was taken as example,with analyzing of its ILI data,the feasibility of the technology was verified. The result shows that the technology can be used to determine the safety maintenance time and maintenance response level for different defects of pipeline.
