摘要
管道完整性评价是在役管道完整性管理的重要组成部分,检测技术则是完整性评价的重要环节。本文提出了采用外腐蚀直接评价方法进行管道外覆盖层检测及完整性评价的方法和步骤,并对各种检测方法的特点及选用原则进行了探讨,上述方法可以用于埋地钢质燃气管道的综合检测及完整性评价。
Integrity Assessment, which depends on inspection technology, for urban underground steeliness gas pipelines is a primary part of integrity managing for on-line pipelines. With the view to pipeline external corrosion direct assessment methodology,the methods and processes for pipeline inspection and integrity assessment are put forward. The characteristics and fundamental rules have been extensive studied for the existing pipeline inspection. So, it is available for synthetic inspection and integrity assessment for underground steeliness gas pipelines.
