摘要
对目前城市埋地钢质管道外覆盖层安全质量状况分级评价现状、分级等级以及分级评价指标进行了探讨和总结 ,提出了分级级别划分的方法 ,给出了用电流衰减法对石油沥青进行分级的参数和部分具体数值 。
The summary of the classification assessment methodology of the safety quality for the protective coating of the buried steel pipelines at home and abroad was discussed.The class level and classification method as well as the assessment indicator was given.It also presented the parameters and the level value of the classification assessment for the petroleum asphaltum coating by using AC/DC Current Attenuation Survey.Predicated the research themes about assessment methodology for the classification in future.
