摘要
介绍了基于埋地钢质管道外检测的综合检测方法与仪器、安全评价方法与相应技术规范。提出了埋地钢质管道综合检测与安全评价的具体步骤和方法,该方法可实现对管道外防腐层破损点和阴极保护状况的检测,并对检测中发现的超标缺陷进行安全评价。对某埋地输气管线进行了综合检测评价,提出了确保管道安全运行应采取的相应措施。
Aimed at detecting the coating defects of buried ferrous pipelines, the combining inspection methods and equipment as well as safety assessment methods and technology criteria have been discussed. The methodologies of the combining inspection and safety assessment for buried pipelines have been put forward, which is available for detection of coating defects and cathodic protection status as well as safety assessment of exceeding defects. It has been applied for a buried gas pipeline and some safety suggestions are given.
