西气东输工程实施十多年来，埋地管道得到了广泛使用。根据 TSG D7003—2010《压力管道定期检验规则———长输（油气）管道》和 TSG D7004—2010《压力管道定期检验规则———公用管道》的要求，为了保证埋地钢制管道的安全运行，需对埋地钢制管道进行定期检验，包括年度检查、全面检验和合于使用评价。目前，国内检验及合于使用评价工作处于起步阶段。以某使用9 a 的埋地天然气管道为例，对其进行了全面检验及合于使用评价，为埋地钢制管道的安全检验工程应用提供了参考。

Since the West-to-East Gas Pipeline Project has been implemented in about 10 years, the buried pipelines are widely used.According to TSG D7003—2010 “Pressure Piping Periodic Inspection Regulation ———Long Distance (Oil and Gas )Pipeline”and TSG D7004—2010 “Pres-sure Piping Periodic Inspection Regulation ———Utility Pipeline ”,it is necessary to perform the regular inspection of buried steel pipelines in order to ensure the safety of that,annual inspec-tions,comprehensive inspection and fitness for service are included in the regular inspection.At present,the project is in its infancy.A city buried gas pipeline which was used in about 9 years is taken into consideration,then,the practice of comprehensive inspection and fitness for service is performed.It provides a reference for the engineering application of buried steel pipeline inspection.
