埋地钢质管道防腐层检测技术的应用

Application of anticorrosion layer inspection techique for buried steel pipelines

地钢质管道在施工过程中经常发生防腐层的机械损伤，在自然环境下管体发生腐蚀也是不可避免的。管道防腐质量直接影响工程使用寿命及运行安全，做好对管道防腐层质量监督，及时发现管道腐蚀问题，是确保工程实体质量的关键环节。介绍了埋地钢质管道防腐层检测技术在辽河油区应用情况，对下一步在辽河油区如何开展埋地钢质管道防腐层检测工作提出了具体而有建设性的意见。对新建埋地钢质管道进行防腐层检测，可以及时发现管道防腐层的损伤，并最终确认防腐层质量，从而保证管道防腐层性能，还可以延长管道的使用寿命，确保管道安全运行。

This paper introduces the application of anticorrosion layer inspection technique for buried steel pipelines in Liaohe Oilfield, brings forward some concrete and constructive proposals about how to carry out the anticorrosion layer inspection for buried steel pipelines in next stage. For newly built pipelines, the inspection of anticorrosion layer can find anticorrosion layer damage and finally determine anticorrosion layer quality, so as to ensure anticorrosion performance of the pipeline and prolong service life of the pipeline.
