长输天然气管道防腐补口施工质量控制

摘要

防腐补口是长输天然气管道防腐的一个重要环节，为了保证管道防腐补口的质量，需要控制好表面处理、底漆应用、热收缩带安装等施工过程。文中探讨了各个施工过程中质量控制的方法和措施。%It is an important link to apply anticorrosion coatings on the field joints of long-distance natural gas transmission pipelines. In order to ensure the anticorrosion quality, which is needed to control the construction process, including surface preparation, primer application and heat shrink sleeves installation, etc. In the paper, it is mainly described of the quality control methods and measures in the construction process.
