摘要
文中通过粘弹体防腐胶带与热收缩压敏带复合结构在唐山LNG外输管道工程中的应用,介绍了粘弹体加热收缩压敏带复合补口结构的施工方法和检测方法,对这种补口方法现场出现的问题进行分析解决,并将该补口方法与传统的热收缩套补口方法进行了对比,分析2种补口方法的优缺点,得出了比较结果,提出了对粘弹体结构的建议。
Through the application of the combined structure of a viscoelastic corrosion tape and g shirinkabie pressure-sensi- tive tape to the Tangshan outside pipeline engineering, this paper introduces a fresh mending construction method and a fresh in- spection methods, and analyzes to solve the problems with this mending method in the construction site. In addition, it compares the new mending method with the traditional heat-shrinkable mending method and analyzes the advantages and disadaraages ot the two mending methods and obtained a result of comparison of the two methods. It brings forward recommendations for a better viscoelastic body structure.
