- 摘要:
- 在国内输气管道——广东LNG站线项目首次引进试用了目前国际上最新的3PE管道液体环氧补口技术。该补口技术具有涂装过程简单、界面粘结牢固、修补方法容易、检验结果可靠、材料价格较低、能源消耗少、流水作业快、不产生阴极保护屏蔽等特点。文章介绍了相关技术标准的编制过程以及与产品供货和现场施工有关的最低技术要求。
In the gas transportation pipeline construction at Guandong LNG Station, the technique of using liquid epoxy for 3PE anticorrosion pipeline field joints was applied for trial for the first time in our country. Based on the study of mechanism and related field construction technical standard, the characteristics of this new field joint technique are summarized, which include simple coating process, strong interface binding force, easy mend method, reliable inspecting results, lower material price, lower energy consumption, faster flow operation and without cathodic protection shielding. In order to improve this new field joint technique, the primary technical standard is established.2007,06(06): 37-39 收稿日期：2007-4-28分类号：TE973.3作者简介：史航(1958-), 男, 山东人, 高级工程师, 1985年毕业于石油部管道局职工学院, 任副总工程师, 长期从事输油输气管道的设计, 曾担任广东 LNG 站线工程的设计经理.参考文献：
