摘　　要：针对在役3PE管道热收缩带补口失效修复问题,提出了3PE管道补口修复材料的选择原则。对采用热收缩带、热烤压敏胶带、粘弹体胶带、冷缠胶带、液体聚氨酯涂料、无溶剂液态环氧涂料进行补口修复进行了可行性分析。选用热烤压敏胶带、粘弹体胶带、冷缠胶带、液体聚氨酯涂料、无溶剂液态环氧涂料在高温、常温及低温在役管道进行了现场修复试验,通过对修复点的跟踪开挖测试,得到了在役3PE管道补口修复适用技术。With regard to the problem in joint failure repair,with the heat shrinkable tape on in-service 3PE pipe,the material selection rules are presented.Viability analyses are made of various kinds of tapes,such as the heat shrinkable tape,the thermal pressure sensitive adhesive tape,the adhesive elastic tape and the cold winding adhesive tape,and of the fluid polyurethane paint and solvent-free liquid paint.Filed application experiments were conducted with the abovementioned materials at a high temperature,a normal temperature and a low temperature respectively.Digging results for these repair parts were obtained,which reveals the repair technique for in-service 3PE pipe joint.
