图3 3G防腐胶粘带在石方段上的应用,使用数年后,地面音频检漏测试,漏点数:3-6个/km,比原来500个/km降低了98%。


  该段管线以前采用过热熔沥青、环氧煤沥青玻璃丝布,聚丙烯冷缠胶等防腐层,效果一直不太理想,地面音频检漏平均漏点500个/km,阴保效率较低,是管线腐蚀的重灾区。自从使用了3G防腐胶粘带防腐层后,每年两次地面音频检漏检测,漏点3-6个/km。和原来的各类防腐层相比,在相同的使用年限上,漏点减少了98%。用过3G防腐胶粘带的施工单位对3G防腐胶粘带情有独钟。问他们为什么愿意用3G防腐胶粘带,他们回答:“用其他的带子过一段时间就会出现漏点,出现漏点就得挖开返工,用3G防腐胶粘带不用返工”。
