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”。
