1、重量轻、同规格下重量仅为钢管重量的1/3，拆装和搬运方便。
1. It is light in weight and only 1 / 3 of the weight of steel pipe under the same specification, so it is convenient for disassembly and handling.
2、管道韧性好、抗冲击强度高，受到强外力冲击时瞬间变形，吸收大量冲击能量，然后迅速恢复原来形状，为公路隧道施工逃生应急救援提供了极为安全可靠的保障。
2. The pipeline has good toughness and high impact strength. When it is impacted by strong external force, it will deform instantaneously, absorb a lot of impact energy, and then quickly restore its original shape, providing a very safe and reliable guarantee for emergency rescue of highway tunnel construction.
3、管道环刚度高、耐压性好、不易变形，在隧道施工中发生坍塌时，承压能力和抗环境破坏能力远远超过一般管道。
3. The rigidity of the pipe ring is high, the pressure resistance is good, and it is not easy to deform. When the collapse occurs in the tunnel construction, the pressure bearing capacity and the environmental damage resistance capacity are far higher than the general pipeline.
4、耐磨损、抗老化，可长时间重复使用。
4, wear resistance, anti-aging, can be used for a long time.
5、比以往钢管管壁更光滑，摩擦系数为新钢管的6分之1
5. The wall of the steel pipe is smoother than the previous one, and the friction coefficient is 1 / 6 of the new one.
