1,The lining of the silicon core layer is solid, permanent lubricant;
2,The lining of the silicon core layer is pressed by synchronization in high density polyethylene pipe wall, and evenly distributed throughout the pipe wall, not peeling off.
3,The lining of the silicon core layer does not react with water, wash water pipe after an accident.
4,The lining of the silicon core layer and high density polyethylene with the same physical and mechanical properties;
5,Internal friction characteristics of silicon core layer remains the same, cable in the pipe can be extracted repeatedly, blowing method, one can blow cable 1000 m or above
