HDPE Silicon Core Duct is a new-type composite pipe with silicone compound solid lubricant in its inner wall, referred to as silicon tube. It is extruded composited by three plastic extruders and the main raw material is high-density polyethylene. 

 

The core layer is solid silicone lubricant , which has the lowest coefficient of friction .The silicon core of inner wall is solid and to be a permanent lubricants. And the friction characteristics of silicon core will remain unchanged so that the cable can be extracted repeatedly in pipe, and It has the same physical and mechanical properties as the HDPE, so it will not peel and with the same life as HDPE. 

 

The pipe is convenient in construction and greatly reduce the project cost. Neither need the jacket pipe nor subduct, the cables can through directly in silicon core pipe . Each (cycle) silicon core pipe can be made of any length, since the length is generally ***0 meters, then the men- well can be set every 1,**0 m. Using the air blowing to wear cables, so it only need *5 minutes each 1,**0 meters .It is widely used in optical cable communication network system.

 

The silicon core layer will not react with water and can be washed with water after the accident occurred. And radius of curvature for silicon core pipe is small (ten times than its diameter.) , if meet the bend and the gap when laying, it can be determined with the environment without doing any treatment.

 

 

 

1.Tensile resistance, compression resistance, impact resistance, and need no subduct ;

2.A low friction smooth surface make it easy to draw or blow the cable repeatedly;

3.Good tightness, waterproof, can avoid the damage by rodent animals;

4.Weathering resistance and can be used between **0°C to *0°C;

5.Aging resistance, long service life and can work for over *0 years underground.
