HDPE Silicon Core Duct for Highway

1. 2000m/roll. 2. corrossion resistance. 3. using life over 100 years. 4. low price and easy to install. Adopt the mode of multi-machine co-extrusion, silicon core layer is synchronizely embedded in the pipe. It will be lubricated and not be stripped forever.The friction coefficient of the inner wall is very small. Optical cable (electric cable) can be repeatedly extracted and tensioned in the pipe. Trough using cable blowing machine, one time blowing length can be 1000 to 2000 meter under normal conditions.Good tightness, waterproof, damp-proof, can avoid the damage by rodent animals.With great ring stiffness and toughness. In construction, its bending radius should not be less than 10 times of the external diameter of the pipe.Aging-resistant, anticorrosion of chemicals. With long service life, and will not deteriorate within 50 years in the earth.Good weather resistant ability, and its suitable temperature scope is from -40°C to 100°C.Convenient in construction. This will save time and the project cost is only 30% of the PVC pipe.
