HDPE silicon core pipe

HDPE silicon core pipe is a new type of composite pipe with silicon colloid solid lubricant on the inner wall, which is called silicon pipe for short. With good sealing performance, chemical corrosion resistance and low engineering cost, it is widely used in optical cable communication network systems such as highways and railways. It is extruded and compounded by three plastic extruders at the same time. The main raw material is high-density polyethylene, and the core layer is silicon colloid, a solid lubricant with the lowest friction coefficient. It is widely used in optical cable communication network system. Main advantages of HDPE silicon core pipe:

HDPE silicon core pipe

HDPE silicon core pipe is a new type of composite pipe with silicon colloid solid lubricant on the inner wall, which is called silicon pipe for short. With good sealing performance, chemical corrosion resistance and low engineering cost, it is widely used in optical cable communication network systems such as highways and railways. It is extruded and compounded by three plastic extruders at the same time. The main raw material is high-density polyethylene, and the core layer is silicon colloid, a solid lubricant with the lowest friction coefficient. It is widely used in optical cable communication network system. Main advantages of HDPE silicon core pipe:

A. The inner wall is solid lubricant with small sliding resistance, which can blow the optical cable to a distance of 2000 meters without breaking; Moreover, the optical cable can be repeatedly extracted and blown, and the self-lubricating characteristics of the inner wall have no change;

B. High mechanical strength, good resistance to high and low temperature, good resistance to chemical corrosion, long service life, no need for additional protection, one HDPL silicon core tube can complete all protection tasks of optical cable.

C. It has good flexibility and can adapt to the slope changes of the terrain, so it can save a lot of investment. Another advantage of good flexibility is that it has strong resistance to external forces, such as earthquakes.

D. The length of the pipeline is 2000 meters, and 90% of the manhole (hand hole) can be dug less than other optical fiber protective casing, which can save up to 50% of the total project cost, which is the biggest competitive advantage of this product.
