HDPE silicon core pipe is a specialized protective sleeve for optical cables, made using a three-layer co extrusion composite process. It is composed of a high-density polyethylene outer layer and a silicone lubricant inner layer. The inner and outer layers are synchronously extruded and tightly integrated, never falling off. The product complies with the national standard GB/T 24456-2009, with a black base and colored identification strips. The coil form can reach a single length of 3000 meters and is suitable for long-distance continuous laying.

The core performance of the product is excellent, with a low friction coefficient of 0.08-0.15 for the silicone lubricating layer on the inner wall. Combined with air blowing cable technology, it can achieve a single cable penetration of 1000-2000 meters, greatly improving construction efficiency; The pipe body has good toughness, and the bending radius is only 10 times of the outer diameter. It is suitable for laying in complex terrain, and is acid and alkali resistant, waterproof and anti-aging. The operating temperature range is -30°C to 80°C, stable and suitable for the whole environment.

As a specialized pipe for communication networks, it is widely used in operator trunk fiber optic cable projects, 5G communication infrastructure construction, and is also suitable for communication networks along highways, railway communication systems, and other transportation routes. It is the preferred supporting pipe for various types of communication fiber optic cable laying.

• The inner wall has its own solid silicon core layer with extremely low friction coefficient.

  The inner wall is permanently lubricated with a silicon core layer, and the friction coefficient of the optical cable is small. It can be blown through the cable for a long distance, and the construction efficiency is greatly improved;
