The silicon core layer on the inner wall of HDPE silicon core pipe is solid and serves as a permanent lubricant, maintaining a constant friction coefficient. Cables can be repeatedly pulled through the pipe;
2. The silicon core layer on the inner wall of HDPE silicon core pipe is co-extruded into the high-density polyethylene pipe wall and evenly distributed across the entire inner wall. The silicon core layer shares the same physical and mechanical properties as the high-density polyethylene, preventing peeling or separation, and has the same lifespan as the silicon pipe;
3. The silicon core layer on the inner wall of HDPE silicon core pipe does not react with water. In case of accidents, the pipe can be flushed with water;
4. HDPE silicon core pipe has a small bending radius (ten times its outer diameter). When laying the pipe, it can adapt to bends and elevation changes according to the terrain without any additional treatment or the need for manholes for transitions;
5. Each length (or coil) of HDPE silicon core pipe can be manufactured to any length. Generally, for ease of transportation and construction, each length (or coil) of silicon core pipe is 2000 meters;
6. HDPE silicon core pipe is easy to construct, significantly reducing engineering costs. The silicon core pipe does not require an outer protective pipe, and cables can be directly blown into the pipe without the need for sub-pipes. Since each coil of HDPE silicon core pipe is typically 2000 meters long, manholes can be placed every 1000 meters. Using air-blowing for cable installation, each 1000-meter section takes only 15 minutes.

Product Appearance
The inner and outer walls of HDPE silicon core pipe should be clean and smooth, free from bubbles, significant scratches, dents, impurities, or uneven coloring. The pipe ends should be cut flat and perpendicular to the pipe axis. The silicon core inner wall should be tightly fused without any separation. The outer wall of the pipe should be clearly marked.

Application Areas of HDPE Silicon Core Pipe: Pipeline systems for outdoor communication cables and optical fibers, public information networks, public transmission systems, cable television networks, and highway communication projects.
