PVC-U Underground Communication Pipe
Durable, Low-Friction Conduit for Underground Telecommunication Networks
Diameter Range:DN40–DN250
Connection:Solvent Socket · Customized
Applications:Telecommunication · Optical Fiber · Cable Protection
Customization:Diameter · Pressure Rating · Connection · Color
Product Description:
PVC-U Underground Communication Pipe is designed for buried telecommunication and cable protection systems. It provides electrical insulation, flame retardance and corrosion resistance, while its smooth internal surface reduces friction for easier cable and optical fiber installation. High compressive and impact resistance supports reliable long-term performance in underground applications.
