The PVC-U seven-hole pipe adopts the innovative design of plum blossom-shaped porous structure, which is specially designed for communication network, broadcasting and TV and comprehensive pipeline corridor projects to provide efficient cable protection solutions. The product improves impact resistance through high toughness modification technology, ensures long-term buried stability through anti-leakage sealing process, and achieves UL94-V0 flame retardant performance to effectively reduce fire hazards. The standardized interfaces are suitable for a variety of construction environments, supporting quick splicing and layered wiring management, significantly improving construction efficiency. The inner wall adopts nano-lubrication coating to reduce cable penetration resistance, the outer wall reinforcing structure to resist soil pressure, high toughness to ensure the safety of transportation and installation, anti-leakage to extend the service life, and layered wiring to optimize the space utilization rate.PVC-U seven-hole pipe is widely used in the construction of smart cities, transportation hubs and data centers through the production process of lead-free formulations in line with the European Union's RoHS directive on environmental protection, and it is the ideal choice of the modern communications infrastructure. PVC-U seven-hole pipe continues to provide technical support for the reliability and scalability of the pipe network system by virtue of its flame-retardant and standardized interface advantages.
