Product Advantages of PVC-U Porous Pipe
The PVC-U Porous Pipe is manufactured from high-quality modified PVC engineering plastics through a one-step extrusion process. It is designed to provide high mechanical strength, reliable durability, and efficient cable protection performance in modern underground infrastructure systems.
High Compressive Strength and Aging Resistance
The PVC-U Porous Pipe offers excellent compressive strength and long-term aging resistance. Under normal installation conditions, no additional foundation or encapsulation is required. It effectively prevents settlement and can safely replace steel pipes when crossing road sections. The material also features flame-retardant and self-extinguishing properties, along with strong corrosion resistance, ensuring a service life exceeding 50 years.
Complete Specifications and Flexible System Integration
The PVC-U Porous Pipe system is available with a full range of matching accessories, including connectors, plugs, straps, and special adhesives. These components support flexible construction and ensure secure and stable system integration across different engineering requirements.
Compact Structure and Efficient Space Utilization
The structural design of the PVC-U Porous Pipe is highly compact, requiring only about 10% of the excavation space compared to cement pipe systems. This significantly reduces underground space occupation, improves urban pipeline planning efficiency, and minimizes disruption to road traffic and municipal construction activities.
Strong Flexibility and Easy Bending Installation
The PVC-U Porous Pipe demonstrates excellent toughness and bending capability. A 6-meter pipe section can achieve a bending chord height of over 1.2 meters, allowing it to easily bypass obstacles and cross existing underground pipelines during installation without additional complex adjustments.
Convenient Construction and Labor Saving
The integrated sheath and sub-conduit design eliminates the need for secondary sub-pipe installation. Cables can be directly pulled after a single laying process, effectively avoiding issues such as deformation, twisting, misalignment, and repeated construction work, thereby improving overall installation efficiency.
Lightweight Structure and Easy Installation
The PVC-U Porous Pipe is lightweight and easy to transport and handle. Its smooth inner wall ensures low friction during cable pulling, while its strong compressive performance allows shallow burial depth of 0.3–0.5 meters. No concrete foundation or encapsulation is required; backfilling with 20 cm of fine sand followed by soil is sufficient, enabling immediate traffic use after installation. Compared with PE or corrugated pipe road crossings, it does not require additional steel pipe reinforcement connections.
