Double Wall Corrugated Pipe Application and Technology

What is Double Wall Corrugated Pipe?

Double wall corrugated pipe is a type of pipe made from thermoplastic materials like HDPE, PP, or PVC. It features a unique structure with a smooth inner wall and a corrugated outer wall. This design provides high ring stiffness and impact resistance while the smooth inner wall minimizes flow resistance. This makes it ideal for a variety of applications such as drainage, sewage systems, agricultural irrigation, and protection of cables. Thanks to its corrosion resistance, lightweight flexibility, and long-lasting performance, it is widely used in demanding environments that require both strength and flexibility.

Core Technical Features of Double Wall Corrugated Pipe

  • 1 Co-Extrusion Technology
    The double wall corrugated pipe is manufactured using advanced co-extrusion technology that ensures perfect bonding between the inner and outer layers. The smooth inner layer reduces flow resistance, while the corrugated outer wall provides high structural strength and crush resistance.
  • 2 Low-Temperature, Low-Pressure Extrusion
    The unique die structure ensures low-temperature, low-pressure extrusion, which results in uniform wall thickness and smooth surfaces. This technology helps enhance the pipe’s chemical resistance and impact strength while maintaining cost-efficiency during production.
  • 3 High-Speed Water Cooling System
    The high-speed water cooling system is integral to the manufacturing process, ensuring that the pipe maintains its shape and stability during the cooling process. The water-cooled corrugator layout ensures a lower center of gravity and higher rigidity, enabling smooth operation and enhanced product consistency.
  • 4 Innovative Mould Design
    The mould’s spiral structure guarantees precise control over extrusion temperature and pressure, making it easy to adjust the inner and outer wall deviations. This allows for quick adjustments without the need to dismantle the water jacket, making production more efficient.

Applications of Double Wall Corrugated Pipe

Plastic double wall corrugated pipe excels in drainage and stormwater management applications due to its unique dual-wall structure. The smooth inner wall minimizes flow resistance while the corrugated outer wall provides exceptional ring stiffness and impact resistance, enabling it to withstand heavy loads with lightweight flexibility. Advanced co-extrusion manufacturing technology ensures perfect bonding between layers, creating pipes that maintain their structural integrity under backfill pressures and dynamic loading conditions. This combination of hydraulic efficiency and mechanical strength makes it the preferred choice for highway drainage, land development projects, and agricultural subsurface drainage systems where both performance and installation efficiency are crucial.

Drainage and Stormwater Management


Plastic double wall corrugated pipe is extensively used in subsurface drainage and stormwater management systems. Its unique structure, featuring a smooth inner wall and a corrugated outer wall, provides exceptional hydraulic efficiency and crush resistance. This makes it an ideal choice for applications such as highway and railway drainage, land development projects, and agricultural field drainage, where reliable long-term performance under soil and traffic loads is critical.​​​​​​​
