Product structure Features
Double-layer composite structure: the inner wall is smooth (thickness 1.5-3mm) to ensure water flow efficiency, and the outer wall is corrugated (peak height 15-40mm) to enhance the ring stiffness
Material science breakthrough: Using PE100 grade primary high density polyethylene, density ≥0.95g/cm³, melting index 0.3-0.5g/10min
Innovative connection system: double selection of plug and insert electrothermic connection (DN200-DN1200) and clamp connection (DN150 or less)
Details of HDPE Double-Wall Corrugated Pipe
1. Excellent physical properties
Compressive strength: SN8 grade products can withstand a pressure of ≥8000N/m², equivalent to 4 meters of soil cover load
Impact resistance: Impact strength ≥30kJ/m² at 23℃ (ASTM D256 standard)
Flexibility: the bending radius can reach 20-25 times the diameter of the pipe (DN300 pipe minimum bending radius of 6 meters)
2. Long service life
Laboratory accelerated aging tests show that the service life can reach more than 50 years
Uv resistant formula (2.5-3% carbon black masterbatch added) ensures outdoor performance
3. Environmental protection and economic benefits
The weight is only 1/8 of the concrete pipe, reducing the transportation and installation cost by more than 40%
The inner wall friction coefficient is 0.009 (27% lower than the concrete pipe), and the lifting velocity is 15-20%
4. Intelligent installation system
Smart fitting with RFID chip (optional)
Millimeter-level docking accuracy with dedicated welding equipment (output power 4-10kW)
