Introduction of HDPE Double-Wall Corrugated Pipe
HDPE (high density polyethylene) double wall corrugated pipe is a composite structure pipe manufactured by advanced co-extrusion technology, and its unique design includes smooth inner wall and corrugated outer wall. This innovative structure gives it both high strength and flexibility, making it the preferred pipe material for modern municipal engineering, השקיה חקלאית, industrial drainage and other fields.
Product structure Features
Double-layer composite structure: הקיר הפנימי חלק (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℃ (תקן ASTM D256)
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 שנים
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)
