Introduction of HDPE Double-Wall Corrugated Pipe

HDPE (polietilen visoke gustine) 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, poljoprivredno navodnjavanje, industrial drainage and other fields.

Product structure Features

Double-layer composite structure: unutrašnji zid je gladak (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)

Detalji o HDPE Double-Wall Corrugated Pipe

1. Excellent physical properties

Čvrstoća na pritisak: SN8 grade products can withstand a pressure of ≥8000N/m², ekvivalentno 4 meters of soil cover load

Otpornost na udar: Impact strength ≥30kJ/m² at 23℃ (ASTM D256 standard)

Fleksibilnost: radijus savijanja može doseći 20-25 puta prečnik cevi (DN300 pipe minimum bending radius of 6 metara)

2. Dug radni vek

Laboratory accelerated aging tests show that the service life can reach more than 50 godine

Uv resistant formula (2.5-3% carbon black masterbatch added) ensures outdoor performance

3. Environmental protection and economic benefits

Težina je samo 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)
