⭐ Technical Description
1. Hygiene & Safety Performance
Antibacterial Protection
Nano-antibacterial technology effectively eliminates 650+ types of bacteria, including E. coli and Staphylococcus aureus (kill rate ≥ 99%).
Complies with GB/T 17219-2001 standards for drinking water safety.
Non-toxic & Environment-friendly
Made from safe, non-toxic materials suitable for potable water, drainage systems,
and gas transmission.
2. Structural & Durability Performance
High Pressure Resistance
Steel wire reinforcement provides pressure strength comparable to steel pipes (working pressure 1.6–2.5 MPa).
Excellent resistance to Rapid Crack Propagation (RCP) and Slow Crack Growth (SCG).
Corrosion & Wear Resistance
HDPE matrix resists acids and alkalis (pH 2–12) with no need for concrete bedding.
Ultra-smooth inner surface (roughness ≤ 0.008) provides 3× wear resistance of steel pipes, boosting flow capacity by 30%.
3. Installation & Seismic Performance
Flexible Design
Minimum bending radius ≤ 20D, allowing adaptation to ground settlement and seismic movement.
Withstands impact loads from vehicle traffic, soil slip, and sudden ground stress.
Easy Installation
Electrofusion welding ensures zero-leakage joints.
Pipe weight is only ¼ of steel pipes, improving installation efficiency by 50%.
4. Economic & Environmental Benefits
50-year design service life with minimal maintenance.
Lower overall cost: no concrete thrust blocks, reduced insulation thickness, and simplified construction.
5. Application Fields
Municipal Engineering
Gas distribution
Potable water and drainage
Sewage systems
Industrial
Petroleum & petrochemical pipelines
Chemical and pharmaceutical media
Power engineering
Mining applications
Agriculture
Irrigation and long-distance water conveyance
Typical Applications
