⭐Technical Description
Polyethylene (PE) pressure pipes are designed for reliable water supply performance under demanding conditions. The pipes offer high tensile strength, excellent elasticity, superior resistance to chemical corrosion, and stable hydraulic characteristics. Fusion welding (butt fusion, electrofusion, socket fusion) ensures high-strength, permanent, leak-free joints.
As a drafting company of the national SRCP standard, we adopt strict production control and full-process inspection to guarantee dimensional accuracy, long-term stability, and compliance with ISO 4427, EN 12201, and other international standards.
⭐Technical Advantages
Designed for PN6–PN16 working pressure range
Smooth internal surface (n ≤ 0.009) for enhanced hydraulic efficiency
Excellent resistance to soil movement, vibration, and impact
UV-stabilized for outdoor installation
50-year design life under rated conditions
Available in coils (≤ DN110) and straight pipes (6m/12m)
⭐Recommended Application Fields
Civil water transmission
Potable water distribution
Industrial pipelines
Irrigation and agricultural systems
Trenchless installation projects (HDD, sliplining)
Rural water supply and infrastructure renewal
