The HDPE double-wall corrugated pipe (High-Density Polyethylene Double-Wall Corrugated Pipe) is a novel pipeline material manufactured from high-density polyethylene, featuring a unique dual-layer structural design.
Key Features:
Structural advantages: The outer wall features corrugated reinforcement for enhanced ring stiffness, while the inner wall is smooth; the hollow layer reduces weight and provides high compressive strength. Physical properties: Corrosion-resistant, resistant to low temperatures (-70°C brittle temperature), and highly impact-resistant, with a service life exceeding 50 years. Construction convenience: Lightweight (only 93% of cement pipes), quick installation, minimal requirements for trench bottom conditions, and suitability for ground settlement.
