HDPE Double Wall Corrugated Pipe

DN200-DN800

HDPE Double Wall Corrugated Pipe features a unique structure with smooth inner wall for optimal flow characteristics and corrugated outer wall for enhanced structural strength. ## Product Structure The double wall design provides the best of both worlds: smooth inner surface minimizes friction and prevents sediment buildup, while the corrugated outer wall delivers excellent ring stiffness at reduced material weight. ## Key Advantages - **Superior Flow**: Smooth inner wall reduces hydraulic resistance by up to 30% compared to concrete pipes - **High Strength-to-Weight Ratio**: Lighter than concrete yet maintains structural integrity - **Corrosion Free**: HDPE material eliminates corrosion concerns - **Easy Installation**: Lightweight sections reduce installation time and equipment needs ## Quality Assurance Manufactured according to GB/T 19472.1 standard with full quality control and testing documentation available.
