HDPE Double Wall Corrugated Pipe

DN200-800mm | SN4-SN8

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.
