Corrugated HDPE Pipe with Steel Reinforcement for Subsurface Drainage and French Drains. Steel Reinforcement: Combines high-strength steel belts with HDPE for superior compression and impact resistance. High Compression Resistance: Enhanced ring stiffness (Sn8-Sn16) adapts to complex geological conditions. Superior Hydraulic Efficiency: Smooth inner wall increases flow capacity by over 40% compared to concrete pipes. Customizable Dimensions: Available in lengths of 5.8m, 9m, 11.8m or fully customized to project needs. Wide Diameter Range: Nominal ID ranges from 200mm to 2600mm for diverse drainage applications. Excellent Chemical Resistance: Resistant to acids, alkalis, and salts, ideal for wastewater discharge. Easy Installation: Lightweight and flexible design allows installation without seasonal limitations. Long Service Life: Outstanding abrasion resistance minimizes scaling for longer durability.
