DN400 SN8 HDPE Double-Wall Corrugated Pipeis a robust piping solution with a 400mm nominal diameter and SN8 ring stiffness, crafted from HDPE. It is widely used in medium-sized municipal drainage, industrial wastewater discharge (e.g., factory effluent), and suburban stormwater management, where higher flow rates and ground stability are required.
A key advantage ofDN400 SN8 HDPE Double-Wall Corrugated Pipeis its structural efficiency. The SN8 rating handles ground loads from suburban roads or industrial yards, while the double-wall design reduces weight (30% lighter than concrete pipes) for easier transportation and installation.
DN400 SN8 HDPE Double-Wall Corrugated Pipealso excels in durability. It resists corrosion from industrial chemicals and soil salts, and its flexible structure adapts to minor ground settlement without cracking. The smooth inner surface prevents clogging, ensuring consistent wastewater flow. Whether used for factory drainage or suburban stormwater lines, it delivers long-lasting performance.
