DN800 SN8 HDPE Double-Wall Corrugated Pipeis an extra-large diameter piping solution with 800mm nominal diameter and SN8 ring stiffness, made from high-density polyethylene. It is widely used in major municipal drainage (e.g., urban main stormwater lines), large-scale water conservancy projects (e.g., canal auxiliary drainage), and wastewater treatment plant outfalls, where maximum flow and ground stability are essential.
A key advantage ofDN800 SN8 HDPE Double-Wall Corrugated Pipeis its exceptional flow capacity. The 800mm diameter handles large-scale water discharge (e.g., urban flood prevention), while the SN8 rating withstands heavy ground loads from infrastructure construction.
DN800 SN8 HDPE Double-Wall Corrugated Pipefurther offers durability and installation flexibility. It is corrosion-resistant to wastewater, saltwater, and soil chemicals, and its lightweight design (compared to concrete) reduces transportation and installation costs. It can be joined quickly with heat fusion, ensuring leak-proof connections. Whether used for urban flood control drains or water conservancy projects, it delivers reliable, long-term performance.
