DN200 SN8 HDPE Double-Wall Corrugated Pipeis a lightweight, high-strength piping solution with a nominal diameter of 200mm and a ring stiffness (SN) of 8kN/m², made from high-density polyethylene (HDPE). It is widely used in residential area drainage, small-scale municipal stormwater systems, and landscaping irrigation, where moderate flow and easy installation are needed.
A key advantage ofDN200 SN8 HDPE Double-Wall Corrugated Pipelies in its balanced performance. The SN8 rating ensures it withstands ground pressure from residential construction, while the double-wall structure combines strength with light weight—simplifying manual installation without heavy equipment.
DN200 SN8 HDPE Double-Wall Corrugated Pipefurther offers durability and cost-effectiveness. It is corrosion-resistant to soil chemicals and wastewater, avoiding rust issues of metal pipes. Its smooth inner wall reduces flow resistance for efficient drainage, and it has good UV resistance for above-ground use. Whether used for neighborhood rainwater discharge or garden drainage, it delivers reliable, low-maintenance performance.
