Double Wall Corrugated Pipes, SN 4, 100 mm

Double Wall Corrugated (DWC) HDPE pipes are high-performance piping systems designed with a dual-layer structure: a corrugated outer wall for high structural strength and a smooth inner wall for frictionless fluid flow. Primarily used in underground infrastructure, they serve as a durable, lightweight, and cost-effective alternative to traditional materials like concrete (RCC), cast iron, or solid-wall PVC. Key Specifications Material: High-Density Polyethylene (HDPE), known for high life expectancy (50–100 years) and chemical resistance. Sizes: Diameters typically range from 40 mm to 1,000 mm. Stiffness Classes: Most commonly available in SN4 (4 kN/m²) and SN8 (8 kN/m²) to handle different soil and traffic loads. Standards: Often manufactured as per IS 16098 (P
