The Double-Wall Corrugated Pipe Extrusion Line is a high-performance industrial system designed for manufacturing HDPE double-wall corrugated pipes (ID: 50-250mm) with exceptional acid resistance, flame retardancy, and seismic resilience. Ideal for agricultural drainage, green infrastructure, and water/sewerage networks, these pipes withstand temperatures from -40°C to 60°C and offer a 50-year service life. Featuring bimetal screw barrels for stable extrusion and low-resistance designs for high flow rates, this line produces eco-friendly drainage pipes that replace traditional concrete and pipes. With energy-efficient operation and easy installation, it is a cost-effective solution for soil improvement, drought prevention, and environmental protection projects.
