Huashida provides a high-performance extrusion line for producing HDPE hollow wall winding pipes, with a maximum pipe diameter of up to 4000mm. The system is capable of producing large diameter winding pipes and mine-grade anti-static ventilation pipes. It adopts specialized pipe connection fittings such as electric hot melt belts and heat shrink sleeves, ensuring easy installation and cost-effective construction.

• High ring stiffness and excellent impact strength
• Lightweight construction
• Superior resistance to creep deformation and external pressure
• Excellent corrosion resistance against acids, alkalis, salts, etc.
• Service life of over 50 years

These pipes are widely used in municipal sewage and drainage systems, and are ideal replacements for traditional cement and cast iron pipes due to their low installation cost, easy operation, and fast connection.
