The composite reinforced HPVC double wall corrugated pipe has a hollow circular structure between the inner and outer walls, fully utilizing the principle of I-shaped steel structure. It has the advantages of super strength, super toughness, corrosion resistance, high temperature resistance, convenient construction, and low cost.

        The product uses excavation engineering and can replace pipes such as MPP single wall corrugated pipes, PVC-C power pipes, PVC-U communication pipes, and MPP directly buried pipes. Widely used in various construction fields such as outdoor bridges, tunnels, light rail, airports, subways, venues, real estate, etc.

Product Features：

一、High toughness: tensile strength can reach 40MPa；

二、Temperature resistance: Ordinary plastic pipes have high brittleness, and composite HPVC pipes can be used at temperatures ranging from -20 ℃ to 70℃；

三、Impact resistance: The impact resistance at room temperature is more than 5 times that of CPVC;

四、Flame retardancy: extinguished immediately after ignition;

五、Corrosion and aging resistance: The product is acid and alkali resistant, UV resistant, and weather resistant. Its service life can reach 50 years outdoors and 70 years underground;

六、Lightweight: The product density is one-fifth that of steel pipes, making installation convenient;

七、Cost performance: More stable in price than polyolefin materials, better in performance than chlorinated polyvinyl chloride pipes and fiberglass, and more convenient in construction than steel pipes.
