HDPE double wall corrugated pipe shall be double wall corrugated pipe PE, HDPE double wall corrugated pipe for wide temperature range (+60 ℃ -20 ℃), products with high ring stiffness, strength, quality of light, noise damping, higher UV stability, long life and good bending, pressure, impact resistance, high strength, corrosion resistance, cold resistant and many other advantages, PE double wall corrugated pipe ends are sealed rubber ring embedded in the trough, with good waterproof seal, can be laid in sections with poor geological, construction of fast, widely used in communications, telecommunications, cable laying. The practice has proved to meet the same strength and stiffness requirements, the use of double-wall corrugated pipe PE pipe than ordinary plastic material savings 30% to 50%, and easy transportation and installation, reducing labor intensity of construction personnel, but also reduced the project The total investment is concrete pipe, cast iron pipe ideal replacement product.
