HDPE Large Diameter Double Wall Corrugated Pipe
HDPE large diameter double wall corrugated pipe is a new variety of lighting pipeline. The inner wall is small, and the outer wall is a trapezium corrugated pattern. Between the two walls is a hollow sandwich. These pipes have a number of advantages, including high intensity, light weight, sound insulation, shock absorption, better ultraviolet ray absorption and more. These large diameter HDPE pipes are widely used for construction in municipal engineering, industrial transformation, water-saving irrigation and drainage in the agricultural industry, and waste water treatment. Our large diameter HDPE double walled corrugated pipes are excellent replacements for traditional cement pipes, iron pipes and other tubing materials.
The hoop stiffness of HDPE large diameter double-wall corrugated pipe is divided into SN4 and SN8, nominal (internal/external diameter) DN/ID: 200mm, 225mm, 300mm, 400mm, 500mm, 600mm, 700mm, 800mm.
Unique structure, strong resistance to pressure
The inside wall is smooth, making large discharge amounts convenient
The pipes are easy to connect, have a high tensile strength, excellent sealing and corrosion resistant performance. The HDPE pipe is an ideal environmental protection pipe.
Excellent bending property, making it applicable for the uneven settlement of earth
Service life of more than 50 years
These pipes are lightweight, making them convenient for construction and reducing construction costs and the construction period.
The abrasive resistance is 3 to 5 times higher than normal iron pipes under the speed of 15 feet/m.
