HDPE double wall corrugated pipe

HDPE density polyethylene double wall corrugated pipe is a new type of light-weighed pipes, with smooth inner surface, ladder-shaped corrugated surface and an empty layer between double surfaces. With its unique wall structure design, such pipe has advantages of strong ring stiffness, light weight, high pressure resistance, good toughness, anticorrosion, anti-abrasion, convenient and low cost installation and long service life,etc.It is widely used in municipal transforming projects.constructions,agricultural and industrial drainage, agricultural water-saving irrigation, wastewater processing industry,etc.and is the best substitute of traditional concrete pipes, cast iron pipes and other material pipes.

According to different ring stiffness grades,HDPE double wall corrugated pipe falls into S1(ring stiffness≥4KN/m2)and S2(ring stiffness≥8KN/m2).Generally speaking, S1 will be selected when it’s buried with dynamic load or in 0.7~5m underground or while S2 selected when it’s buried without dynamic load or too shallow and too deep. Specifications are as below (nominal inner diameter):200mm, 225mm, 300mm, 400mm, 500mm, 600mm, 700mm ,800mm and 1000mm.

Product characteristics

l  Unique product structure, thus high pressure resistance

l  Smooth inner surface, thus large flowing amount

l  Convenient pipe connection, perfect sealing ,anticorrosion, no leakage, no scaling, no secondary pollution, the ideal environment-friendly pipes.

l  Good flexibility and adjustability to uneven sinking of soil.

l  Long service: Its service life can reach 50 years when buried.

l  Light weight: Convenient installation brings lower construction costs and less time.

l  Anti-abrasion property is 3~5 times higher than common steel pipes at a flowing rate of 15 feet per second.
