HDPE corrugated pipes

Product Detail:

HDPE double wall corrugated pipe is formed by welding and extruding the corrugated outer wall and smooth inner wall of high-density polyethylene at the same time. It has the characteristics of good corrosion resistance, high insulation, strong low temperature resistance, good sealing performance, and no leakage. It is lightweight, not easy to damage, and easy to install. It is one of the alternatives to concrete pipes and cast iron pipes.

Product Features

·Strong resistance to external pressure

The outer wall has a circular corrugated structure, greatly enhancing the circular stiffness of the pipe and thus increasing its resistance to soil loads. HDPE double wall corrugated pipes have significant advantages in this performance compared to other pipes.

·Low engineering cost

Under equal load conditions, HDPE double wall corrugated pipes only require thinner pipe walls to meet the requirements, saving 40-60% compared to steel pipes; Compared with cement pipes, the overall cost is basically the same; Compared with similar HDPE hollow winding pipes, it can also save 20-40%.

·Convenient construction

Lightweight, with a tube weight of only 0.94-0.96g/cm, and a long length (with few joints), making it easy to transport and connect; Low requirements for pipe trenches and foundations, easy connection and fast construction; The advantages of double wall corrugated pipe buried drainage pipes are more obvious in crowded urban areas and geologically harsh areas (such as high groundwater levels and soft foundations).

·Low friction coefficient, high flow rate

The inner wall is smooth with a roughness K value not exceeding 0.01mm, and the molecular surface of HDPE material does not carry positive or negative charges. Impurities with charges in water will not adhere to the pipe wall to form scale, so the flow rate is high. It has good sealing performance, no leakage, and can effectively control the pollution of groundwater resources.

·Good low temperature resistance and impact resistance

The normal working temperature of HDPE double wall corrugated pipe is between -40 ° C and 60 ° C, and it can also be constructed normally in extremely cold temperatures of minus 30 ° C. Currently, HDPE pipes are one of the few pipes that do not crack when frozen. The impact strength of HDPE is one of the best among plastic pipes (PE, PVC, PP, ABS, PB, etc.).

·Stable chemical properties

Its chemical molecules are non-polar and have excellent chemical stability. Except for a few strong oxidants, most chemical media do not have a destructive effect on it. It does not breed bacteria, does not scale, and its circulation area will not decrease with increasing operating time.

·Superior physical performance

It has good flexibility, good dynamic fracture toughness KD value, good seismic resistance, and can adapt to uneven settlement of the foundation. It is currently one of the pipeline materials with excellent seismic performance.
