HDPE Double Wall Corrugated PipeDetailed Product DescriptionSmooth inner surface of the pipe insures large input flow with small fluid friction. The pipe is not easy to block. HDPE double wall corrugated pipe used for drainage, sewage. Economical and environmental, easy to instal. 1. Characteristics1) Smooth inner surface of the pipe insures large input flow with small fluid friction. The pipe is not easy to block.2) Connected easily with rubber rings, easy to install.3) Light weight makes pipe transportation more convenient.4) Flexible connection to insure the pipe operate well after unevenly movement of the earth, not easy to leak. 5) Chemically stable, corrosion-resistant, non-toxic, non-polluting, an environmentally friendly products.6) Economical compared other traditional pipes.7) Life span can be 50 years buried underground on normal conditions Advantages

 

 1.      Chemical stability:

 

As lack of polarity in the molecules, the HDPE material has good performance in chemical stability. In spite of few oxidants, most of the chemical medium can not damage. Corrosion resistant and anti stains. The interior flow capacity not be reduced after long time usage. HDPE pipe is a kind of environmental product.

 

 2.      Formidable joint strength:

 

Mainly refer to the thermal welding. For eg. Few joints, no leak.

 

 3.      Convenient installation:

 

Light weight and ease of installation. Can reduce installation cost, especially in bad environment.

 

 4.      Higher flow capacity:

 

Smooth interior walls result in lower pressure loss and higher volume.

 

 5.      Better wrap and bend ability:

 

The vertical allowable bending benefits the construction on fluctuant earth surface.

 

 6.      Low temperature preservation:

 

Anti-embrittlement temperature reaches -70oC,and under common low temperature (-30 oC), no need to adopt special defending or protecting. Convenient to install in winter.

 

   In the mean time, the pressure resistant test can stand 2.5 times nominal pressure by water hammer.

 

 7.      Corrosion resistant:

 

Germany lab ever proofs anti-corrosion of the HDPE material is several times than that of copper.
