HDPE double-wall corrugated pipe for drainage
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 example, few joints, no leak
3. Convenient installation: lightweight 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 -70°C, and under common low temperature (-30°C), 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
8. Longevity: more than 50 years under proper use
