Advantages:
1. Chemical stability: as lack of polarity in molecules, HDPE material has good performance in chemical stability despite of few oxidants, most of chemical medium cannot damage, corrosion-resistant and anti-stain, interior flow capacity not be reduced after long time usage, HDPE pipe is a kind of environment-friendly product
2. Formidable joint strength: mainly refer to thermal welding for example, few joints, no leak
3. Convenient installation: lightweight and easy 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: 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 adapt special defending or protecting, convenient to install in winter, in the mean time, pressure-resistant test can stand 2.5 times nominal pressure by water hammer
7. Corrosion-resistant: Germany lab ever proofs anti-corrosion of HDPE material is several times than copper
8. Longevity: more than 50 years under proper use
