PE100 grade water supply pipe
1、 Product Features
1. Corrosion resistance
The molecular structure stability of PE pipes is extremely high, with no electrochemical corrosion. Except for a few oxidants, they can withstand corrosion from various chemical media.
2. Good anti-corrosion performance
Among many pipeline materials, the corrosion index of PE pipes is relatively small. When transporting mineral sand slurry, its corrosion resistance is more than four times that of steel pipes.
3. Good flexibility and impact resistance
PE pipe is a high toughness pipe material with a fracture elongation of over 500%. It has excellent impact resistance and earthquake resistance, and has strong adaptability to uneven settlement of the pipe foundation.
4. Long service life
PE pipe has high molecular weight, good stability and anti-aging performance. Under normal operating temperature and pressure conditions, the service life of PE pipe can be guaranteed to be more than 50 years.
5. Good hygiene and environmental performance
PE pipes do not add metal stabilizers during the processing, and the material is non-toxic, without a scaling layer, and does not breed bacteria. It is a safe and hygienic pipeline material. PE material itself is recyclable and does not produce substances that have an impact on the environment.
6. Safe and reliable construction connection methods
PE pipes are mainly connected by hot melt or electric melt, essentially ensuring the integration of interface material, structure, and the pipe body itself, without the worry of water or gas leakage.
7. Lightweight, easy to handle and construct
Lightweight, with a specific gravity of only 1/8 of metal pipes, easy to handle and bend, simple and rapid welding process, low overall engineering cost, and significant economic benefits.
