HDPE Pipe Applications:
1. Drinking water supply system
2. Nature Gas supply system
3. Food and chemical industry
4. Replacement of cement pipes and steel pipes
5. For Mine, argillaceous silt/mud transportation
6. Irrigation and garden green pipe networks and sewage treatment
HDPE Pipe Advantages:
1.Non-toxic, apply to drinking water supply widely.
2.Green Initiative , PE is a recycled material, environment friendly.
3.Corrosion resistance: PE belongs to inert materials, can resistance to various chemical media.
4.Long working life. Minimum 50 years life under normal conditions.
5.Low system cost, less maintenance costs, reduce the cost for the project.
6.Good flexibility, high resistance to impact. Resistance to earthquake and twisting.
7.Non-leakage, PE pipe be connected by Electric welding.
