Introduction to HDPE Pipe:

HDPE pipe (High-density polyethylene pipe) is made from high density polyethylene as the main raw material, adding a small amount of antioxidants, Anti-UV absorbers and pigments.

Advantages of HDPE Pipe:

1.Nontoxic

2.Corrosion Resistant

3.Lower Installation Costs

4.Higher Flow Capacity

5.Longevity: more than 50 years under proper use

6.Recycled and Environment-friendly 

Properties of HDPE Pipe:

1.Specific Gravity, g/cm3, 20(C): 0.941-0.965
2.Longitudinal Reversion, % (110(C)): <=3
3.Oxidation Induction Time, min (200(C)): >=20
4.Extension Rate at Break. %: >=350
5.Hydraulic Pressure Test: 
1)20(C), Hoop Stress is 12.4 Mpa, 100h: No Failure.
2)80(C), Hoop Stress is 5.5Mpa, 165h: No Failure.
3)80(C), Hoop Stress is 5.0Mpa, 1000h: No Failure

Applications of HDPE Pipe:

1.City water pipe network system.
2.Urban and rural drinking water pipeline .
3.Chemical industry, chemical fiber, food, forestry, printing and dyeing, pharmaceutical. light industry, paper-making, metallurgy Industrial pipeline.
4.Agricultural irrigation pipe.
