HDPE Gas Pipe Applications:

1.PE gas pipe is suitable for gas transportation on condition that working temperature is among -20°c~40°c

2.Long-term maximum working pressure is not more than 0.7MPa.

3.Polyethylene Gas Pipe is suitable for Gas distribution network both for domestic & industrial consumption.

HDPE Gas Pipe Advantages:

1.Non-toxic, health:PE pipe material non-toxic, tasteless, through the strict health monitoring,

it belongs to green building materials, never scaling, which can effectively improve the water quality.

2.Corrosion resistance:PE belongs to inert materials, can resistance to various chemical media.

3.No leakage:PE pipe is connected by electric melting, its interface strength higher than tube itself .

4.High toughness:fracture extension rate of PE pipe,commonly more than 500%.As to the uneven settlement of the base, its adaptive ability is very strong, good aseismic performance.

5.Excellent resistance to quickly crack propagation (RCP) ability.

6.Excellent flexible and resistance to scratches ability.

7.Good wear resistance, low wall friction coefficient, small flow resistance, excellent conveying ability.

8.Can use a variety of trench less ways, great convenient for construction and installation.

9.Low system cost, less maintenance costs, can dramatically reduce the cost for the project.

10.Long service life: dark bury PE pipe normal uses more than five years.11.PE material can be reused, complete with the concept of efficient environmental protection which our

state advocates .

11. Appearance: Yellow stripes
