Advantage
1. Reliable connection: The polyethylene piping systems are
connected by electrothermal fusion, and the strength of the joint
is higher than that of the pipe body.
2. Good impact resistance at low temperature: The low temperature
embrittlement temperature of polyethylene is extremely low, and it
can be used safely in the temperature range of -60-60 °C. During
construction in winter, due to the good impact resistance of the
material, the pipe will not be brittle.
3. Good resistance to stress cracking: HDPE has low notch
sensitivity, high shear strength and excellent scratch resistance,
and its resistance to environmental stress cracking is also very
outstanding.
4. Good chemical corrosion resistance: HDPE pipes are resistant to
corrosion by a variety of chemical media, and the chemicals present
in the soil will not cause any degradation to the pipes.
Polyethylene is an electrical insulator, so it does not rot, rust
or electrochemically corrode; it also does not promote algal,
bacterial or fungal growth.
5. Anti-aging and long service life: Polyethylene pipes containing
2-2.5% evenly distributed carbon black can be stored or used
outdoors for 50 years without being damaged by ultraviolet
radiation.
6. Good wear resistance: the comparison test of wear resistance
between HDPE pipe and steel pipe shows that the wear resistance of
HDPE pipe is 4 times that of steel pipe. In the field of mud
transportation, HDPE pipes have better wear resistance than steel
pipes, which means that HDPE pipes have longer service life and
better economy.
7. Good flexibility: the flexibility of HDPE pipe makes it easy to
bend. In engineering, obstacles can be bypassed by changing the
direction of the pipe. In many cases, the flexibility of the pipe
can reduce the amount of pipe fittings and reduce the installation
cost.
8. Low flow resistance: HDPE pipe has a smooth inner surface, and
its Manning coefficient is 0.009. The smooth performance and non
adhesion characteristics ensure that HDPE pipes have higher
transportation capacity than traditional pipes, and also reduce the
pressure loss and water transmission energy consumption of the
pipeline.
9. Convenient handling: HDPE pipes are lighter than concrete pipes,
galvanized pipes and steel pipes. It is easy to handle and install,
and the lower labor and equipment requirements mean that the
installation cost of the project is greatly reduced.
10. A variety of new construction methods: HDPE pipeline has a
variety of construction technologies. In addition to the
traditional excavation method, it can also use a variety of new non
excavation technologies, such as pipe jacking, directional
drilling, lining, pipe cracking and so on. This is the only choice
for some places where excavation is not allowed. Therefore, HDPE
pipeline is widely used.
Details
Application
1) Urban water supply: PE pipe head has comprehensive advantages
such as safety, sanitation, and convenient construction, and has
become an ideal pipe for urban water supply.
2) Natural gas and gas transmission: PVC has become the best choice
for medium and low pressure natural gas transmission pipelines due
to a series of advantages such as reliable PE pipeline connection,
stable performance, easy construction and corrosion resistance.
3) Food chemical industry: PE pipes have unique corrosion
resistance and can be used for the transportation or discharge of
various salty and sour salts, resulting in long service life, low
cost and low maintenance cost.
4) Ore sand and mud transportation: PE pipe has a unique wear
resistance that is 4 times that of steel pipe. It can be widely
used to transport ore, fly ash of power plants, mud for river
dredging, etc.
5) Replacement of cement pipes, cast iron pipes and steel pipes:
For the replacement of old pipes with cement pipes, cast iron
pipes, etc. originally laid in the city, PE pipes can be directly
inserted into the old pipes for replacement without extensive
excavation, and the project cost is low , The construction time is
short, especially suitable for the pipeline re-selection in the old
city.
6) Landscaping pipe network: landscaping requires a large number of
water pipelines, and PE pipes have low cost and are worthy of
vigorous promotion.
