HDPE WATER PIPE
The polyethylene water supply pipe is a new product formed from
extruding, taking the high quality polyethylene resin as main
material, adding necessary assistant such as anti-oxidant
ultraviolet absorber and so on. The polyethylene water supply pipe
has application history of forty years abroad. It is perfect choice
in many pipelines by the approving of practice. It can be widely
used in many kinds of pipeline projects with the working pressure
of 0.32MPa~1.6MPa and the working temperature of -20℃~40℃, such as
municipal water supply, drainage, petrochemical industry, mine,
irrigation of agricultural land, contamination drainage, mortar
transportation, landfill of refuse and so on.
Advantages of HDPE Pipes
1. Excellent physical characteristics
The inward high quality polyethylene has good rigidity and
intensity, and also has good suppleness and anti-creep, and the hot
melting performance is good, which is convenient for the mounting
of the plastic pipelines.
2. Corrosion resistant, long lifespan
In the coastal areas, the ground water lever is higher, the ground
humidity is great, the seamless steel pipes must be used to prevent
corrosion, and the lifespan of the steel pipes is only 30 years.
While the HDPE pipes can proof many chemical mediators which cause
the corrosion without needing the corrosion proof treatment. In
addition, it will not improve the alga, bacteria or epiphyte
growing. The lifespan can reach up to 50 years under the normal
3. Good toughness and suppleness
HDPE pipe is high toughness tubing, the breaking extension exceeds
500%. It has very strong adaptability to the dropping with uneven
base and dislocation, good shock resistance. It has been proved by
practice all over the world that the HDPE pipes are the pipelines
with excellent shock resistance. In addition, the suppleness of the
HDPE pipes can make them coiled up easily at a small diameter,
which decrease a lot of connection pipe fittings. In construction,
the allowable bending radius of the pipes can bypass obstacles,
which can decrease the construction difficulties.
4. Great negotiability and economical
The inner wall of the HDPE pipes is very smooth. The equivalent
absolute rough radio of the inner wall is 1/20 of the steel. The
price of the HDPE pipes under the same pipe diameter, length and
pressure is about 30% of the steel pipes.
5. Convenient for connection, easy to construct
The HDPE pipe is very light. It is convenient for transportation
and easy to weld. The weld-throat section is few.
6. Good sealing performance
The HDPE pipe adopts the hot melting connection which guarantees
the identity of the joint material structure and pipe body and
realizes the integration of the joints and the tubing. The tensile
and burst strength are both higher than the pipe body, which
effectively resist the ring stress from the inner pressure.
7. Good stress resistant performance
The HDPE pipe has low gap sensitivity, high shear strength,
excellent scar resistant ability and outstanding environment
8. Low temperature shock resistance
The brittle temperature of the polyethylene is very low which can
be used in the temperature range between -20℃~ 40℃.
9. Good abrasion resistance
It can be shown in the abrasion resistance performance test of the
polyethylene pipes and steel pipes. The abrasion resistance of the
HDPE pipe is 4 times of the steel pipe.
10. Low flow resistance
The inner wall of HDPE pipe is very smooth. The smooth wall and
non-adherence performance can guarantee the flow capacity of the
HDPE pipes. At the same time, this will decrease the pressure loss
and energy consumption of the water flow.
1. Town Water Supply
With integrative advantages of safe, health and continent for
construction, the HDPE pipeline has been the perfect tubing for the
town water supply.
2. Food, Chemical Industry Area
With the unique chemical corrosion performance, the HDPE pipe can
be used in the transportation and emission of many acid, alkali and
salt solutions. The working life is long, the cost and maintenance
discharge is low.
3. Argillaceous Silt, Mud Transportation
The abrasion resistance of the PE pipelines is four times of steel
pipes, so it can be used to transport the argillaceous silt,
pulverized fuel ash of the power plant, mud accumulated in the
4. Replace the Cement Pipes, Cast Iron Pipes and Steel Pipes
To reform the cement pipes, cast iron pipes and so on laying
previously. Without digging in large area, the PE pipes can be
inserted into the old pipes for replacing at low construction cost
and short construction time. It is suitable for the reformation of
the old city especially.
5. Garden Green Pipe Network
The garden green needs lots of the water transportation pipelines,
as the cost of the PE pipelines is very low, it is worthy to be
