HDPE SDR11 Drip Irrigation Watering Hose

HDPE WATER PIPE

Overview

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 condition.

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 resistance stress.

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.

Application Area

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 river way.

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 improved widely.
