• 1. Reliable connection

  The polyethylene pipeline system is connected by electric melting method, and the strength of the joint is higher than that of the pipeline body.

• 2. Good low-temperature impact resistance

  The low-temperature brittleness temperature of polyethylene is extremely low, and it can be safely used within the temperature range of -40 · 60 ℃. During winter construction, due to the good impact resistance of the materials, there will be no occurrence of pipe brittleness.

• 3. Good chemical corrosion resistance

  HDPE irrigation pipes have low notch sensitivity, high shear strength, excellent scratch resistance, and outstanding resistance to environmental stress cracking.

• 4. Good chemical corrosion resistance

  HDPE pipes can withstand corrosion from various chemical media, and the chemicals present in the soil will not cause any degradation of the pipes.

• 5. Aging resistance and long service life

  Polyethylene pipes containing 2-2.5% uniformly distributed carbon black can be stored outdoors or used for 50 years without being damaged by ultraviolet radiation.

• 6. Good wear resistance

  The comparative experiment of wear resistance between HDPE pipes and steel pipes shows that the wear resistance of HDPE pipes is four times that of steel pipes. In the field of mud transportation, compared with steel pipes, HDPE pipes have better wear resistance, which means that HDPE pipes have a longer service life and better economy.

• 7. Good flexibility

  The flexibility of HDPE pipes makes them easy to bend, and in engineering, they can bypass obstacles by changing the direction of the pipe. In many cases, the flexibility of the pipe can reduce the amount of pipe fittings and lower installation costs.

• 8. Low water flow resistance

  HDPE pipes have a smooth inner surface with a Manning's coefficient of 0.009.

• 9. Convenient transportation

  HDPE pipes are lighter than concrete pipes, galvanized pipes, and steel pipes. They are easy to handle and install, with lower labor and equipment requirements, which means that the installation cost of the project is greatly reduced.

1. Municipal landscaping, greening, irrigation

2. Rural farmland water conservancy irrigation

3. Irrigation of seedlings in rural orchards

4. Rural aquaculture water supply

The inner and outer surfaces of HDPE irrigation pipes are smooth, flat, without cracks, dents, discoloration lines, and other surface defects that affect the performance of the pipes. The pipe should not contain visible impurities, and the end face of the pipe should be cut flat and perpendicular to the axis. PE irrigation pipes used on the ground and buried should not be translucent. The total length of PE irrigation pipe straight pipes is generally 6, 9, 10, and 12 meters, and small-diameter coil pipes are generally 100 and 200 meters, which can also be agreed upon by the supply and demand parties. The color is generally black, and the connection method is hot melt welding.
