That is, agricultural high-density polyethylene irrigation pipes, which are special pipes for agricultural water-saving irrigation and landscaping irrigation systems, and have the core advantages of weather resistance and anti-aging, strong flexibility, excellent hydraulic performance, and are suitable for sprinkler irrigation, drip irrigation, micro-irrigation and other irrigation modes
Excellent weather resistance and anti-aging performance
The pipe can be added with anti-ultraviolet stabilizer, and when used outdoors, the anti-aging life can reach more than 30 years, and it will not be embrittled or cracked due to direct sunlight, which is suitable for the open-air laying scene of farmland and gardens.
Good hydraulic performance, water and energy saving
The inner wall is smooth, the roughness coefficient is only n=0.009, the water flow resistance is much lower than that of concrete pipes and cast iron pipes, and the water transport distance is longer and the flow rate is larger under the same irrigation pressure, which can reduce the energy consumption of the pump and meet the requirements of water-saving irrigation.
Strong flexibility and adaptation to complex terrain
The elongation at break ≥ 400%, and it can be transported in coils and bundles (the length of a single coil with a small pipe diameter can reach 500m), which can adapt to the terrain undulations of farmland ridges and ditches and hilly slopes, without the need for a large number of elbow pipe fittings, and the construction efficiency is significantly improved.
Corrosion resistance, hygiene and environmental protection
It does not react with irrigation water and fertilizer solutions (such as urea and compound fertilizer dilutions), and will not precipitate harmful substances to pollute the soil and crops. It is resistant to soil acid and alkali corrosion when buried and lays, and does not require anti-corrosion treatment.
Lightweight, easy to construct, low maintenance cost
The density is only 1/8 of that of steel pipes, and it can be handled and laid manually without large equipment. After the hot melt or special pipe fittings are connected, the sealing is good, not easy to leak, and there is basically no need for maintenance in the later stage.
2. Main uses
HDPE irrigation pipes are widely used in various irrigation systems such as agriculture, gardens, and greenhouses, and the specific scenarios are as follows:
Water-saving irrigation system for farmland
Field irrigation main pipe/branch pipe: used for sprinkler irrigation and pipe irrigation system for field crops such as wheat, corn, cotton, etc., with a pipe diameter range of DN50~DN315 and an adaptive pressure of 0.4~1.0MPa, which can achieve long-distance water transmission;
Orchard / Vegetable Field Drip Irrigation / Micro Sprinkler Irrigation Branch Pipe: Small pipe diameter (dn20~dn50) HDPE pipe is used as a connecting pipe for drip irrigation belt and micro sprinkler head to accurately transport water and fertilizer mixture and improve water and fertilizer utilization.
Landscaping irrigation
The sprinkler irrigation system for urban parks, square green spaces, and street trees is commonly used in DN32~DN110, which can be buried in the ground or installed overhead, taking into account both beauty and practicality.
The golf course's fine irrigation pipe network uses its flexibility to adapt to the undulating terrain of the course and ensure an even water supply to the lawn.
Greenhouse irrigation
As the main pipe and branch pipe of drip irrigation and atomized irrigation in the greenhouse, the pipe diameter DN20~DN75 can be flexibly arranged between the crop rows, and the fertilizer spreader can realize integrated irrigation of water and fertilizer, which is suitable for the high temperature and high humidity environment in the greenhouse.
Municipal and industrial and mining green irrigation
The green irrigation system of industrial parks and residential communities, as well as the sprinkler irrigation pipe network of mine reclamation and slope greening, can meet the needs of outdoor harsh environments with weather resistance and corrosion resistance.
