China is a large agricultural country, and there are not a few irrigation water used in farmland. With the improvement of people's awareness of energy conservation, the irrigation mode has undergone earth shaking changes. At present, the most common irrigation mode is pipeline irrigation.
Advantages of Pipeline Irrigation
- Water saving. The pipeline water conveyance system can reduce leakage and evaporation loss and improve the utilization rate of water resources.
- Fast water delivery, time-saving and labor-saving. Pipeline irrigation is carried out under certain pressure, which is generally faster than that of Soil Canal. Timely water supply can save irrigation labor.
- Timely irrigation to help agricultural production. Pipeline irrigation can not only improve the field irrigation conditions, but also reduce water loss and shorten the irrigation cycle, so as to meet the water demand for crop growth, increase yield and increase income.
- Reduce land use efficiency. It is convenient for irrigation and occupies a large amount of land. Due to the shortage of land resources in China, the per capita cultivated land is less than 1.5 mu. Pipeline irrigation will save some land use.
- Pipeline irrigation has many advantages, among which the irrigation pipe made of PE is widely recognized by the market because of its excellent performance.
Characteristics of Agricultural PE Irrigation Pipe
- Reliable connection: the pipeline systems are connected by electrothermal fusion, and the strength of the joint is higher than that of the pipeline body.
- Good impact resistance at low temperature: during construction in winter, due to the good impact resistance of the material, pipe embrittlement will not occur.
- Good stress cracking resistance: it has low notch sensitivity, high shear strength and excellent scratch resistance. It also has outstanding environmental stress cracking resistance.
- Good chemical corrosion resistance: the pipeline can resist the corrosion of a variety of chemical media, and the chemicals in the soil will not cause any degradation to the pipeline.
- Aging resistance, good wear resistance and long service life.
- Good flexibility: the flexibility of the pipeline makes it easy to bend. In farmland construction, obstacles can be bypassed by changing the direction of the pipeline.
- Small flow resistance and convenient handling.
- A variety of new construction methods: in addition to the traditional excavation method, a variety of new non excavation technologies can also be used, such as pipe jacking, directional drilling, lining, pipe cracking and so on.
In addition to PE pipes, PVC in plastic materials can also be used as irrigation pipes for field irrigation in various types of irrigation areas.
Characteristics of Agricultural PVC Irrigation Pipe
PVC pipe has excellent acid, alkali and corrosion resistance, which is very suitable for the purpose of chemical industry; The wall of PVC pipe is smooth and the fluid resistance is small. Under the same flow, the pipe diameter can be reduced. The water pressure resistance, external pressure resistance and impact resistance of PVC pipe are very high, which is suitable for piping engineering under various conditions.
PVC irrigation pipe follows the growth process of crops to realize modern irrigation. The irrigation water consumption can be selected according to the specific conditions of crops and soil.
PVC irrigation pipe can realize the irrigation technique of supplying water and fertilizer directly to the roots of crops according to the characteristics of the current weather, which can reduce manual operation.
PVC irrigation pipe can deliver more reasonable irrigation water according to the growth needs of crops, so as to ensure more timely and appropriate irrigation of crops and lay a solid foundation for improving the yield of crops.
Irrigation pipes are widely used in urban and rural indoor and outdoor water supply, rural water improvement, farmland irrigation, brine transmission pipelines in Salinization industry, water transmission in aquaculture, mine ventilation, water supply and drainage, landscaping sprinkler irrigation and other large and small projects.

How to Choose Agricultural Irrigation Pipeline?
PE pipe is the most durable for farmland irrigation pipe. Farmland irrigation pipe must bear certain pressure. Generally, PE resin with large molecular weight and good mechanical properties should be selected. PE pipe is high-density polyethylene pipe.
PE pipe for agricultural irrigation mainly refers to LDPE pipe, which belongs to low-density polyethylene pipe. It is made of the best polyethylene resin extruded and contains less than 2% carbon black. After strict quality screening, the LDPE pipe has excellent aging resistance and frost resistance. It prolongs the service life and brings many convenience to agricultural irrigation. Therefore, it has also been loved and supported by many farmers.
Application and Advantages of PE Pipe in Agriculture
Because the LDPE tube itself has excellent aging resistance and frost resistance, its service life is guaranteed. In addition, the inner wall of LDPE pipe is smooth, which reduces the loss of water head; What is more worth mentioning is that it is flexible and easy to coil, which can adapt to topographic changes and make the construction and installation more convenient. Therefore, LDPE pipe is mainly used for head adjustment of agricultural irrigation system, installation and intubation of dripper and micro nozzle, drainage and irrigation system, hydraulic engineering, chemical industry, plant cooling, etc.
