Several types of irrigation pipes commonly used in agricultural irrigation!

Irrigation pipes are widely used in urban and rural indoor and outdoor water supply and drainage, rural water improvement, field irrigation, brine pipelines in the field of salt industry, water supply in aquaculture industry, mine ventilation, water supply and drainage engineering, landscaping projects and sprinkler irrigation equipment.

Irrigation methods for agriculture and animal husbandry can generally be divided into traditional surface irrigation, general sprinkler irrigation equipment and irrigation. Traditional pavement irrigation includes furrow irrigation, furrow irrigation, flood irrigation and infiltration irrigation, but this irrigation method usually consumes a large amount of water and has a relatively low water utilization capacity, which is a very unreasonable agricultural and animal husbandry irrigation method. Nowadays, with the improvement of people's awareness of green environmental protection, the irrigation method has already changed, and the birth of irrigation methods such as micro sprinkler belt and drip irrigation belt has gradually replaced the traditional way.

1. Micro spray tape

(1) The micro sprinkler belt is to send the water to the field through the water supply pipeline and sprinkler irrigation pipe under the working pressure, according to the drainage port in the micro sprinkler belt, under the influence of force and friction resistance, the actual effect of spraying like continuous drizzle. Sprinkler irrigation is a new type of irrigation machinery and equipment, also known as "sprinkler irrigation belt", "micro sprinkler belt", "sprinkler belt", "sprinkler pipe head", "porous structure plastic hose" and so on.

(2) Most of the drainage outlets of the micro sprinkler belt are classified by multi-head and short heads, arranged according to a certain distance and certain rules, such as: oblique five holes, oblique tees, horizontal three holes, upper and lower holes and no holes, etc., the drainage port generally adopts mechanical drilling, running holes and laser punching machines, with a diameter of 0.1~1.2mm, and a hollow shape.

(3) Main uses: vegetables and fruits, fungi, seedling bases, plantations, potted flowers, greenhouse planting crops.

2. Drip irrigation belt

(1) Drip irrigation belt is the use of plastic hose (drip irrigation pipe pilot) channel to send water to the roots of crops through the nozzle or drip irrigation pipe in the capillary with a diameter of about 10mm to carry out partial irrigation. It is a drip irrigation pipe or drip irrigation belt with a particularly small outlet nozzle, and the water is evenly and slowly dripped into the soil near the roots of the crops. The drip irrigation belt is divided into patch drip irrigation belt, built-in cylindrical drip irrigation pipe, air-sealed drip irrigation belt, and dark blue rail drip irrigation belt.

(2) In the process of capillary manufacturing, the drip irrigation pipe that has been manufactured in advance should be embedded in the drip irrigation belt, such as patch drip irrigation tape and embedded cylindrical drip irrigation pipe.

(3) Under the premise of producing and manufacturing thin pipes, the thick-walled drip irrigation belt should be hot-melted on one side or in the middle of the pipe to relieve the seepage and outlet of the pressure flow channel, such as the air-sealed drip irrigation belt and the blue rail drip irrigation belt.

(4) Main uses:

  a. It is used for the planting of greenhouses and greenhouse crops, reducing diseases, saving chemical fertilizers and pesticides, and improving efficiency.

  b. It can be used for plantation irrigation, which can effectively improve efficiency, improve fruit quality, and effectively manage the growth and development of wild grasses.

  c. It is suitable for a variety of crops such as cotton wool, Chinese herbal medicines, melons, field fruits, etc., and improves the range of mechanized planting.

  d. The drip irrigation belt can be bent and paved around the wall, which is easy to operate.

3. PE irrigation pipe

PE pipe is also known as polyethylene water supply pipe, and the middle of the pipeline system software is connected by electric hot melt, and the joint strength is higher than the strength of the pipe itself.

(1) Characteristics of PE irrigation pipes for agricultural machinery

(1) Reliable connection: The middle of the pipeline system software is connected by electric hot melt, and the strength of the joint is higher than the strength of the pipeline itself.

(2) Good ultra-low temperature impact resistance: during winter construction, due to the good impact resistance of raw materials, there will be no brittle cracking of pipelines.

(3) Strong resistance to stress cracking: It has low notch sensitivity, strong cutting strength and excellent scratch resistance, and the resistance to environmental stress cracking is also very outstanding.

(4) Good solvent corrosion resistance: the pipeline can resist the erosion of various organic chemical media, and the compounds in the soil layer will not cause any degradation to the pipeline.

(5) Anti-aging, sturdy and durable.

(6) Good wear resistance: The comparative test of the wear resistance of the pipeline and the steel pipe shows that the wear resistance of the pipeline is 4 times that of the steel pipe.

(7) Good flexibility: the softness of the pipeline makes it very easy to bend, and the obstruction can be bypassed by changing the direction of the pipeline in the project.

(8) Low water flow resistance. Easy to ship.

(9) a variety of a new engineering construction mode: in addition to the traditional foundation pit excavation mode construction, can also adopt a variety of a new trenchless technology such as pipe jacking construction, fixed item punching, lining, cracking pipe and other ways of construction.

4. PVC irrigation pipe:

(1) PVC pipe has excellent acid resistance, alkali resistance and corrosion resistance, and is quite useful for chemical use; The boundary layer of PVC pipe is smooth and clean, the flow resistance is small, and its roughness coefficient is only 0.009, which is lower than that of other pipe fittings, and the pipe diameter can be variable under the same platform flow. The water pressure resistance, compressive strength, impact strength and so on of PVC pipe are very high, and it is mainly suitable for pipeline engineering projects in the situation. The price is low and the use is wide

(2) PVC irrigation pipe can well follow the growth process of grain crops to modernize the development of irrigation. The amount of water required for irrigation can be selected according to the actual seedling conditions of the food crops and their soils.

(3) The most unique thing about PVC irrigation pipe is that it can achieve an accurate water injection method of supplying electricity and fertilizer to the roots of grain crops according to the characteristics of recent weather. This can reduce the trouble of manual work.

(4) PVC irrigation pipe is able to transport more reasonable irrigation water demand according to the needs of crop growth and development, which can ensure that more moderate and appropriate irrigation of grain crops can be guaranteed, and lay the foundation for improving crop production

(5) Irrigation pipes are widely used in large and small projects such as urban and rural indoor and outdoor water supply and drainage, rural water improvement, field irrigation, brine pipelines in the salt industry, water supply in the aquaculture industry, mine ventilation, water supply and drainage projects, and sprinkler irrigation equipment for landscaping projects.
