Irrigation pipes are widely utilized in urban and rural indoor and outdoor water supply, rural water improvement projects, agricultural field irrigation, brine pipeline transport in saline industries, water transport in aquaculture, mine ventilation, water supply and drainage, and garden greenery spraying.
Agricultural irrigation methods generally fall into traditional surface irrigation, conventional sprinkler irrigation, and micro-irrigation. Traditional surface irrigation includes furrow irrigation, ditch irrigation, flood irrigation, and sprinkler irrigation, but these methods often consume large amounts of water with low efficiency, making them less rational for agricultural irrigation. Nowadays, with the increase in energy-saving and environmental awareness, there has been a revolutionary change in irrigation methods. The emergence of micro-spray tapes, drip tapes, and other irrigation methods has gradually replaced traditional methods. Now let’s introduce several commonly used irrigation pipes in agriculture.
- Micro-spray Tape
Micro-spray tape is a new type of micro-irrigation device that delivers water to fields through water supply pipes and micro-spray tapes. Through the water outlets on the micro-spray tapes, fine rain-like spraying is achieved under the action of gravity and air resistance. The water outlets of micro-spray tapes are often arranged in multi-space groups at certain distances and patterns, such as oblique five-hole, oblique three-way, horizontal three-hole, left and right holes, and no holes. The water outlets are generally mechanically drilled, punched, or laser-drilled with diameters ranging from 0.1 to 1.2mm, with a circular shape.
Applications: Suitable for vegetable fields, mushroom cultivation, nurseries, orchards, flowers, and greenhouse crops.
- Drip Tape
Drip tape utilizes plastic pipes (drip irrigation pipes) to deliver water through tiny holes or drippers with a diameter of about 10mm to the roots of crops for localized irrigation. It drips water uniformly and slowly into the soil near the plant roots. Drip tapes are divided into patch-type drip tapes, embedded cylindrical drip irrigation pipes, labyrinth drip tapes, and blue track drip tapes.
Applications:
- Used for planting in greenhouses and greenhouses to reduce pests and diseases, save fertilizers and pesticides, and improve economic benefits.
- Suitable for orchard irrigation to effectively increase yields, improve fruit quality, and control weed growth.
- Applicable to various field crops such as cotton, Chinese herbs, watermelons, and field vegetables, improving the degree of mechanized planting.
- Drip tapes can be laid around ridges and bent for easy operation.
- PE Irrigation Pipe
PE pipes, also known as polyethylene pipes, are connected between pipeline systems using electrothermal fusion, with joint strength higher than that of the pipe itself.
Characteristics of Agricultural PE Irrigation Pipes:
- Reliable connection: Pipeline systems are connected using electrothermal fusion, with joint strength higher than that of the pipeline itself.
- Good low-temperature impact resistance: During winter construction, the material’s impact resistance prevents pipe brittleness.
- Excellent stress cracking resistance: It has low notch sensitivity, high shear strength, and excellent scratch resistance, with outstanding resistance to environmental stress cracking.
- Good chemical corrosion resistance: Pipes can withstand corrosion from various chemical substances in the soil without degradation.
- Long service life due to good aging resistance.
- Excellent wear resistance: Comparative tests with steel pipes show that the wear resistance of pipes is four times that of steel pipes.
- Good flexibility: Pipes are easy to bend, allowing for changes in pipeline direction to bypass obstacles.
- Low water flow resistance and easy transportation.
Applications:
- Widely used in urban and rural water supply and drainage projects.
- Suitable for field irrigation in various irrigation areas.
- PVC Irrigation Pipe:
PVC pipes have excellent acid, alkali, and corrosion resistance, making them suitable for chemical industry applications. The smooth inner surface of PVC pipes reduces fluid resistance, with a roughness coefficient of only 0.009, lower than other pipe materials, allowing for smaller pipe diameters at the same flow rate. PVC pipes have high resistance to water pressure, external pressure, and impact, suitable for piping projects under various conditions. They are affordable and widely used.
PVC irrigation pipes can accurately supply water and fertilizer to crop roots based on current weather conditions, reducing manual labor. These pipes can adjust irrigation water volume according to crop growth needs, ensuring timely and adequate irrigation to improve crop yields.
PVC irrigation pipes are widely used in various agricultural and landscaping projects, providing an efficient and reliable solution for water transport and distribution.
