Irrigation pipes are widely used in various large and small projects such as urban and rural indoor and outdoor water supply and drainage, rural water improvement, field irrigation, salt industry brine pipelines, aquaculture water supply, mine ventilation, water supply and drainage projects, and garden irrigation systems.
Agricultural and livestock irrigation methods can generally be divided into traditional surface irrigation, regular sprinkler irrigation, and micro-irrigation. Different irrigation methods correspond to different types of pipes and have varying utilization rates of water resources. Below, we will introduce the common types of irrigation pipes.
Micro spraying tape delivers water under pressure through water delivery pipes and micro spraying pipes to the fields. Through the water outlets on the micro spraying tape, under the action of gravity and air resistance, a fine rain-like spraying effect is formed. Most of the outlets use multi-head classified arrangements, based on certain distances and rules, such as oblique five holes, oblique three-way, horizontal three holes, upper and lower holes, and no holes. The outlets are generally mechanically drilled or laser-punched, with diameters ranging from 0.1-1.2mm, and the holes are perfectly round.
Micro spraying tape, also known as "sprinkler tape", "micro spraying belt", "sprinkling belt", "sprinkling pipe", "multi-hole hose", etc., is a new type of micro-irrigation device. It is mostly used for cultivating vegetables, mushrooms, nurseries, orchards, flowers, and greenhouse crops.
Drip irrigation tape uses plastic pipes (drip irrigation pipes) to deliver water through openings or drippers on small pipes with a diameter of about 10mm, directly to the roots of the crops for localized irrigation. It steadily and evenly drips water near the crop roots through very small outlet holes from drippers or drip irrigation tape. Drip irrigation tape comes in various types including patch type, in-layed cylindrical type, labyrinth type, and blue track type. These pipes can be laid in bends around ridges, making them convenient to operate.
Drip irrigation tape is widely used in greenhouses and plantations, such as for cotton and medicinal herbs, which are suitable for mechanized farming.
PE pipes, scientifically known as polyethylene pipes, connect the pipe system through electric hot melt methods. The joint strength is higher than the pipe body strength. They feature reliable connections, good low-temperature impact resistance, corrosion resistance, aging resistance, and low water flow resistance.
Besides, PE irrigation pipes are four times more wear-resistant than steel pipes and have excellent low-temperature impact resistance, making them not easily brittle in winter construction. Polyethylene can resist corrosion by various chemical media, and the compounds in the soil will not degrade the pipes.
PVC pipes have excellent acid, alkali, and corrosion resistance. They can deliver more reasonable irrigation water amounts according to the needs of crop growth, ensuring timely and appropriate irrigation and laying a solid foundation for improving crop yields. PVC irrigation pipes are widely used in urban and rural indoor and outdoor water supply, rural water improvement, farmland irrigation, brine pipelines in the salt industry, aquaculture water supply, mine ventilation, water supply and drainage, and garden irrigation systems.
