Best PVC Pipe for Underground Drainage in Pakistan
Underground drip irrigation is an irrigation method that uses a pipeline system to deliver water and releases irrigation water into the soil in the root zone of crops through an irrigator buried in the ground on capillary tubes for absorption and utilization by crops. Compared with surface drip irrigation technology, subsurface drip irrigation has the advantages of reducing ineffective surface evaporation, improving crop root zone soil conditions, facilitating field management operations, and preventing capillary aging, but there are also disadvantages such as high technical requirements, large investment, and easy clogging.

Compared with surface drip irrigation technology, subsurface drip irrigation has the advantages of reducing ineffective surface evaporation, improving crop root zone soil conditions, facilitating field management operations, and preventing capillary aging. Try to find best upvc pipes in Pakistan.


In recent years, as the shortage of water resources and the shortage of agricultural water have become increasingly prominent, subsurface drip irrigation technology has received more and more attention, and its equipment and technical level have also become higher and higher.

Underground drip irrigation technology is also getting more and more attention, and its equipment and technical level are getting higher and higher. Dripper is a key component of subsurface drip irrigation. Internationally, countries such as Israel, South Korea, the United States and Australia have been in the leading position in research in this field. The development and application of subsurface drip irrigation technology in China began in the early 1980s, mainly for fruit tree crops. Field test results show that this technology has obvious effects of water saving and production increase. PVC underground drainage pipe is also widely used in Pakistan. Well, you can find best pvc pipe for underground drainage in Haili pipe.

There are still many problems in subsurface drip irrigation both technically and economically problems, such as the high cost of drippers buried underground, easy to block, strict technical parameters, and installation difficulty, once blocked, it is not easy to repair, etc., but this technology is applied to the production of greenhouse vegetables

It also has obvious advantages, such as saving water, increasing production, reducing indoor temperature, and inhibiting soil degradation, etc.

Therefore, in response to China's current greenhouse vegetable production needs, the original underground dripping system (best pvc pipe for underground drainage) should be continuously improved. Irrigation systems(pvc underground drainage pipe) and the development of simple and practical subsurface drip irrigation technology are of great significance.

Best PVC Pipe for Underground Drainage


1) The influence of different water supply pressures on the irrigation uniformity of the PVC pipe underground drip irrigation system

During irrigation, the irrigation water enters the drip irrigation pipe from the water delivery branch pipe and flows out from the water outlet hole into the soil; during this process, due to the influence of the friction of the pipe wall and the flow reduction, the water flow energy in the pipe decreases along the flow direction of the water body, causing the water to flow out of the water outlet hole. The amount of drip irrigation gradually decreases, resulting in uneven irrigation at the head and tail of the drip irrigation pipe, and the difference in soil moisture content in the corresponding parts is obvious. Under the condition that the drip irrigation pipes have the same diameter and certain materials, the most common way to solve this problem is to increase the water supply pressure during irrigation. Within a certain pressure range, as the water supply pressure increases, the proportion of water flow pressure (kinetic energy) loss caused by pipe(pvc underground drainage pipe) wall friction and outlet water outlet in the flow process to the water supply pressure (kinetic energy) decreases, which can make the drip irrigation pipe head end and tail end outlet hole The difference in water yield becomes smaller accordingly, so that the uniformity of irrigation is relatively improved.

2) The effect of different irrigation volumes on the uniformity of PVC pipe (pvc underground drainage pipe) irrigation

In the case of the same water supply pressure during irrigation, the uniformity of irrigation is also related to the amount of water at one time, because the amount of water at one time determines the moisture content of the soil near the water outlet, which in turn affects the water outlet speed of each water outlet. , and is also closely related to the movement process of soil moisture after irrigation. As the irrigation process proceeds, the soil moisture content around the outlet hole of the drip irrigation pipe gradually increases, causing the water outlet speed of the water outlet hole to decrease, resulting in a smaller difference in water flow pressure between the head end and the tail end of the drip irrigation pipe, and the water outlet speed of the water outlet hole tends to be consistent. Watering uniformity is improved.


Underground drip irrigation of PVC pipes can be summarized as follows:

1) The price of the pvc underground drainage pipe is low, the market supply is sufficient, and the technology of making and processing the drip irrigation pipe is simple.

According to the price of pvc underground drainage pipe sold in the market at that time and the processing fee, it is about 17,350 yuan/hm2 (among them, the cost is 12,350 yuan/hm2, and the processing fee is 5,000 yuan/hm2). The annual cost will be lower if the number of years is calculated; while the investment of ordinary underground seepage irrigation pipes is about 27,500 yuan/bm2 at the current price (of which, the cost is 22,500 yuan/hm2, and the processing fee is 5,000 yuan/hm2). 2) pvc underground drainage pipes are easy to bury and easy to meet the straight design requirements. 3) The water outlet hole is not easy to be blocked, and the irrigation quality is easy to be guaranteed. 4) The operation cost is low, energy saving, especially suitable for application in greenhouse vegetable production in northern China, easy to be accepted by farmers, and convenient for large-scale promotion.
