Poly irrigation pipe

Poly irrigation pipe‌ is a plastic pipe with polyethylene as the main raw material, which has good corrosion resistance, wear resistance, and impact resistance. It is characterized by being lightweight, easy to install, low maintenance cost, and can be used in various harsh environments. The inner wall of the Poly irrigation pipe is smooth, the flow rate is large, it can be constructed across the road, and it has good impact resistance. It is an ideal pipe for agricultural irrigation.

Function

As the core component of the modern agricultural Pipe irrigation system, the importance of Poly irrigation pipe is self-evident. This pipe has become a powerful assistant for modern farmland irrigation with its excellent performance and wide application fields.

1. Poly irrigation pipe is based on its unique material, polyethylene (PE), which gives it excellent corrosion resistance. Whether facing the erosion of acidic and alkaline soils or being immersed in irrigation water containing various chemicals for a long time, PE irrigation pipe can maintain stable performance, no rust, no aging, and ensure the reliability of long-term use.

2. The flexibility of the PE irrigation pipe is also a highlight. Compared with traditional metal pipes, PE irrigation pipes can easily cope with various complex terrains and soil conditions. Whether it is rugged mountains or soft swamps, they can be easily laid, greatly reducing the difficulty and cost of construction.

3. The environmental performance of PE irrigation pipes is also commendable. As a recyclable material, PE irrigation pipes can be reused after simple treatment after reaching the end of their service life, reducing resource waste and environmental pollution. At the same time, less waste is generated during its production process, which meets the requirements of green production.

4. PE irrigation pipes also have excellent compressive resistance and wear resistance. Under certain pressure, PE irrigation pipes are not easy to break or deform; when impacted or rubbed by external objects, their surface can also maintain good integrity.

Connection mode

Poly irrigation pipe will be melted between 190 ° C and 240 ° C, using this feature to fully contact the two melted parts of the pipe (or pipe fitting), and maintain appropriate pressure, and the two can be firmly integrated after cooling. Therefore, the connection method of pe pipe is different from u-pvc pipe, usually using electric fusion connection and hot melt butt two ways, according to the size of the pipe can be divided into dn≤63, using injection molding hot melt socket connection; When dn≥75, hot melt butt connection or electric melt socket connection is used; When connecting with different materials, flange or thread connection is used.

Difference between PVC irrigation pipe and Poly irrigation pipe

In agricultural irrigation, polyethylene pipe (PE pipe) and polyvinyl chloride pipe (PVC pipe) are two common plastic pipe materials, which have their own advantages and are suitable for different application scenarios. Here are the main differences in agricultural irrigation:

 

1.‌ Corrosion and chemical resistance ‌

PVC pipe has excellent acid resistance, alkali resistance, and corrosion resistance, making it suitable for chemical industry applications. Its water pressure strength, external pressure strength, and impact strength are very high, suitable for all kinds of conditions of pipeline engineering ‌.

The main material of PE pipe is polyethylene, plus other reinforcement materials, which can obtain strong corrosion resistance, and its corrosion resistance even exceeds that of PVC pipe. PE pipes are more resistant to aging and UV rays, so they last longer in water-saving irrigation systems ‌.

2. Inner wall smoothness

The inner wall of PVC irrigation pipe is relatively smooth, with low fluid resistance and a roughness coefficient of only 0.009, which helps to reduce friction loss during transportation.

The inner wall of the PE pipe is smoother than that of the PVC pipe and has a lower friction coefficient, making it smoother when transporting irrigation water or even particles, reducing the risk of scaling and blockage.

3. Flexibility and adaptability:

PE pipe has better flexibility than PVC pipe, and can be freely laid, bent, and stretched in uneven terrain or various environments without damage. It is suitable for various types of uneven farmland, mountains, or greenhouses with high space utilization.

Although PVC pipes also have a certain degree of flexibility, PE pipes are more adaptable in applications that require large bends or deformations.

4. Cost: PVC pipes are relatively cheap, which makes them more competitive in cost-sensitive applications.

Although PE pipes may cost slightly more than PVC pipes, their longer service life and better performance make them more economical in the long run.
