Pressure pipes, essential elements for the conduction of water through “The Water Way”
When talking about irrigated agriculture and its corresponding installations, a fundamental part of them is the network of pipes, as these are responsible for carrying the water from the point of supply (well, pond, water intake…) to the crops, passing through the irrigation head.
These pipes, in charge of transporting water for irrigation, have a circular section, since this geometric shape is the most efficient when it comes to conducting the water. In addition, the adaptation and capacity to support loads in a buried circular pipe will be better than with one of a different geometric shape.
What factors should we take into account when selecting the type of pipe for our irrigation installation?
The pipes recommended for an irrigation installation are those made of Polyethylene (PE), a thermoplastic material that can change its shape depending on the temperature and pressure it is subjected to.
Pipes made of virgin PE instead of recycled, are of better quality, as they provide a guarantee of healthiness that those made of recycled material do not, so they can be used for transporting drinking water for human consumption.
There are several types of PE pipes, among which the “Medium Density” (P40) and “High Density” (P100) stand out.
“Did you know that a polyethylene pipe can have a useful life of between 40 and 50 years?
Medium-density pipes are softer and more flexible, allowing them to curve and adapt better to the irregularities of the terrain. Its flexibility not only makes it easier to install, as it can make steeper bends, but also makes it more tolerant of crushing without collapsing. In addition, they are easier to transport as they are less heavy.
High-density pipes are much more rigid than the previous ones, so they adapt less well to the irregularities of the terrain. Therefore, they are usually used as the main pipes of the irrigation system, from which the secondary pipes come out, which are usually made up of lower-density pipes, which are the ones that “cross” the crop fields, adapting better to the orography of the terrain.
Advantages of using Polyethylene pipes:
- They are very resistant to chemical products, so they are very appropriate for agricultural, livestock and industrial use.
- They have a long useful life.
- They are very easy to handle thanks to their flexibility, which allows them to be transported comfortably.
- They have great flexibility, which will allow them to adapt to a wide range of needs, facilitating their installation.
- They are a great thermal insulator, which allows them to withstand extreme temperatures. In times of very low temperatures it will prevent the water from freezing. However, if it did, thanks to its high flexibility quality, the pipe would not burst, returning to its initial state when the thaw occurs.
