Irrigation Pipes

A network of pipes supplying water to drip irrigation and sprinkler irrigation consists of the following elements:

  • Primary Pipe.
  • Secondary Pipe.
  • Tertiary Pipe.
  • Transmitter Porta Pipe.

The diameter of the pipes depends on the flow that has to be supplied, so the transmitter porta pipes will have a smaller diameter and primary pies will be much larger.

This scheme responds to the design of the most common networks that can be found on a farm, but does not have to be reproduced as such in a farm, as it depends on the surface to irrigate and network design.

Thus we can find:

  • Small farms with a primary pipe on which you install the Transmitter Porta Pipes
  • Large farms that require a level pipe (quaternary pipes) to which splice directly the Transmitter Porta Pipe.

Irrigation Pipes Materials:

Usual materials in irrigation pipes are:

Polyvinyl chloride (PVC):

Commonly used in primary and secondary networks, it can also be used as tertiary pipe. They are manufactured with two types of joints, gluing and gasket.

The advantage is that it is tougher than PE to the stresses caused by the water passing through the pipes, but turns out to be a brittle material that supports bad shock. It is usually buried to prevent accidental breakage and the effect of ultraviolet radiation on this material.

Low density polyethylene (LDPE):

It is used for mounting the tertiary network and portaemisores.

They are more flexible and less fragile than PVC, so they are used for plant sections are outdoors.

High density polyethylene (HDPE):

They are stiffer and harder than LDPE, with greater resistance to extreme temperatures and chemical agents tubes.

Aluminum:

Its use is limited to sprinkler irrigation facilities.
