Material for the irrigation system in the selection of the main consideration is the material is subjected to mechanical stress, extreme temperatures, solar radiation, as well as its ability to chemical exposure may suffer. Mechanical stress may be due to internal conditions, such as water pressure, water acidity and alkalinity, water hammer and vacuum. Member may be made of an external force such as a ground load, thermal expansion and contraction, mechanical impact against the component. There can be a variety of combinations of metal, composites, plastics, ceramics, and elastomeric components for irrigation systems of. Not only should the material be able to withstand the mechanical and environmental stresses may occur, but they should be to each other to prevent internal corrosion or galvanic effect compatible. In the main consideration is the component selection pressure levels, wide temperature range, chemical affinity, and cost.

Polyvinyl chloride (PVC) pipe is under development in the chemical synthesis of the substrate and the results are computer-controlled manufacturing. It is extruded into a continuous seamless length with strong, chemical resistant, low friction losses, and is light weight, easy to operate. Type and grade refers to the ability to design stress pressure hydraulic tube. Type I, I class, is the most common micro-irrigation systems. There are two types I and II and Class I and II available.
