COVERLINE - Sprinkler Irrigation (Total Aerial Coverage)


Types of available couplings - COVERLINE® System

The COVERLINE® System is a sprinkler irrigation system combining high density polyethylene pipes with aluminium couplings, which are available in Ø50, Ø63 and Ø75 with different types of couplings.

The patented system COVERLINE® for sprinkler irrigation developed by SALEPLAS, S.L. combines high density polyethylene pipes with aluminium couplings in order to obtain a total aerial coverage irrigation system that guarantees a highly homogeneous watering. The pipes are manufactured in a chemical resistant and shockproof material, which results in a longer service life of the installation

The COVERLINE® System consists of PE-80 polyethylene pipes with a nominal pressure of 6 bar in Ø50, Ø63 and Ø75 mm. The connections can be made with three different kinds of couplings: hook, half turn or lever. The system is complemented by a great variety of accessories to adapt to any type of installation design.



  • Easy handling thanks to the quick coupling and low weight.
  • The pipes are flexible, which allows an easy assembly, great resistance to impacts and farm working without risk of damaging the pipes.
  • The watering can be adapted according to the irrigation time of each sector.
  • The couplings are compatible with most of the system available in the market.
  • It can be adapted to crop rotation and rescue irrigation.
  • It facilitates the growing of the plants in crusted soils.
  • It allows an efficient removal of salts.


  • Cereal
  • Onion
  • Horticultural crops
  • Beetroot
  • Cotton
  • Potato
  • Tobacco 


  • It can be adapted to big plots as well as small or irregular ones.
  • We get a better uniformity coefficient (UC) using two nozzles instead of one. For that reason, we recommend installing sprinklers with 2 nozzles in order to obtain a homogeneous watering.
  • Due to the extra cost and increasing production of small drops, the working pressures higher that 4 bar should be avoided.
  • The systems should be designed for small rainfall (6-8 mm/h) in order to avoid waterlogging of the soil. In this case, the irrigation time must be increased.
  • A proper maintenance of all the elements of the installation should be made (obstructed or broken sprinklers, pressure control, filtration systems, etc.)
  • The sprinkler lines should be installed permanently or only for the season. They can be moved to other plots according to the planned crop rotation.
  • The sprinkler lines must be oriented according to the crop rows in order to facilitate the farming work.
  • We must avoid installing sprinkler lines on an up gradient.
  • The difference of pressure of the sprinkler lines must be kept 20% below of the average pressure.
  • Pressure regulators may be needed for the lines installed on irregular topography.
  • Maximum number of sprinkler in Ø50 sprinkler line: 11 sprinklers between 1.000-1.200 l/h.
  • Maximum number of sprinkler in Ø63 sprinkler line: 20 sprinklers between 1.000-1.200 l/h.
  • It is not advisable to work when the winds blows hard, as the water is not distributed properly and does not reach the ground.
