GR Pipes

Usage And Advatages

  • GR is among the easiest to use in drip-irrigation systems in terms of installation, dismantling, and maintenance.
  • It is mostly used in the irrigation of vegetables in open fields and green houses.
  • It is very efficient in irrigating trees that are planted close to each other, such as banana trees.
  • It contains a cylindrical dripper that is attached to the inside wali of the pipe.
  • This pipe is available in two sizes: 16 mm (with 1.1 mm thickness) and 20 mm (with 1.2 mm thickness).
  • Ideal operating pressure for this pipe is 1 Bar.
  • It is available in different flow capacities : 2 L/H, 4 L/H, and 8 L/H.
  • The spacing between drippers starts from 20 cm and reaches up to 100 cm or more.
  • It can be produced in a way that allocates a number of drippers to every one tree (grouping).
  • Chemicals and fertilizers that may be added to the water do not affect the pipe.
  • It can be easily cleaned from calcium carbonate precipitation by adding some diluted acids.

Recommended Length for GR pipes according to spacing between drippers (in meters) GR 16mm pipes.

PC Pipes (In Line Pressure Compensating Dripper)

Usage And Advantages

  • The P.C. Pipe is the latest in drip-irrigation systems, wherein it contains a dripper with a regulator for pressure. This mechanism enables the system to deal with pressure inside the pipe ranging from 0.5 Bar up to 4.5 Bar, while maintaining the same designed flow and sufficient pressure within the irrigation network.
  • Available with 3.8 L/H capacity as well as 2.2 L/H and comes in 16 mm and 20 mm pipes.
  • P.C. pipes can be used for lengths of up to 200 m, subject to the availability of suitable pressure, thus helping realize:
    • Savings in main lines.
    • Easy ploughing of the soil after the removal of the irrigation network.
    • Maximum usage of the land (no erosion because of the main lines).
  • The consistency of the irrigation water enhances the consistency in the size and snape of fruits; thus reflecting positively on the marketability of these fruits.
  • Ideal for use in sloping terrain and hilly areas.
  • Ideal for agricultural research facilities because of its ability to provide consistent irrigation.

PE 100

HDPEOur polyethylene pipe has been approved internationally as suitable for use in portable water piping systems. High density pipes are known to be stiffer and less flexible; however, low density pipes are softer and more flexible. For these reasons, high density pipes are used for main and sub main lines, where as low density pipes are used for lateral lines. Such pipe material is purchased from major suppliers and have the following advantages:

  • Corrosion resistant and chemical resistant.
  • Microbiological attacks and impact resistant.
  • Weather resistant.
  • Non –contaminating, non-toxic.
  • Able to convey pressurized hot water.
  • Its ability to resist cracks at low temperature .
  • It contain 2.3% carbon, the best production againt UV.
