What a dripline is
A dripline, also called an in-line drip pipe, is a light polyethylene pipe with cylindrical emitters fitted inside its wall at set intervals. Water moves along the pipe and comes out slowly at each emitter. Because the emitters are already inside, there is no need to punch the pipe and fit emitters one by one.
A dripline differs from drip tape in its wall and service life. Drip tape is flat and thin-walled and is used mostly for seasonal crops, while a dripline is a round pipe with a sturdier wall, made for orchards and permanent crops where the system must last several seasons.
Sizes and what to state when ordering
In our rows the dripline comes in two diameters, 16 and 20 mm, in coils. Our catalogue lists the product with several variables: diameter, wall thickness, emitter spacing, emitter flow and whether the emitters are pressure-compensating (PC) or not.
An irrigation designer sets these by tree type, planting distance, soil and row length. In your enquiry give the diameter, wall, emitter spacing, flow, PC or non-PC and total length so a suitable coil is offered. The dripline is connected to the sub-main with 16 and 20 mm lateral fittings and a start connector.
Looking after a dripline through the season
To prevent dripper clogging, filter the incoming water with a suitable filter and open the line ends every so often to flush out sediment. At the end of the season, if the lines must be taken up, coil them without kinks.
When fertigating, run plain water through the network for a few minutes after injecting so no fertiliser stays in the drippers.

Cylindrical Dripline — FAQ
What is the difference between dripline and drip tape?
Dripline is a round pipe with a sturdier wall and built-in emitters for permanent crops; drip tape is flat and thin-walled for seasonal crops.
Which diameters are supplied?
16 and 20 mm, in coils.
How is emitter spacing chosen?
By crop, planting distance and soil; an irrigation designer is best placed to set it.
How is it connected to the main pipe?
With a start connector or off-take valve on the PE sub-main.
