Netafim UniRam Heavywall PC Dripline, 18 in Spacing
Long rows, slopes and hard water all test a dripline, and a pressure-compensating heavywall line handles all three. This coil is Netafim item 14201-000037, model 08UR18.6-18, holding 1,000 ft of 18 mm UniRam. The tube has a 0.620 in inside diameter and a 45 mil wall. Drippers sit every 18 in and each delivers 0.6 GPH, or 2.3 L/h. They compensate from 7 to 58 psi, so flow stays the same at the head and the tail of the run. With a flow exponent of zero inside that range, dripper output holds within the plus or minus 7 percent allowed by ISO 9261. A wide filtration area at the dripper inlet and a TurboNet labyrinth with large water passages resist clogging. The silicone diaphragm flushes debris continuously during every cycle. An anti-siphon mechanism stops dirt from being drawn back into the drippers at shutdown, which suits buried lines. A physical root barrier protects the dripper without relying on chemicals.
Planning Rows at 18 Inch Spacing
At this spacing, each 100 ft of lateral carries about 67 drippers and applies roughly 40 GPH. A full coil therefore draws close to 6.7 GPM when the whole length runs together. Close spacing builds a continuous wetted strip under row crops and dense plantings. Filter to 80 mesh, or 200 micron, which is the level matched to this dripper flow. Where sand exceeds 2 ppm, place a hydrocyclone ahead of the main filter. The line works on the surface or buried, and in greenhouse, nursery, field and landscape plantings. Join runs with the matching twist-lock coupling and close them with a figure 8 line end in the same size. High UV resistance and tolerance of standard fertilizers suit long seasons under fertigation. Coverage runs 7 years for defects and 10 years for environmental stress cracking. Flush the laterals at startup and at regular intervals through the season.
