Netafim FlexNet Flexible Pipe, 3 in With 36 in Outlets
Rows planted on 3 ft centers call for a header with a takeoff at the head of every bed. This coil, Netafim item 43003-006042 and model 05FX03PIPE50-36, places an outlet every 36 in. Every outlet is an integral welded connector with a 1/2 in female thread. A tee or elbow start connector threads straight in, and Netafim fittings need no Teflon tape or glue. The pipe is 3 in nominal, with a 3.1 in bore and a 3.14 in outside diameter. Wall thickness is 0.030 in, and maximum recommended working pressure is 29 psi. The body is 100% recyclable polypropylene, resistant to UV and to chemicals. Charged with water it holds its length with zero axial elongation, so outlets stay lined up with the beds. Drained, it lies flat on the ground and tolerates foot traffic. Each 328 ft coil measures 5.6 in high by 31 in across and weighs about 46 lb.
Laying Out a Header With 36 Inch Outlet Spacing
Cut a shallow ditch across the bed ends first, so the pipe rests on soil and never bridges the gaps between beds. Load the coil with its arrows pointing the way the pipe will unroll. Unroll it with the colored stripe facing the ground and the outlets facing up. Keep the coil label, since it carries the traceability data for warranty purposes. On a windy site, fill the line right away or hold it down with a small soil mound every 2 m, clear of the outlets. Pronged poles driven beside the pipe also hold it in place. Curves need a radius of at least 16.5 ft, and a sharp turn calls for an elbow fitting instead of a fold. Never bend the pipe while it is under pressure. With 5/8 in thinwall laterals at 92% uniformity on level ground, a 1 psi friction budget allows 228 ft of header at 1.46 GPM per lateral and 162 ft at 2.50 GPM. Raising the budget to 2 psi stretches those runs to 291 ft and 204 ft.
