Round drip irrigation pipes are produced with diameters of 16 and 20 mm and wall thicknesses between 0.9 and 1.0 mm. Compared to flat drip pipes, round drip pipes, which have a thicker wall, are preferred for shorter distance irrigation. The coil lengths are 400 m, and they can drip water from 2 liters to 4 liters per hour. The dripper spacing can vary from 20 cm to 100 cm.
