Abstract
A drip irrigation conduit comprising first and second elongated tubes. The tubes have an outer wall of sheet material defining the outer periphery of the tubes. A common wall of sheet material extends from one region of the outer wall to another region of the outer wall to separate the interiors of the tubes. A portion of the common wall overlaps a portion of the outer wall, and these overlapping portions have confronting surfaces. At least regions of the confronting surfaces are spaced apart to define a transfer passage leading from the first tube to the second tube. Discharge orifices lead from the second tube to the exterior of the outer wall.
