摘要:
An irrigation pipe with holes is provided. The pipe is, at least in the area of each hole, multilayered. At least top and bottom layers of the pipe are made of a water-repellant material, and an inner layer of the pipe is made of a porous material. The hole is defined by a cut surface of the pipe wall. The cut surface comprises a seal, which covers at least the inner layer. Each layer may be bonded to adjacent layers.
