Abstract: A pipe having a wall formed from a cross-laminated film, and a method of making such a pipe. The film is formed of first and second layers having respective first and second orientation directions, wherein an angle between each of the first and second orientation directions and a projection of a longitudinal axis of the pipe on the wall is selected to enhance the resistance of the pipe to circumferential and/or longitudinal strain due to internal fluid pressure. The angle between each of the first and second orientation directions and a projection of the axis on the wall may be substantially equal to the neutral bias angle. In some cases, the angle between each of the first and second orientation directions and the projection of the axis on the wall may be substantially equal to 59° ± 2°.

Abstract: An irrigation pipe comprising at least one layer is provided. The layer has a maximum longitudinal tensile strength in the longitudinal direction of the pipe and a maximum tensile hoop strength along the circumference of the pipe. The value of the maximum longitudinal tensile strength is substantially less than the value of the maximum tensile hoop strength.

Abstract: There is provided an insert to be sealingly mounted into a plug hole of a pipe having a sealing area surrounding the plug hole. The insert comprises an internal unit (20) and a fastener (30). The internal unit and the fastener have corresponding cooperating sealing portions and mounting portions. The sealing portion of the internal unit is formed with a flange (22) adapted to be forced into the plug hole. The flange and the sealing portion of the fastener have corresponding sealing surfaces. These surfaces are adapted to sealingly clamp therebetween the sealing area of the pipe, when the insert is mounted into the plug hole. One of the sealing surfaces being in the form of a sealing edge (23) and the other being in the form of a conical surface (32). When the fastener is mounted onto the internal unit, the sealing portions of the internal unit and the fastener form therebetween a chamber. The chamber is in fluid communication with the outside environment, allowing atmospheric pressure within the chamber.

Abstract: An irrigation pipe (58) formed from a sheet that is rolled into a tube about a longitudinal axis of the sheet. The pipe has a watertight layer and a fabric layer (30). The fabric layer comprises a first fiber arrangement including first main fibres (34) having a first orientation and a second fiber arrangement including second main fibers (36) having a second orientation. The first and second orientations are transverse relative to each other and to the longitudinal axis when viewed in the sheet before it is rolled.

Abstract: An irrigation pipe connector (16) has a core (18) that is adapted to connect to an irrigation element (40) and a wing (20) that is attachable to a wall of a pipe (10). The wing (20) is provided with resiliency to allow the connector (16) to deform in response to changing fluid pressures in the pipe (10). In addition, the wing (20) may be provided with a thin segment in order to reduce potential damage during welding of the wing to the wall of the pipe (10).
