Abstract: An irrigation pipe with a plurality of connector elements adapted for attachment of lateral branches thereto, where the connector elements are integrally fitted to the pipe's wall during the manufacture. Connector elements may be fitted open and be adapted for closing after manufacture if not intended for use, or may be fitted closed and be adapted for opening after manufacture to enable the attachment. A method of production of such irrigation pipe from a strip of flexible weldable or bondable material includes fitting integrally the connector elements to predetermined locations on the strip, with or without punching the strip; bending or twisting the strip so as to juxtapose or overlap lateral edges thereof; and welding or bonding integrally the edges so as to obtain a closed pipe section.

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: 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: 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.
