  • Patent number: 7681805
    Abstract: A dripper adapted to be bonded to interior of an irrigation pipe during manufacture and to be associated with an outlet opening in said pipe. The dripper comprises an outwardly facing surface adapted for the bonding, an outlet area associated with the surface, and at least one bulge near the outlet area. The bulge defines an outermost portion of the surface at least during manufacture of the pipe, and is adapted to form, when the dripper is bonded to the pipe, a raised outlet region in the pipe associated with the bulge. The bulge and outlet area are designed so as to form the raised outlet region suitable for at least a part of the outlet opening to be formed therein and be defined by the material of the pipe.

  • Patent number: 7644735
    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 and a fastener. 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 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 and the other being in the form of a conical surface. 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.

  • Patent number: 7588201
    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.

  • Publication number: 20090211661
    Abstract: An irrigation pipe connector has a core that is adapted to connect to an irrigation element and a wing that is attachable to a wall of a pipe. The wing is provided with resiliency to allow the connector to deform in response to changing fluid pressures in the pipe. In addition, the wing may be provided with a thin segment in order to reduce potential damage during welding of the wing to the wall of the pipe.
