  • Patent number: 11098836
    Abstract: The disclosed invention provides a device and method to detect leaks in pipelines and heal them instantly using twin ball technology. The device comprises two twin balls of novel construction inserted into the pipeline. The sensor ball receives acoustical data through internal sensors. Once the threshold of the sound level is surpassed, the smart ball will send a signal to the second flowing ball. The second ball will flow towards the leaking outlet and eject a healing fluid to close the leak and prevent further damage. The sensor ball will also alert the user to the size and location of the leak via Wi-Fi monitoring and text messaging. This twin balls technology could be used in pipelines of varying sizes and flow rates.

The opening is reversably enlarged during installation of the device to permit entrance of the pipe into partially encircled engagement by the body. Typically, three or more wheels are biased by the body into rolling engagement on the pipe at the installed position. Once installed, the device captures an end of the hoisting strap, and carries the strap end under the pipe as the device is rotated about the pipe centerline. The strap end can then be removed from the device to sling the pipe in a conventional lifting arrangement. The device can be removed from the pipe by pulling the device to again expand the opening.

  • Patent number: 10683959
    Abstract: A method and assembly for sealing an opening in a pipe wherein the opening is a damaged/cracked section in a length of pipe or the junction between a main pipe and a lateral pipe. The assembly includes a sealing member attached to a positioning tube such as preliner. The sealing member is combined with the preliner so that when the assembly is positioned in the main pipe, the sealing member corresponds with the opening. The sealing member is sized such that it extends along the main pipe on opposite sides of the opening. A mainline liner is installed within the preliner. In some embodiments, after the mainline liner cures and hardens, a cutter is used to cut an opening in the mainline liner, preliner, and sealing member to reinstate service to the lateral pipe. The sealing member remains in place around the periphery of the lateral pipe junction to act as a water stop at the opening.

  • Patent number: 10591102
    Abstract: A method and apparatus for repairing a pipe system including a main pipe extending between a first and second manhole and one or more lateral pipes extending from the main pipe is provided. Aspects of the invention include the use of a main liner member having a plurality of lateral liner tubes in fluid connection and extending from the main liner member. The main liner member is used to line a main pipe, while the multiple lateral liner tubes extend into separate lateral pipes extending in various orientations from the main pipe. This method and apparatus provides for a single assembly to be able to line multiple pipes, which reduces time and cost for pipe repair.

  • Patent number: 10571065
    Abstract: Techniques for refurbishing an existing host pipe, useful in deployments in confined spaces or providing limited access to the host pipe. In currently preferred embodiments, a plurality of cartridges each include (1) a liner pipe section, (2) at least one rod and (3) at least one centering ball, wherein each rod and centering ball is received inside its corresponding liner pipe section such that each rod is stabilized within its corresponding liner pipe section via contact between at least one centering ball and the liner pipe section. Once the first cartridge is inserted into the host pipe, a second cartridge is concatenated to the first by connection of their respective rods and liner pipe sections. The second cartridge is inserted into the host pipe, and so on. Upon completion, the rods and centering balls may be withdrawn from the concatenated string of liner pipe sections.

  • Patent number: 10557587
    Abstract: A tool with a rotatable guide head and a rotatable reamer head is pulled through old asbestos-containing pipe to break up the pipe. Liquid is supplied through a shaft between the guide head and reamer head so as to form a slurry mixture with the broken pipe. The slurry is removed through vertical bored relief holes. A drying compound is added to the slurry, which then hardens for easy disposal of the solidified waste material.

  • Patent number: 10495249
    Abstract: A method and means for repairing the junction of a main and lateral pipe are provided. A repair assembly includes a launcher device, a bladder assembly surrounding the launcher device, and a liner assembly surrounding the bladder assembly. The bladder assembly is frangibly connected to the launcher device to maintain the position of the bladder assembly relative to the launcher device during transport and positioning of the assembly. Likewise, the liner assembly, which includes main and lateral liner members, is frangibly connected to the bladder assembly. The frangible connections allow the position of the repair assembly to be maintained. The frangible connections can be broken, such as by inflation and/or tearing or pulling apart of the components of the repair assembly. Thus, the invention provides a way to mitigate the movement of components of the repair assembly during transport and positioning of the repair assembly.

  • Patent number: 10472931
    Abstract: A system and method for performing a flexible liner inversion out from a low-permeability borehole. A flexible liner may be installed by eversion down a subterranean borehole to selectively seal the borehole. Such a liner may be removed from the borehole by inverting it up the borehole. Water is added into the borehole beneath the lowest end of the liner, to permit or facilitate inversion of the liner. Water is allowed to flow from the interior of the liner to the borehole space beneath the liner, thereby raising the pressure in the unsealed borehole beneath the liner, and thereby allowing the liner to be further inverted upward. By allowing water to flow from the liner interior to a borehole volume beneath the liner, the need for a long vent or pumping tube is avoided.
