  • Patent number: 11320084
    Abstract: Methods and systems for installation of a liner inside a conduit (e.g., water pipe) to transport a fluid (e.g., potable water) to rehabilitate the conduit, in which the liner can be installed, and thus the conduit can be rehabilitated, more efficiently, including, for example, by further reducing an extent of digging that may have to be done, by testing more readily (e.g., pressure-testing for watertightness or other fluid-tightness once installed), and/or by adapting to a cross-sectional size of the conduit. Also, the liner may be thinner, interact better (e.g., less) with the fluid flowing through the conduit, and/or be otherwise designed to enhance its use and performance.

  • Patent number: 11204125
    Abstract: An expandable pipe for restoring a damaged pipe is provided. The expandable pipe includes a liner formed of thermoplastic polyurethane, and grout material applied to the exterior surface of the liner. The exterior surface includes a plurality of flared tips and grooves, and each groove is located between adjacent flared tips. The grout material is disposed on the flared tips and in the grooves of the liner. The method used to restore the damaged pipe includes clamping the liner with the grout material on a puller-sealer fixture having a U-shaped cross-section to prevent debris from entering the interior of the liner, and pulling the puller-sealer fixture and liner through the damaged pipe. The grout material expands in volume upon exposure to moisture, ultra violet radiation, heat, and/or ultrasonics, and fills cracks or other imperfections and voids along the interior surface of the conduit, caused by corrosion, erosion, or other circumstances.

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: 9261221
    Abstract: The present invention provides a liner assembly for repairing the wall of a pipe that includes a transmitter or transmitters capable of transmitting information, such as identification information and physical characteristics of the area around the transmitter. Embedded in the liner is a transmitter, which includes a radio-frequency identification and at least one sensor. The RFID transmits identification information about the repaired wall, while the sensor provides physical characteristics of the environment in and around the pipe. Examples of physical characteristics may include temperature, pressure, flow, chemical reactions, velocity of the pipe, and the like. Additional transmitters may be used along the length of the pipe to determine characteristics at multiple locations, with each additional transmitter including the same or different sensors.

  • Patent number: 9248605
    Abstract: A liner tube for repairing existing pipes is provided. The liner tube is sufficiently flexible to lie substantially flat under its own weight thereby defining an upper portion and a lower portion. The liner tube includes an inner layer, an outer layer disposed around the inner layer, a first intermediate layer disposed between the inner layer and the outer layer, the first intermediate layer being wrapped around the inner layer to overlap itself and define a first overlap portion in the upper portion, and a second intermediate layer disposed between the first intermediate layer and the outer layer, the second intermediate layer being wrapped around the first intermediate layer to overlap itself and define a second overlap portion in the lower portion. The first and second intermediate layers include a porous material and the inner layer includes material substantially impermeable to liquids.

  • Patent number: 9074718
    Abstract: An apparatus and method of making a cured-in-place pipe repair to a lateral pipe having an area in need of repair. The method and apparatus use a liner assembly comprising a bladder tube and a liner tube. The liner tube comprises at least one layer of non-stretching material, which includes strands of non-stretching material oriented in the longitudinal direction of the liner tube. The strands allow radial stretching but ensure that the liner tube does not stretch longitudinally, which prevents the liner tube from stretching into a main pipe or past the area in need of repair during use. The liner tube may also comprise second and third layers of a resin impregnable material, such as felt, which surround the layer of non-stretching material such that the liner tube may be impregnated with a resinous material to repair a pipe having an area in need of repair.

  • Patent number: 9052053
    Abstract: A method for repairing a conduit using a tube-shaped liner comprising a single layer of resin-absorbent fabric having a polymeric coating attached to an outer wall of the tube and a reinforcing layer connected to an inner surface of the tube. The liner is impregnated with a resinous material capable of curing and hardening and inverted under pressure into the conduit to be repaired such that the reinforcing layer is pressed against the interior of the conduit. The resinous material is allowed to cure and harden, creating a lining to the conduit. The single layer of fabric may be a non-woven material, such as a felt. The conduit to be lined may be a sewer pipe, and the reinforcing material may be a woven scrim. The woven scrim may be capable of preventing longitudinal stretch of the liner tube while allowing radial stretch.

    Abstract: A segment for a rehabilitation pipe includes an inner surface plate having an inner circumferential surface, and side plates and end plates provided upright on a peripheral edge of the inner surface plate. The inner surface plate, the side plates, and the end plates are formed integrally from a plastic material. The segments are linked in a circumferential direction and in a pipe-length direction to install a segmental rehabilitation pipe inside an existing pipe. The end plates are provided with an insertion hole through which a linking member is inserted for linking the segments in the circumferential direction. Separately from the insertion hole, the end plates are further provided with an opening for passing therethrough a filler material injected into a space between the existing pipe and the rehabilitation pipe.

  • Publication number: 20150114507
    Abstract: A method and system for evaluating the interior surface and exterior wall conditions of a pipeline while also dynamically installing a repair coating in a pipeline, such as an underground water pipeline. The system is towed into the pipeline and drawn back therethrough. As the system is drawn back, one module in the system evaluates the surface condition of the interior of the pipe and another module evaluates the structural condition of the wall of the pipe. Based on the evaluation data obtained from the two modules an epoxy material is applied to the interior surface of the pipe using a spin cast machine that is drawn behind the two modules. Preferably, a layer of epoxy is applied to the interior surface of the host pipe to the appropriate thickness based on the pipe condition as determined by the two modules.
