A resin composition and method for installing a pipe liner that allows the liner to be fully wet out with a resin and activator and stored for a period of up to six months prior to installation and curing. A method of lining a pipe with a delayed curing resin composition is also provided that includes fully wetting out a liner with a blended two part epoxy composition such that the liner can be transported in a wet out fashion, placed in a pipe to be lined and repositioned as needed without concern for the resin composition to begin curing.

A method of installing a liner assembly for pipeline repair or reinforcement includes: pulling a prepared liner assembly into position in the pipeline, the liner assembly including a tubular liner wetted with a curable compound; introducing fluid into the inflatable bladder to bring the tubular liner into firm contact with an interior surface of the pipeline; flowing the fluid continuously through the bladder and discharging the fluid into the pipeline, while maintaining the liner assembly in an inflated condition; measuring a flow rate and a temperature of the fluid entering the bladder; calculating a time period sufficient for the tubular liner to cure based on: an amount of heat required for curing, based on dimensional information of the liner, and the measured flow rate and temperature of the fluid; and maintaining the liner assembly in an inflated condition for the time period sufficient for the tubular liner to cure.

Systems and methods for pipe lining systems and methods of use are described. Systems and methods may include a CIPP lateral liner that is inserted into a bladder forming a CIPP liner assembly that can be inserted into a pipe line for a pipe repair. CIPP liner assembly can include a membrane that produces superior results compared to the prior art. A backing ring may be used with these systems and methods.

The invention relates to: a device for curing resin-soaked lining sleeves with energy-rich radiation, comprising at least one radiation source for generating energy-rich radiation for curing a lining sleeve, at least one camera for capturing an image sequence of an environment of the device, and at least one input device, in particular provided separately from the device, wherein a capturing region and/or a display region of the camera is/can be adjusted by a user by means of the input device, and wherein an adjustment of the capturing region of the camera occurs via a movement of at least one part of the camera and/or occurs by means of an electronic image-processing device, which is designed and configured to adjust at least one camera parameter in accordance with an adjusted display region; and a use for a device of this type.

Robotic tools, methods, and systems for repairing pipes in-situ are described. A robotic tool includes a body with an annular, cylindrical configuration with a first end and a second end opposite the first end, the body having an inner surface defining an axis; a printing arm attached to the inner surface of the robotic body using a track, the printing arm circumferentially movable along the inner surface of the body; a printing head attached to the printing arm, the printing head movable radially along the printing arm and axially relative to the printing arm; and a plurality of legs positioned at axial intervals around the robotic body, each leg pivotably attached to the robotic body at either the first end or the second end of the body and pivotable between an open position and a closed position.

A tubular lining material for reinforcing pipelines, utilizable in a pipe-lining method wherein the tubular lining material, having a binder disposed on the inner surface thereof, is inserted into a pipeline and is allowed to advance within the pipeline as the tubular lining material is turned inside out under fluid pressure whereby the tubular lining material is applied to the inner surface of the pipeline with the binder being interposed between the pipeline and the tubular lining material, said tubular lining material including an outer layer of an impervious material and provided on the inside thereof with an inner reinforcing tubular jacket wherein the inner reinforcing tubular jacket includes at least two sheets of high tensile strength and/or high modulus fibers and wherein the sheets overlap at least two locations and wherein said overlap portions extend in the lengthwise direction of the inner tubular jacket.

A liner assembly and method for lining a damaged pipe junction between a main and lateral pipe is provided. The liner assembly includes a main liner member and a lateral liner tube. A collar disposed near the juncture between the main liner member and lateral liner tube is impregnated with a liquid hydrophobic or hydrophilic material capable of curing in a flexible or rigid state with the material expanding in the presence of water. The hydrophobic or hydrophilic material can also be applied without the use of the collar. When the liner assembly is pressed against the main and lateral pipes, a portion of the hydrophilic or hydrophobic material is forced into the damaged pipe junction.

The present invention relates to an impregnated fiber tube, also referred to as a liner, for internally lining conduits and pipes, a method of manufacturing the fiber tube, a method of rehabilitating pipes, and use of the fiber tube for rehabilitating pipe.

A resin composition and method for installing a pipe liner that allows the liner to be fully wet out with a resin and activator and stored for a period of up to six months prior to installation and curing. A method of lining a pipe with a delayed curing resin composition is also provided that includes fully wetting out a liner with a blended two part epoxy composition such that the liner can be transported in a wet out fashion, placed in a pipe to be lined and repositioned as needed without concern for the resin composition to begin curing.

A method for filling a gap with a filler material, enabling prevention of inflow of the filler material into an air removing tool through its opening before complete removal of air from the gap, and enabling uniform filling of the gap with the filler material. The gap is between an existing conduit and a lining material provided inside the existing conduit. The method includes: inserting an air removing tool into an air removing hole bored through the lining material, and bringing a leading end face of the air removing tool into contact with the inner circumferential surface of the existing conduit; and injecting the filler material into the gap while expelling air from the gap through a leading end of the air removing tool, the air removing tool including, at its leading end, an air removing portion through which air is discharged.
