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 method of plugging at least one undesired opening in a fluid conduit can include introducing one or more plugging devices into the conduit, conveying the plugging devices by flow to the opening, and blocking the flow through the opening with the plugging devices. A system for plugging at least one undesired opening in a fluid conduit can include a deployment apparatus configured to introduce one or more plugging devices into the conduit, a sensor that measures a physical parameter indicative of leakage from the conduit, and a controller that activates an actuator of the deployment apparatus in response to receipt from the sensor of an indication of leakage from the conduit.

A device comprises: a container; a first fitting with a stationary piercing pin coupled to the container; and a second fitting coupled to the container, wherein the first fitting is configured for coupling to and piercing a sealed fluid filled canister and the second fitting is configured for coupling to a service port of the system such that a fluid can travel from the fluid filled canister through the device into the service port of the system, wherein the system comprises at least one of an air conditioning system or a refrigeration system.

The present invention relates to devices for repairing hoses of umbilicals. In this context, the present invention provides a device for repairing a hose (3) of an umbilical, comprising a tubular repair body (1) and a fusible element (2) adapted to obstruct the passage of fluid through the inside of the repair body (1), wherein the repair body (1) comprises an outside diameter that matches the internal diameter of the hose (3) to be repaired. In addition, the invention further provides a method for repairing a hose (3) of an umbilical comprising the steps of: blocking a first end (31) of a hose (3) of an umbilical; inserting a device for repairing a hose (3) of an umbilical into a second end (32) of the hose (3); injecting a polymer sealant into the second end (32) of the hose (3); using upstream pressure to move the repair device as far as the region of the leak, until the repair body (1) completely covers the opening/leak site (4); flushing the polymer sealant between the internal wall of the hose (3) and the external wall of the device as far as the opening/leak site (4) in the house (3); solidifying the polymer sealant, thereby attaching the tubular repair body (1) inside the hose (3); releasing the first end (31) of the hose (3) of the umbilical; and flushing the fusible element (2) through the inside of the hose (3).

A trenchless rehabilitation device for disconnects on large-diameter concrete drainage pipe and method thereof is provided; which includes: a pipe CCTV, a water blocking device, a lining repairing permanent structure, and a grouting device. The pipe CCTV is configured to determine the location of the pipe disconnection; the water blocking device is configured to form the working space; then the rubber seal lining short tube and multiple expanded round fixed steel plates are configured to form the inner repair permanent structure, and the grouting equipment is configured to insert the expanded round fixed steel plates. The grouting holes are configured to polymer grouting on the periphery of the pipe disconnection and the soil void. The trenchless repair process provided by the present invention can form a composite pipeline disjointed repair structure of inner repair permanent structure and polymer grouting material.

A pipe lining having at least two material layers, a first elastomeric layer spray applied directly to the inside of a pipe which acts as a hydrophobic, ductile membrane, and a second rigid layer is spray applied to the first layer prior to complete curing of the first layer. One or more additional layers may be applied to the second layer to provide additional abrasion, erosion or chemical resistance to the second layer. An intermediate reinforcing layer may be disposed between the first and second layers. The first layer cures into a closed cell elastomeric foam, such that stress and other forces are not passed from the pipe to the rigid second layer.
