    Abstract: A method for sealing a liquid leak in a pipe. The method may include wrapping a circumference of the pipe with a gasket material at a location of the leak to create an annular cavity between the gasket material and the pipe. The method may also include allowing the leaking liquid to exit from the annular cavity. The method may further include securing the gasket material to the pipe. The method may also include injecting an expandable grout into the annular cavity between the pipe and the gasket material. The method may further include allowing the grout to expand upon contact with the leaking liquid to create a seal around the leak. The method may also include adhering a reinforcement material to the gasket material and the pipe to reinforce the gasket material and the pipe at the location of the leak.

    Abstract: A scraper launcher includes a body having a rim and a trap door having a first surface and a second surface, where an interfacing portion of the second surface interfaces with an interfacing surface of the rim when the trap door is closed against the rim. A seal is provided between the interfacing portion of the trap door and the interfacing surface of the rim. The scraper launcher also includes a sealant injection system with sealant passages formed through the scraper launcher, fluidly communicating an exterior of the scraper launcher to an interior of the scraper launcher, and an injection fitting in communication with the sealant passages.

    Abstract: A clamp for repair of a pipe coupling, includes a clamp unit including a side wall with an inner surface, the inner surface having a curvature dimensioned to match an outer curvature of a pipe coupling to be repaired. A coupling on the clamp unit is constructed and arranged to couple a first portion of the clamp unit with a second portion of the clamp unit. The coupling, when secured, operates to induce a radially inward force on the inner surface of the clamp unit. A window is formed as an opening in the side wall of the clamp unit. The window is dimensioned to expose a flange of a pipe coupling to be repaired.

    Abstract: A subsea drying system (10) for drying a chamber (12) underwater has an upstream piping (24, 26, 28) for conveying a pressurized drying fluid from a source (18) to the chamber (12); and downstream piping (36, 38, 40) for expelling liquid displaced from the chamber (12) by the drying fluid in an open-loop dewatering mode. In a closed-loop dehumidifying mode, a recirculation path (54) between the downstream piping (36, 38, 40) and the upstream piping (24, 26, 28) conveys drying fluid exiting the chamber (12) back into the chamber (12) after passing through a dehumidifier (58). A valve system selectively closes and opens the re-circulation path to expel displaced liquid when that path is closed and to recirculate drying fluid from the chamber (12) through the dehumidifier (58) to the upstream piping (24, 26, 28) when that path is open.

    Abstract: A method and system for repairing a leak in a utility pipeline. The system includes a mold that is attached to the utility pipeline in proximity to a leak. The method further includes injecting an adhesive and/or a sealant into the mold and allowing the adhesive or sealant to cure to form a cast sealing the leak in the utility pipeline.

    Abstract: A polymer composite grouting method for blocking leaking and sand inrush of underground pipeline includes steps of: (1) determining a leaking and sand inrush position of an underground pipeline; (2) drilling a plurality of grouting holes in a ground surface; (3) placing two grouting pipes into each of the grouting holes, binding a film bag at a bottom of one of the grouting pipes; (4) injecting a polymer grouting material via one of the grouting pipes to form a polymer sand stabilizing body; (5) extruding water to accumulated in the pipeline; (6) installing a plurality of geotextile bags at the pipeline section displacement; (7) injecting the polymer material into the geotextile bags for blocking the leakage; and (8) filling the pumping area out of the pipeline. The present invention provides a practical technical measure to treat the leaking and sand inrush of the underground pipeline under complicated geological condition.
