20090007968 | Pipe network, with a hierarchical structure, for supplying water or gas and/or for removing industrial water, process for detecting a leak in such a pipe network and process for determining, with the aid of a computer, the operating life theoretically remaining for a renewable power source for at least one flowmeter in such a pipe network - Summary: The invention concerns a pipe network ( | 01-08-2009 |
20090188569 | METHOD AND APPARATUS FOR PATCHING A WELL BY HYDROFORMING A TUBULAR METAL PATCH, AND A PATCH FOR THIS PURPOSE - A method of patching a well or a pipe by hydroforming a tubular metal patch. A tool provided with a pair of inflatable packers is inserted inside the patch. The pair of inflatable packers are axially spaced apart from each other by a distance that is substantially equal to the length of the patch. The tool is positioned inside the patch so that the packers are in register with the end portions of the patch. The assembly of the tool and the patch is axially inserted inside the well or the pipe, and positioned in register with the zone for patching. The packers are inflated to a high pressure, sufficient for radially expanding the end portions of the patch and pressing them in a leak-tight manner against the wall of the well or the pipe. The packers are subsequently deflated and the tool is withdrawn. The method is applicable to the oil industry. | 07-30-2009 |
20120024397 | SYSTEM AND METHOD FOR LEAKAGE CONTROL AND/OR TESTING OF PIPING AND DISCHARGE POINTS FOR NON-COMPRESSIBLE FLUIDS - System and method for controlling leakage and/or testing of pipe systems and discharge points for incompressible fluids, said system including one or more automatic valve arrangements ( | 02-02-2012 |
20130291952 | System and Method to Detect Accumulator Loss of Precharge - Methods and apparatus for detecting a leak in a gas precharged hydraulic accumulator having an initial gas charge entail activating a hydraulic pump to charge the gas precharged hydraulic accumulator and the hydraulic circuit associated with the gas precharged hydraulic accumulator when the hydraulic circuit and the hydraulic accumulator have a temperature that is substantially equivalent to an ambient temperature, e.g., on a cold start. The hydraulic pressure in the hydraulic circuit is monitored, and when a step in the hydraulic pressure is detected, various quantities are measured and used to determine a volumetric efficiency of the pump for use in later calculations of remaining gas amount. | 11-07-2013 |
20140109981 | MANAGEMENT TECHNIQUE FOR HYDRAULIC LINE LEAKS - A self-seeking plug for deployment in a hydraulic line with a leak therein. The plug is configured for circulation through the line and to a resting location adjacently below or past the location of the leak in the line. As a result, the location of the leak may be identified, for example with reference to a tether running between the resting location and the site of deployment. Thus, line repair may more readily ensue. Additionally, and/or alternatively, sealing repair may ensue by way of sealing element(s) outfitted on the plug. Such may or may not be accompanied by an exposable bypass channel through the plug for sake of full hydraulic restoration of the line. | 04-24-2014 |
20140305513 | METHOD AND APPARATUS FOR REAL TIME ENHANCING OF THE OPERATION OF A FLUID TRANSPORT PIPELINE - A real time method and dynamic logic-based system for enhancing the operation of a pipeline network is disclosed. The system and method perform monitoring of the operation of a pipeline network, generate alarms in response to differing levels of destabilized pipeline operations, manage the generation of alarms based upon known operating events and operating conditions, diagnose potential source of the detected destabilized events and manage the operation of the pipeline. | 10-16-2014 |
20140366954 | METHOD FOR REPAIRING AND IMPROVING STRUCTURAL INTEGRITY OF STORAGE TANKS - In some implementations of ignition-free welding in at least one fastener is attached to a container that resides within a hazardous environment. The fasteners are then used to secure a fill zone to the container. The chamber then receives a sealing material for the purpose of sealing a leak without having to remove the hazardous material. | 12-18-2014 |
20150107683 | METHOD OF REDUCING LEAKS FROM A PIPELINE - A method of reducing leakage from a pipeline includes the steps of: pumping fluid through a pipeline using at least one pump, the at least one pump comprising a reversible, positive displacement fluid pump; detecting a leak in the pipeline downstream of the pump; reversing the at least one pump to draw fluid out of a downstream section of the pipeline; and redirecting the fluid being drawn from the pipeline into a storage container. | 04-23-2015 |
