| 20120080114 | DUCT LEAKAGE CONTROL - The invention provides an apparatus and methods for duct leakage control wherein a sealing element is introduced into the duct and is automatically drawn or otherwise guided to the locality of a leak, the element being caused, by reason of a pressure differential attributable to the leak, to move into and stem or seal the leak. The sealing element may comprise a plurality of individual members of differing buoyancy, each capable of being carried along at a predetermined level in the duct by the flow of fluid therein. The sealing element may carry a tagging device which can be used to assist in locating the leakage site. | 04-05-2012 |
| 20110295527 | METHOD FOR ESTIMATING THE LOCATION OF A LEAK IN A PIPELINE - A method for estimating a location of a leak (x) in a pipe ( | 12-01-2011 |
| 20110187056 | DUCT ASSESSMENT AND LEAK SEALING METHOD FOR DUCTS TRANSPORTING GAS - The present invention relates to a method of assessing the condition of a duct along which a gas is flowing. The method comprises producing one or more sensor carrying elements, wherein the elements are formed to have selected parameters; introducing the sensor carrying elements into the flowing gas; and selecting the parameters of the sensor carrying elements such that the elements are transported along the duct by saltation. The present invention also relates to a method of reducing leakage through a leak in the duct. In this respect, the method comprises producing sealing elements, wherein the sealing elements are formed to have selected parameters; introducing a plurality of the sealing elements into the flowing gas; and selecting the parameters of the sealing elements such that the elements are transported along the duct by saltation and such that, at the locality of the leak, at least one of said sealing elements is captured by a pressure differential associated with the leak and is thereby drawn to and held in position at the leak for stemming or sealing it. | 08-04-2011 |
| 20080196481 | Deriving Information About Leaks in Pipes - A method and system for deriving fluid leak information are described. A plurality of sealing elements are introduced into the pipeline at a location upstream of the leak, and at least some of the sealing elements are drawn towards the leak to cause a sealing event which reduces fluid seepage. A pressure change caused by the sealing event is detected, and associated time data is used to derive information about the leak. In one embodiment, leak location information is derived. In an alternative embodiment, pressure transient information is used to derive leak size information. | 08-21-2008 |
