摘要： A method for estimating a location of a leak (x) in a pipe (1). A liquid of a known density is fed into the pipe at a first inlet pressure (P1). When the liquid achieves a substantially steady flow rate, the flow rate passing into the pipeline is recorded. This step is repeated at a second, different, inlet pressure (P2). Using this data, an estimate of the leak location (x) and the area of the leak is calculated by simultaneously solving an expression which is based on relating the frictional energy losses of the liquid travelling through the pipeline (1) to the pressure in the pipeline at the leak (Pleak) and the flow rate of liquid from the leak.

摘要： The present invention relates to apparatus comprising one or more sealing elements (20) to be transported along a duct (24) by the flow of fluid therein at an internal pressure and to be drawn to a leak (22) by the pressure differential resulting from a reduced pressure associated with the locality of that leak. Each sealing element comprises a body formed from an elastic material to have one or more impermeable bubbles filled with gas so that the sealing element has a volume which varies resiliently according to the change in volume of the bubble (s) in response to externally applied pressure. The product of the volume of the bubble (s) and the pressure of the gas therein is selected to provide a sealing element having a transport volume at said internal pressure which is appropriate to enter a leak and which, in response to the reduced pressure associated with the locality of that leak, is capable of increasing in volume from said transport volume sufficiently to seal that leak.

摘要： A method is provided for reducing seepage through a leak (5) in a duct (1), the leak being defined in terms of its maximum dimension xL and its maximum width in an orthogonal direction yL and the effective size of the leak being given by formula (1): SL=(x2L+y2L)1/2.

The sealing elements have an effective size SE, which is less than the effective size of the leak SL, so that sealing elements (3A) are drawn to the leak locality and caused, by reason of a pressure differential at that locality and attributable to the leak, to move over the leak and reduce the seepage.
