Abstract:
1. A system for repairing a leakage in a pipeline, the system comprising: a first body conforming to a size of the pipeline; a second body conforming to the size of the pipeline; and a sealing material comprising a hardener and at least one filler; wherein the second body is mechanically unconnected to the first body, such that the second body is moveable in the pipeline independently of the first body, and wherein the hardener and the at least one filler are selected such that, the hardener and the at least one filler are pre-mixable before insertion in the pipeline, and the sealing material, comprising a mixture of the hardener and the at least one filler, is configured to be located in the pipeline between the first body and the second body such that, when pressures are applied to the first body and the second body in opposite directions and the sealing material is compressed therebetween, the sealing material is configured to move along the pipeline along with the first body and the second body, thereby filling a crack or hole in the pipeline that is causing the leakage without substantially adhering to an inner surface of the pipeline in areas other than an area of the crack or hole.
