| Zusammenfassung: | A decomposable sealing device is described for use in liquid-filled pipes or boreholes, which is characterised in that the sealing device comprises a sleeve-shaped element which envelops a number of strata completely or partly in the pipe's radial and a longitudinal direction, comprising layered division of a number of decomposable strata and a number of closed liquid-filled chambers arranged between the strata and where the sleeve-shaped element comprises a body which can be rearranged to establish connection between the respective chambers and one or more grooves in the inner wall of a pipe. A method for decomposing the sealing device is also described. |
