Abstract
The invention relates to a sealing element (1) with inflatable bellows (10) for sealing piping. Said sealing element can be e.g. cylindrical in shape and said bellows (10) can be provided with two recesses (14a, 14b) containing a gel (11). When the bellows are inflated, the gel (11) encompasses e.g. uneven areas on the inner wall of the piper or cables in the pipe in such a way as to provide a seal.
Claims18
A sealing element for sealing pipelines, the sealing element having an inflatable bellows which, in an inflated state, causes the sealing element to bear against an inner wall of the pipeline, wherein, on an outer side of the bellows facing an inner wall of the pipeline, at least on sections of a circumference of the bellows, the bellows carries a dimensionally stable, easily deformable gel forming part of the sealing element which, in an inflated state of the bellows, comes into direct sealing contact with the inner wall of the pipeline and which, in a deflated state of the bellows, returns to an original form of the gel on the bellows.
The sealing element according to claim 14, wherein, in cross section, the bellows is essentially one of a circle, an oval or an egg shape with respect to the outer side of the bellows.
