Abstract (en)
[origin: EP2644821A1] The present invention relates to a an annular barrier for providing a barrier between a casing and a borehole or between a casing and a surrounding casing. The annular barrier comprises a tubular part for forming part of the casing, having an axial extension; an expandable sleeve connected with and surrounding the tubular part and defining an expandable space; and an opening fluidly connected with the expandable space for letting fluid from within the tubular part to the expandable space to expand the sleeve. The annular barrier further comprises a tubular element connecting the sleeve with the tubular part, having an extension in the axial extension and a first end part connected with the tubular part and a second end part connected with the expandable sleeve. The first end part is arranged closer to the opening along the axial extension of the tubular part than the second end part.
