Abstract

An annular barrier (1) for providing a barrier between a casing (3) and a borehole (5) or between a casing and a surrounding casing, comprising: - a tubular part (6) for forming part of the casing, having an axial extension, - an expandable metal sleeve (7) connected with and surrounding the tubular part and defining an expandable space (13), and - an opening (11) fluidly connected with the expandable space for letting fluid from within the tubular part to the expandable space to expand the sleeve, wherein the annular barrier further comprises a tubular metal element (20, 20A) connecting the sleeve with the tubular part, having an extension in the axial extension and a first end part (21) connected with the tubular part and a second end part (22) connected with the expandable sleeve, and wherein the first end part is arranged closer to the opening along the axial extension of the tubular part than the second end part. Furthermore, the invention relates to an annular barrier system and to a method for providing a barrier between a casing and a borehole or between a casing and a surrounding casing.
