Abstract

The invention relates to an expansion joint (1) for joining two adjacent parts of a pipe. The expansion joint (1) comprises an expansion bellows (5), an expanded wall (2) and an inner sleeve assembly (8). The expanded wall (2) comprises a first wall part (3) and a second wall part (4), wherein the first wall part (3) and the second wall part (4) are spaced apart from each other axially by an axial gap. The expansion bellows (5) is connected to the first wall part (3) and to the second wall part (4) such that the axial gap between the first wall part (3) and the second wall part (4) is closed and such that the first wall part (3) and the second wall part (4) are connected flexibly. The expanded wall (2) and the inner sleeve assembly (8) limit at least one sealed chamber (9, 10) between each other, and the at least one sealed chamber (9, 10) is filled by a first gas.
