A wellbore assembly includes a first tube and a second tube. The first tube is disposed within a wellbore and has a first end fixed with respect to a wall of the wellbore. The second tube is coupled to a second end of the first tube. The second tube has a third end opposite the coupling and fixed with respect to the wall of the wellbore. The first tube includes a portion of reduced or increased diameter residing between the first end and the second end. The portion of reduced or increased diameter defines an internal diameter that changes, with the first tube under a compression load, to decrease a length of the first tube. The internal diameter changes, with the first tube under a tensile load, to increase a length of the first tube to accommodate changes in length of the first tube or the second tube or both.
