ABSTRACT:
The absorber pipe (1), especially for a parabolic collector for a solar heat collecting apparatus, is described. The absorber pipe (1) includes central metal pipe (3), a glass sleeve tube (2) surrounding the nine so that an annular space (4) is formed between them and an expansion compensating device connecting the central metal nine and a glass-metal transitional element (5) on a free end of the sleeve tube (2). The expansion compensation device (10) connects the metal pipe and sleeve tube, so that they can slide relative to each other, and includes folding bellows (11) for that purpose. Furthermore it also includes a connecting element (15), which has either a cylindrical or a conical section (17,18,18″) and which connects an interior end of the folding bellows with the metal pipe.
