The present invention relates to an absorber pipe, in particular for solar collectors in solar thermal power plants, having at least one collector mirror (12), comprising a metal pipe (22) for conducting and heating a heat transfer medium, a cladding pipe (24) surrounding the metal pipe (22) for forming an annular space (26) that can be evacuated, a wall (34) extending between the cladding pipe (24) and the metal pipe (22) for sealing the annular space (26), and a retaining device (32) for a getter material (46) or a container (48) filled with getter material (46) or inert gas, having a receiving section (44) for receiving the getter material (46) or the container (48). The retaining device (32) is fastened to the wall (34). The invention further relates to an absorber pipe having at least one collector mirror (12), wherein the absorber pipe comprises a metal pipe (22) for conducting and heating a heat transfer medium, a cladding pipe (24) surrounding the metal pipe (22) for forming an annular space (26) that can be evacuated, and a getter material (46) disposed in the annular space (26) for binding free hydrogen present in the annular space (26), wherein a reflector (94) disposed in the annular space (26) is provided for reflecting radiation (14), said reflector comprising a housing (90) having a support section (92) for fastening and protecting the getter material (46) from the radiation (14). |
