Definitions

  • the invention relates to a transport line with ceramic inner insulation for guiding hot fluids, which has hollow hollow bodies surrounding the flow space of the transport line within an outer wall for insulation, which is enclosed on its side facing the outer wall by tensioning elements which enclose the hollow bodies preload on unloaded pressure.
  • Internal insulation for transport lines is required in order to protect the outer walls of the transport line, which are usually made of metallic materials and are subjected to internal pressure, from overheating. Ceramic foils or fiber materials and solid ceramic insulation are known for internal insulation. The latter have proven particularly useful for prestressed concrete tanks.
  • German Offenlegungsschrift 1 804 143 German Offenlegungsschrift 1 804 143.
  • sealing elements are required at least at the joints between the individual hollow bodies in the transport line in order to suppress the occurrence of parasitic gas flows in the space between the inner insulation and the outer wall.
  • the object of the invention is to avoid these disadvantages and to provide a transport line, the ceramic, prestressed inner insulation in the transport line without impairing the desired strength properties of the inner wall stressed inner wall and without influencing the stress on the wall as a result of the change in expansion during operation - And the voltage condition of the inner insulation can be used in a simple manner so that gas flows outside the intended flow space in the transport line are avoided.
  • the transport line has, within an outer wall 1, a ceramic inner insulation surrounding the flow space 2 of the fluid and designed as a hollow body 3.
  • a steel tube is provided as the outer wall 1.
  • the inner insulation is formed by a plurality of segments, of which the interconnected segments 3a to 3c are shown in FIG. 2.
  • the ceramic hollow body 3 is enclosed on its side facing the outer wall 1 by clamping elements 5, which prestress the hollow body under pressure.
  • Rings are provided as tensioning elements 5, which are shrunk onto the nested segments of the hollow body 3 in the usual way to achieve the desired prestressing. This creates closed, hollow-cylindrical insulating pieces that can be inserted axially into the transport line. Centering 6 ensure mutual alignment of the lined up hollow body.
  • the clamping elements 5 are welded gas-tight with a tight peripheral seam 7 on a thin intermediate wall 8.
  • the intermediate wall 8 is - likewise gas-tight - connected to the outer wall 1 and, in the exemplary embodiment, welded to the outer wall 1 at welding points 7 '.
  • the intermediate wall 8 advantageously also reduces the space between the insulation and the outer wall, so that heat losses and asymmetries in the temperature distribution - caused by the occurrence of free convection in the space - are reduced.
