  • the invention relates to a method for producing such a pipeline
  • Such pipelines are known from the prior art and are used for example in power plants, incinerators and the like. In these applications, it is often necessary to transport hot gases and / or hot liquids or vapors while still achieving satisfactory insulation.

  • the longest-used systems are internally insulated bricked pipes with refractory and thermal insulating stones.

  • the materials are often close to the Operated material load limit, so that in order to ensure the strength, high wall thicknesses are required, which is associated with high costs. Due to the required mounting of the inner tube to the outer tube there is a risk of thermal bridge formation. Also particularly disadvantageous proves to be the insufficient dimensional stability with fast pressure drop.
  • Ceramics are distinguished, for example, by their excellent mechanical strength and strength even at high temperatures. They are extremely wear-resistant and show excellent sliding properties. They also have excellent heat resistance and are particularly resistant to acids and other chemical or chemo-electric attacks as well as to corrosion and can therefore be used in many areas.
  • EP 96791 A1 describes an insulation with inner non-pressure-tight tube for gas conduction made of a heat-resistant ceramic, an outer metallic pressure tube and a built-up of several bowls insulating layer of a mineral insulating material. To avoid gas flow into the insulation, additional sealing elements of mineral fibers are provided.
  • DE3144857 describes a possibility to fix the ceramic inner tube coaxially, so that the relative position of the two tubes is maintained to each other.
