使用隔热机构通过其绝缘，另一方面出于其经济生产可能性决定了一只手。 用于制造绝热体，例如一种特别简单的过程 管与，尤其是金属，内部和，尤其是金属，外护套，以及通过此形成间隙填充有多孔的，颗粒状和/或多孔粉状绝缘材料，抽真空并密封真空密封，就是之间的空间 于是绝缘材料从容器引入真空下在真空下间隙和密封的内部和外部护套被抽真空。

The use of thermally insulated bodies determined the one hand from their insulating ability and in part of their economic production possibilities. A particularly simple process for producing a thermally insulated body, for example the pipe, with a, particularly metallic, interior and, in particular metallic, outer sheath, wherein the filled through this formed gap with a porous, particulate and / or porous pulverulent insulating material, evacuated and is vacuum sealed, is that the gap between the inner and outer jacket evacuated whereupon the insulating material introduced from a container under vacuum in the vacuumized gap and it is closed.
