ABSTRACT:
An arrangement to increase the thermal fatigue resistance of glass tubes having fluid flowing therethrough and being pressure-loaded. This arrangement comprises a glass tube, into which an interior component is inserted. The interior component can be designed as thin-walled tube or tubular component. In accordance with a first example the cavity enclosed by the interior component is hydraulically connected with the interior of the glass tube. The wall thickness of the interior component is smaller than the wall thickness of the glass tube and the interior component is partially free from a direct heat connection with the glass tube. In accordance with a second example the interior component increases the wall thickness of the glass tube. In this case the interior component is touching the interior circumference of the glass tube.
