ABSTRACT:
Tubular components made out of quartz glass or fused quartz, such as tubes, bells, hoods, or pans, with a flange fused or welded onto them are known. To improve cooling such a tubular component, especially the sealing surfaces of the flange, heat conduction and heat radiation in the vicinity of the flange are extensively avoided and, to make it possible to create long-diameter tubular components, the flange is designed hollow and narrow-walled, whereby a coolant, preferably water or a gas, can be conveyed through the hollow space in one preferred embodiment for purposes of interior cooling or the hollow space can be packed with a heat-insulating material.
