摘要：A gas-tight furnace, in particular a vacuum furnace, has a hood-shaped upper section and a bottom that each possess an essentially elliptical or circular coupling flange. The coupling flanges face one another, and can be sealed together gas-tight due to a circumferential seal. Each coupling flange is formed by two essentially concentric tubes which are permanently connected, for example by welding.
