Abstract
Junction for vertical discharge or ventilation ducts, characterized in that it is constituted essentially by a first sleeve having in half approximately an internal diameter substantially equal to the external of the tubes to be joined and for the remaining part an external diameter substantially equal to the internal of the tubes. Tubes, and by a second coaxial sleeve having an internal diameter substantially equal to the external one of the tubes, said second sleeve contours the smaller diameter part of the first sleeve and extends partially over the larger diameter part of the first one to which it has remained united by welding, printing or other capable system.
