ABSTRACT:
A jacket for an enameled vessel with a lower outlet nozzle is described comprising an upper weld ring welded along the outer circumference of the vessel, and comprising a lower weld ring surrounding the lower outlet nozzle, and also the jacket as such. The upper weld ring is conically tapering to its lower end, and the lower end of the lower weld ring is shaped cylindrically. Therefore, the upper end of the jacket can be easily welded with the outer side of the lower end of the upper weld ring, since the lower end of the jacket can be moved into a proper position along the cylindrical end of the lower weld ring.
