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.

Abstract: A method for production of lined gaskets or gasket inserts with which a pasty substance is arranged between the sealing surfaces (or correspondingly developed forms) and separated from these by two external layers, and hardened between the form-producing sealing surfaces. The pasty substance preferably contains a filler of quartz powder whose void fraction is filled with a 2-component artificial resin. The pasty substance can be applied with the assistance of a spray gun. A preferred form of construction of such a gasket contains a hardened material layer and a corrugated ring adjoining it, which, along an inner peripheral area are surrounded by a band-shaped shell and are arranged between two gasket insert rings, which for their part are surrounded by a customary shell of polytetrafluoroethylene or such-like.
