 dadurch erreicht, dass das die Packung von geringer radialer und achsialer Ausdehnung umschliessende, aussenliegende Rohrende durch Verlegung der   Schraubenstützpunkte   oder durch Anordnung nur kleiner lappenartiger Ansätze für die Schraubenstützpunkte (an Stelle der üblichen Flansche) derart ausgebildet ist, dass seine Wärmeausdehnung hindernde Massenanhäufung in Nähe der der Packung vermieden wird. 



   Einige Ausführungsbeispiele des Erfindungsgegenstandes sind durch die Zeichnungen, teilweise im Schnitt, teilweise in Ansicht, dargestellt. 



   Bei sämtlichen Ausführungsformen bezeichnet a den aussen liegenden und b den innen liegenden Rohrteil. die bei den Ausführungsformen nach Fig. 1 bis 8 stopfbüchsenartig ineinandergefügt sind, während sie nach Fig. 9 ein Drehgelenk bilden. Diese beiden Teile   a.   b sind durch die kleine Dichtung c und den nach Art einer Stopfbüchsenbrille wirkenden Ring   d   abgedichtet. 



   Bei sämtlichen Ausführungsformen stellt das die kleine Packung c umschliessende Ende e im wesentlichen eine gerade Fortsetzung der übrigen Wandung des Rohres a dar, an welche der Dampf innen herantritt. Es ist also das die Packung c von aussen umschliessende Material auf das technisch erreichbare Mindestmass gebracht. 



   Um die   Schraubenbolzen f für   das Andrücken des Ringes d gegen die Packung c anbringen zu können, sind verschiedenartige Mittel gewählt. Bei der   Ausführung   nach   Fig. t   sind die Bolzen    j'durch   quer zur Längsrichtung der Rohrachse eingesetzte Stiftschrauben   g   gehalten, während sie bei der Ausführung nach Fig. 2 in einen unterhalb des Ringes d angeordneten, an

 führung nach Fig. 3 greifen die Schraubenbolzenf mit ihrem Kopf unter entsprechende Ansätze j des Teiles   n.   Ähnliche Ausführungsformen veranschaulichen die Fig. 4.   5. 6. 7.   für welche eine nähere Erläuterung nicht erforderlich ist, da die Befestigungsmittel für den Ring d ohneweiters aus der Zeichnung ersichtlich sind.

   Zu beachten ist nur. dass Fig. 6 bei e keine vollständige Flansche darstellt, sondern nur flanschenartige Ansätze, etwa deren drei. Zu Fig. 8 ist zu bemerken. dass   die Schraubenbolzen/hier   in nur kleine Lappen   k   des Teiles a eingeschraubt sind. 



   Bei sämtlichen dargestellten Ausführungsformen ist es   zweckmässig, das   äussere Rohrende an der dem Dampfe ausgesetzten Innenwand mit Rillen oder dgl. zu versehen. um zufolge der dadurch erreichten Vergrösserung der Oberfläche der Innenwand ein schnelleres Anwärmen und demgemäss eine schnellere Ausdehnung des die   Packung umschliessenden   äusseren Rohrendes zu

 achieved by the fact that the outer tube end enclosing the packing of small radial and axial extent by relocating the screw support points or by arranging only small lobes for the screw support points (instead of the usual flanges) is designed in such a way that its thermal expansion hindering mass accumulation near the the pack is avoided.



   Some exemplary embodiments of the subject matter of the invention are represented by the drawings, partly in section, partly in view.



   In all embodiments, a designates the outer tube part and b the inner tube part. which in the embodiments according to FIGS. 1 to 8 are nested like a stuffing box, while according to FIG. 9 they form a swivel joint. These two parts a. b are sealed by the small seal c and the ring d, which acts like a stuffing box gland.



   In all of the embodiments, the end e surrounding the small pack c essentially represents a straight continuation of the remaining wall of the tube a, to which the steam reaches the inside. It is the material surrounding the pack c from the outside that is brought to the technically achievable minimum.



   In order to be able to attach the screw bolts f for pressing the ring d against the pack c, various means are chosen. In the embodiment according to FIG. T, the bolts j 'are held by stud bolts g inserted transversely to the longitudinal direction of the pipe axis, while in the embodiment according to FIG. 2 they are held in a one below the ring d

 3 engage the screw boltsf with their head under corresponding approaches j of part n. Similar embodiments are illustrated in FIGS. 4. 5. 6. 7. for which a more detailed explanation is not necessary, since the fastening means for the ring d without further can be seen from the drawing.

   The only thing to note is. that Fig. 6 at e does not show complete flanges, but only flange-like approaches, approximately three. To Fig. 8 is to be noted. that the screw bolts / are screwed into only small tabs k of part a.



   In all of the illustrated embodiments, it is expedient to provide the outer pipe end on the inner wall exposed to the steam with grooves or the like. in order, as a result of the enlargement of the surface of the inner wall achieved thereby, a faster heating and accordingly a faster expansion of the outer pipe end surrounding the packing
