Hütchen eingesetzt sind. Die Röhren A, A werden, wie üblich, mittels eines Rohrerweiterungs- werkzeugs befestigt ; die Öffnungen, durch welche letzteres zwecks Aufwalzens (Umbördeln) der   Röhrenenden   eingeführt war, werden gemäss vorliegender Erfindung mit metallenen Hütchen
B, B verschlossen. 



   Das Verschliessen der Öffnungen mit diesen metallenen Hütchen, die mittels eines Rohr- erweiterungswerkzeuges befestigt werden, hat gegenüber anderen bis jetzt bekannten Vor-   richtungen,   wie mit Gewinde versehene Pfropfen und mittels Bolzen zu befestigende Deckel, folgende Vorteile :   l.   Vollkommene hermetische Dichtheit der Verbindung,
2. die Möglichkeit, die Röhren beliebig nahe aneinander anzuordnen.

  Device for closing round openings in metal walls.



   According to the present invention, to close round openings through which pipe expansions or other tools are inserted, metal pipes are used for the purpose of fastening metal pipes in the walls of such metal chambers, which are used as components of steam superheaters, various liquid preheaters, steam boilers and similar apparatus
Applied hats, which are also attached by means of a pipe expansion or a similar tool 'tools.



   The drawing shows part of a collecting chamber of an ordinary tubular steam superheater, u. FIG. 1 shows the chamber in section, the section being taken through the axis of one of the tubes; Fig. 2 is a side view of the side in which the
Cones are used. The tubes A, A are fastened, as usual, using a tube expansion tool; the openings through which the latter was inserted for the purpose of rolling on (flanging) the tube ends are, according to the present invention, with metal caps
B, B closed.



   The closing of the openings with these metal caps, which are fastened by means of a pipe expansion tool, has the following advantages over other devices known up to now, such as threaded stoppers and lids to be fastened by means of bolts: Perfect hermetic tightness of the connection,
2. the possibility of arranging the tubes as close to one another as desired.
