 durch die Rohrplatte enger oder weiter zusammengefasst werden. Der Durchtritt durch die Rohrplatte erfolgt in Richtung der Flächennormalen. 



   In Fig. 2 ist ein Detail aus Fig. l dargestellt. An der Klemmstelle des Rohres-l-weist dieses eine   Rohrwandverstärkung--6--auf.   Diese Verstärkung wird gemäss Fig. 2 dadurch erzielt, dass an der Klemmstelle ein Rohr--8--über das   Wärmetauscherrohr--l--geschoben   wird, welches dann die äusseren   Vorsprünge --11-- bildet.   Die Verbindung der beiden Rohre erfolgt zweckmässigerweise mittels Hartlötung oder Schweissung. In Fig. 3 ist eine variierte Konstruktion dargestellt. An dem   Wärmetauscherrohr-l-wird   an der Klemmstelle ein.   Kragenstück --9-- mit   zwei Absätzen   - -10-- angeschlossen,   die die   Vorsprünge --11-- bilden.   



   Die Rohrfixierung mittels überschubmuffen oder Einschweisskragen mittels einer Rohr-oder Gegenplatte ist in den Fällen vorteilhaft, wo keine absolute Dichtheit erforderlich ist bzw. wo sogar ein kontrollierter Gasaustritt erwünscht ist. Diese Konstruktion hat besondere Vorteile bei einer sekundären Druck-Barriere eines Wärmetauschers für nukleare Zwecke. 



   Die Erfindung ist auf die in den Zeichnungen dargestellten Konstruktionen nicht eingeschränkt. 



  So können selbstverständlich auch Klemmverbindungen verwendet werden, die eine Dichtheit garantieren. Fernerhin ist es möglich, die Rohre an der Stelle ihres Durchtrittes durch die Rohrplatte zu klemmen.

 be brought together closer or wider by the tube plate. The passage through the tube plate takes place in the direction of the surface normal.



   In Fig. 2 a detail from Fig. 1 is shown. At the clamping point of the pipe-1-this has a pipe wall reinforcement - 6 -. According to FIG. 2, this reinforcement is achieved in that a tube - 8 - is pushed over the heat exchanger tube - 1 - at the clamping point, which then forms the outer projections --11--. The connection of the two tubes is expediently carried out by means of brazing or welding. In Fig. 3, a varied construction is shown. At the clamping point on the heat exchanger pipe-l-a. Collar piece --9-- connected with two paragraphs - -10--, which form the projections --11--.



   The pipe fixing by means of sleeve sleeves or weld-in collars by means of a pipe or counterplate is advantageous in cases where absolute tightness is not required or where even a controlled gas outlet is desired. This construction has particular advantages in a secondary pressure barrier of a heat exchanger for nuclear purposes.



   The invention is not restricted to the constructions shown in the drawings.



  Clamp connections can of course also be used, which guarantee tightness. Furthermore, it is possible to clamp the tubes at the point of their passage through the tube plate.
