Description

Gußeisernes Vorwärmerrohr mit an einem Ende angegossenem Bund. Uni gußeiserne Vorwärmerrohre für hohen Druck verwenden zu können, werden dieselben in Schleuderguß hergestellt. Das bedingt, daß nur an einem Ende des Rohres ein Bund zur Auflegung einer Befestigungsbrücke angegossen werden kann, während das andere Ende glatt bleiben muß.Cast iron preheater pipe with a collar cast on one end. University Being able to use high pressure cast iron preheater pipes become the same manufactured in centrifugal casting. This means that only one end of the tube has a collar can be cast to lay a mounting bridge, while the other Must stay smooth at the end.

Da aber auch'dieses Ende durch eine Befestigungsbrücke mit seinem Sammelkasten verbunden werden muß, so wird gemäß der Erfindung ein passender Ring mit dem Rohr dadurch fest verbunden, daß er entweder aufgeschweißt oder aber in eine entsprechende Nute des Rohres aufgeschrumpft wird.But there too, this end by a fortification bridge with his Collector box must be connected, a matching ring according to the invention firmly connected to the pipe in that it is either welded or in a corresponding groove in the pipe is shrunk on.

In der Zeichnung ist üi Abb. i ein solches Rohr mit aufgeschweißtem Bundring, in Abb. 2 mit aufgeschrumpftem Bundring dargestellt. a ist das Gußrohr, dessen oberes Ende b und dessen unteres Ende c korrisch abgedreht ist, zwecks Einpressung in die zugehörigen Sammelkästen. An dein oberen Ende befindet sich ein angegossener Bund d, während an dem unteren Ende der Bund elmittels der Schweiße f aufgeschweißt ist. Man kann auch gemäß Abb. 2 den Bund e2 in eine entsprechende Ausdrehung auf das Rohr a, aufschrumpfen.In the drawing, such a tube with a welded-on collar ring is shown in Fig. 2, with a shrunk-on collar ring in Fig. 2. a is the cast iron pipe, the upper end of which b and the lower end of which c has been twisted off, for the purpose of being pressed into the associated collecting tanks. At its upper end there is a cast collar d, while at the lower end the collar is welded on by means of the weld f . You can also shrink the collar e2 into a corresponding recess on the tube a, as shown in Fig. 2.
