Patentirt im Deutschen Reiche vom 29. April 1880 ab.Patented in the German Empire on April 29, 1880.
Die Siederöhren der Röhrenkessel bestehen bislang aus Messing, Eisen oder Stahl, und, wenngleich in sehr seltenen Fällen, aus Kupfer.The boiling tubes of the tubular boilers have so far been made of brass, iron or steel, and, albeit in very rare cases, made of copper.
Die Röhren aus Messing haben den Nachtheil einer durch die Weichheit des Materials begründeten, gröfseren Abnutzung an den inneren Wandungen durch Asche und Kohle, welche die Flamme mitreifst. Dadurch kommen diese Röhren natürlich öfter zum Ersatz, weil die geschwächten Wandungen dem äufseren Drucke des Dampfes nicht mehr widerstehen, und es sind somit die Erhaltungs- und Erneuerungskosten bei dem ohnehin theueren Messingmateriale sehr beträchtlich. Hingegen bleibt die vom Wasser berührte Fläche gut conservirt, und es treten keine örtlichen Rostungen ein, weil das Wasser dieses Röhrenmaterial wenig oder gar nicht angreift.The brass tubes have the disadvantage of being due to the softness of the material, Greater wear and tear on the inner walls from ash and coal, which the flame carries along with it. This is how these come Tubes, of course, are often used as replacements because the weakened walls add to the external pressure no longer withstand the steam, and so there are maintenance and renewal costs very considerable with the already expensive brass material. On the other hand, the from The water in contact with the surface is well preserved, and local rusting does not occur because that Water attacks this tube material little or not at all.
Die Eisen- und Stahlröhren erleiden, im Gegensatze zu den Messingröhren, an den inneren Wandungen durch die die Röhren durchziehenden Kohlenstückchen und die Asche wegen der Härte des Materials nur eine sehr geringe Abnutzung. Hingegen wird deren äufsere Fläche durch den Rost sehr angegriffen, insbesondere bilden sich sogenannte Rostnester, wodurch die Röhren in nicht langer Zeit lecken und ausgewechselt werden müssen. Hingegen sind die Eisenröhren sehr wohlfeil, so dafs der Gedanke immer dahin gehen mufs, die Benutzung dieser Röhren möglich zu machen bezw. deren Mängel zu beseitigen.The iron and steel tubes, in contrast to the brass tubes, suffer from the inner walls through the pieces of coal running through the tubes and the ashes very little wear due to the hardness of the material. On the other hand, their The outer surface is very attacked by the rust, in particular so-called rust nests are formed, whereby the tubes leak and have to be replaced in a short time. On the other hand the iron tubes are very cheap, so that the thought must always go there, the use to make these tubes possible respectively. to eliminate their shortcomings.
Vollkommen entsprechende Röhren müssen demnach derartig beschaffen sein, dafs die Innenfläche durch das Feuer weder mechanisch noch chemisch, und die Aufsenfläche durch das Wasser nicht angegriffen wird, d. h. man wird eine Röhre aus verschiedenem Material construiren müssen.- Der Erfinder wendet deshalb Eisen- oder Stahlröhren an, deren äufsere Fläche mit Kupfer überzogen ist.Corresponding tubes must therefore be of such a nature that the Inner surface by the fire neither mechanically nor chemically, and the outer surface by the Water is not attacked, d. H. a tube will be constructed of various materials must.- The inventor therefore uses iron or steel pipes, their outer Surface is coated with copper.
Die Herstellung des Ueberzuges geschieht nach einer der bekannten Arten oder in folgender Weise: Es wird ein Kupfer- oder Messingstreifen von der Länge der eisernen Röhre und von einer etwas gröfseren Breite als der dreifache Durchmesser unter die Röhre seiner Länge nach gelegt; dieser Streifen wird um die Röhre gebogen, die Ränder desselben werden in einander gefalzt und der Falz wird gelöthet. Jetzt wird die so in das Kupfer- oder Messingblech ganz eingehüllte eiserne Röhre durch ein Locheisen gezogen, wobei sich das Kupfer- oder das Messingblech ganz fest an die Oberfläche der Eisenröhre anlegt, so dafs bei Wiederholung dieser Procedur Messing oder Kupfer und Eisen ein Stück bildend erscheinen.The production of the coating takes place in one of the known ways or in the following way Way: It will be a copper or brass strip the length of the iron tube and of a width somewhat greater than three times the diameter under the tube of its length after laid; this strip is bent around the tube, the edges of the same become one inside the other folded and the fold is soldered. Now this is done in the copper or brass sheet completely enveloped iron tube pulled through a punch, whereby the copper or the Brass sheet placed firmly against the surface of the iron tube, so that on repetition this procedure brass or copper and iron appear to form one piece.
Zur Ausführung dieser Arbeiten können die gewöhnlichen Werkzeuge und Hülfsmaschinen benutzt werden.The usual tools and auxiliary machines can be used to carry out this work to be used.
