Description

Kondensatorrohr. Die Kondensatorrohre von Kondensatoren, die hinter Dampfmaschinen, Dampfturbinen usw. angeordnet sind, werden gewöhnlich aus Messing verschiedener Zusammensetzungen hergestellt. Namentlich bei Schiffskondensatoren, häufig aber auch bei ortsfesten Kondensatoren werden die Kondensatorrohre: schon nach kurzer Zeit durch Korrosion unbrauchbar und müssen ausgewechselt werden, was namentlich bei Schiffen in fremden Häfen große Kosten und Unbequemlichkeiten verursacht. Man sucht deshalb seit geraumer Zeit nach einem Material für Kondensatorrohre, das sich unter den gegebenen Betriebsbedingungen durch eine hohe Korrosionsbeständigkeit auszeichnet. Solche Versuche waren bisher erfolglos. Rohre aus Beinkupfer wurden zum Teil noch rascher zerstört als Rohre aus Messing oder Bronze; auch Rohre aus rostfreiem Stahl haben sich nicht als geeignet erwiesen, einmal wegen der schlechten Wärmeleitfähigkeit dieses Materials, dann aber, weil rostfreie Stähle wohl gegen Salpetersäure und Atmosphärilien ausgezeichnet beständig sind, nicht jedoch gegen Chloride, Sulfate usw., die häufig in dem Kühlwasser enthalten sind. Man erhält Kondensatorrohre von hoher Korrosionsbeständigkeit und vielfach längerer Lebensdauer, wenn man zu ihrer Herstellung Legierungen verwendet, die 5o bis 8o Prozent Nickel, i o bis .1o Prozent Chrom und o bis 2o Prozent Eisen sowie daneben evtl. 5 bis io Prozent Molybdän oder Wolfram enthalten. Unter Eisen ist möglichst reines Eisen, das entweder gar keinen oder nur Spuren von Kohlenstoff enthält, zu verstehen.Condenser tube. The condenser tubes of condensers that are behind Steam engines, steam turbines, etc. are usually made of brass different compositions. Especially with ship capacitors, but often also with stationary capacitors the condenser tubes are: yes after a short time unusable due to corrosion and must be replaced, what causes great costs and inconvenience, especially for ships in foreign ports. For some time now, people have been looking for a material for condenser tubes that high corrosion resistance under the given operating conditions excels. Such attempts have so far been unsuccessful. Pipes made of leg copper were made partly destroyed more quickly than pipes made of brass or bronze; also pipes out Stainless steels have not proven suitable, once because of the poor Thermal conductivity of this material, but then because stainless steels are probably against Nitric acid and atmospheres are extremely resistant, but not against Chlorides, sulfates, etc., which are often contained in the cooling water. You get Condenser tubes of high corrosion resistance and often longer service life, if alloys are used for their manufacture that contain 5o to 8o percent nickel, 10 to 10 percent chromium and 0 to 20 percent iron and possibly also 5 to 10 percent Percent molybdenum or tungsten. Iron is as pure as possible, that contains either no or only traces of carbon.
