aus Aluminium oder Aluminiumverbindungenmade of aluminum or aluminum compounds

Die Erfindung betrifft eine Verbesserung, die bei der Verwendung von Rohrleitungen und verschiedenen !'eilen in sanitären Einrichtungen, wie z.B. i/armwasserbereitern oder anderen Einrichtungen, in denen eine Versorgungsflüssigkeit strömt, angewandt v/ird.The invention relates to an improvement in the use of pipelines and various! 'Rush in sanitary Facilities such as i / water heaters or other facilities, in which a supply liquid flows is applied.

Die Verwendung von Werkstoffen wie Kupfer und seine Verbindungen ist bekannt, aber sie verursacht in gewissen i'ällen Nachteile, die u.a. durch die Korrosion bedingt sind, welche dort auftritt, wo zwei verschiedene Metalle in engen Kontakt miteinander gebracht werden, und die durch eine bekannte elektro-chemische Reaktion hervorgerufen wird, die an der Kontaktstelle entsteht.The use of materials such as copper and its compounds is known, but in certain cases it causes disadvantages due, among other things, to the corrosion which occurs where two different metals are brought into close contact with one another and which is caused by a known one electro-chemical reaction is caused, which occurs at the contact point.

Ein anderer Uachteil ist durch die Flüssigkeit bedingt, mit der diese Werkstoffe in Berührung kommen, wie das Haushaltswasaer, v/elches je nach dem Gebiet, in dem es hergestellt wird, mehr oder weniger Kalkstein enthält.Another disadvantage is due to the liquid, with who come into contact with these materials, such as household water, v / elches contains more or less limestone depending on the area in which it is produced.

Andererseits werden gewisse Metalle, wie z.B. Kupfer, durch gewisse wirtschaftliche, geographische oder andere Paktoren in der Verwendung teuer und belasten bisweilen erheblich den Selbstkostenpreis gewisser Einrichtungen.On the other hand, certain metals, such as copper, get through certain economic, geographic or other factors are expensive to use and sometimes place a considerable burden on the company Cost price of certain facilities.

Als leichteren und weniger kostspieligen v/erkstoff als Kupfer kann man Aluminium und seine Verbindungen verwenden. Jedoch verursacht dieses bei seiner Verwendung in nicht behandeltem Zustand ebenfalls gev/isse der obengenannten Nachteile, wie den Angriff durch die feuchten Medien und die elektrochemische Korrosion.As a lighter and less expensive material than copper you can use aluminum and its compounds. However, this causes when used in an untreated condition also suffer from the above-mentioned disadvantages, such as attack by the moist media and the electrochemical Corrosion.

Zur Vermeidung dieser Nachteile ist es bekannt, das Aluminium anodisch zu behandeln, wodurch eine dünne Aluminiumoxydschicht von einigen hundertstein Hikron auf die Oberfläche gebracht wird. Jedoch reicht das Aufbringen dieser außerordentlich dünnen Schicht nicht aus, um einen wirksamen Schutz des Aluminiums in dem Fall zu gewährleisten, wo es als Hohr oder beliebiges Teil bei der Herstellung sanitärer Einrichtungen, wie z.B. Warmwasserbereitern, in denen Versorgungswasser strömt, verwandt wird.To avoid these disadvantages, it is known that aluminum to be treated anodically, whereby a thin aluminum oxide layer of a few hundred stone hikron is applied to the surface will. However, the application of this extremely thin layer is not sufficient to effectively protect the aluminum in to ensure the case where it is used as a Hohr or any part in the manufacture of sanitary facilities, such as water heaters, in which supply water flows is used.

Damit Rohre und verschiedene Teile aus Aluminium und Aluminiumverbindungen in derartigen Einrichtungen verwandt werden können, werden im Hinblick auf eine Verringerung ihres Selbstkostenpreises und Gewichtes unter Vermeidung der vorstehend genannten Nachteile die Rohre und verschiedene Teile erfindungsgemäß mit einer harten anodischen Oxydation so behandelt, daß das Aufbringen einer gegenüber bekannten Verfahren verhältnismäßig dicken Aluminiumoxydschicht auf die so behandelten Teile gewähr-With it pipes and various parts made of aluminum and aluminum connections can be used in such facilities with a view to reducing their cost price and weight while avoiding the disadvantages mentioned above, the pipes and various parts according to the invention a hard anodic oxidation treated so that the application of a compared to known processes is proportionate thick aluminum oxide layer on the parts treated in this way

leistet ist, wobei die Dicke der Schicht vorzugsweise etwa 25 Jdkron beträgt.makes, the thickness of the layer is preferably about 25 Jdkron.

Das Aufbringen einer Aluminiumoxydschicht dieser Dicke bietet als Vorteile, daß auf den Rohren und verschiedenen Teilen eine gute Isolierung gegenüber der Bildung von Kalksteinablagerungen auf ihrer Oberfläche gewährleistet ist, daß der Angriff dieser Oberflächen durch die strömenden Flüssigkeiten vermieden und ihre Korrosion an der Stelle verhindert wird, wo sie Kontakt mit Organen und Teilen aus. unterschiedlichem Metall haben.The application of an aluminum oxide layer of this thickness offers the advantages that one on the pipes and various parts good insulation against the formation of limestone deposits on their surface it is ensured that the attack on these surfaces by the flowing liquids is avoided and Their corrosion is prevented at the point where they come into contact with organs and parts. different metal.
