Description

Eine sichere Abhilfe gegen das Auftreten von Korrosionserscheinungen bei Berohrungen von Kühlern und Kondensatoren ist die Verwendung von Rohren aus mittel- und hochlegierten Stählen oder von Rohren aus Bronze, Messing und Kupfer.A reliable remedy against the occurrence of corrosion when piping on radiators and capacitors is the use of pipes made of medium and high alloy steels or of pipes made of bronze, brass and copper.

Um diese hochwertigen Materialien einzusparen, ist man dazu übergegangen, Messing- oder Cuplattierte Rohre zu verwenden (innen oder außen oder innen und außen plattiert). Diese Rohre habenIn order to save on these high-quality materials, people have switched to brass or cup-plated Use pipes (inside or outside or clad inside and outside). Have these tubes

ίο sich einwandfrei bewährt, da sie sich auch ohne Schwierigkeiten in die in Frage kommenden Bodenplatten einwalzen lassen.ίο has proven itself flawlessly, as it can also be used without Allow difficulties to be rolled into the floor slabs in question.

Um auch die wertvollen Plattierungen zu sparen, hat man auch schon brennlackierte oder kunstharzisolierte Rohre verwendet. Für Zwecke des Wärmeaustausches und überall dort, wo die Rohrenden eingewalzt werden, können die so isolierten Rohre nicht gebraucht werden, da die Überzüge beim Einwalzen abspringen.In order to save on the valuable cladding, you also have stove-enamelled or synthetic resin-insulated ones Pipes used. For the purpose of heat exchange and wherever the pipe ends are rolled in, the pipes insulated in this way cannot be used because the coatings are rolled in jump off.

ao Gemäß der Erfindung werden diese Nachteile dadurch vermieden, daß die Rohrenden zwischen Einbrennlack und Stahlrohr eine nicht rostende Schicht wie Kupfer od. dgl. besitzen. Die Plattierungsschicht reicht hierbei vom Rohrende aus so weit, daß an den zerstörten Stellen des Lacks das Stahlrohr selbst von den zerstörenden Mitteln nicht angegriffen werden kann.According to the invention, these disadvantages are avoided in that the pipe ends between stoving varnish and steel pipe have a rustproof layer such as copper or the like. The plating layer extends from the end of the pipe so far that the steel pipe is at the damaged areas of the paint cannot be attacked even by the destructive means.

Nach der Abbildung, die einen Schnitt durch eine Einwalzstelle darstellt, ist α die Bodenplatte, b das einzuwalzende Rohr, c die Isolierung des Rohres (Einbrennlack, Kunstharz od. dgl.), d ist die Plattierung aus nichtrostendem Material, wie Kupfer, Messing od. dgl. Die gestrichelt angedeuteten Isolierungen bezeichnen die Zerstörungsstellen. Je nach den Verhältnissen wird die Plattierung nur innen oder nur außen oder innen und außen angewandt.According to the figure, which shows a section through a rolling point, α is the base plate, b the tube to be rolled, c the insulation of the tube (stoving varnish, synthetic resin or the like), d is the cladding made of rustproof material such as copper, brass or the like The insulation indicated by dashed lines denotes the points of destruction. Depending on the circumstances, the plating is used only inside or only outside or inside and outside.

Der Vorteil gegenüber dem Bekannten liegt in einer einwandfreien Isolierung der Rohrenden.The advantage over the known is a perfect insulation of the pipe ends.
