Description

Verfahren zur Herstellung von kupferplattierten Rohrenden Ein neinfaches Verfahren der Einlagerung eines Kupferrohres in :ein Eisenrohr oder der Ummantelung eines Eisenrohres mit einem Kupferrohr besteht darin, :daß das lose in das Eisenrohr oder um dasselbe ;gelegte Kupferrohr durch Aufwehen mittels Diornnes oder Einengen mittels Matrize biewirkt wird. Um eine Überbeanspruchung des Kupfers zu vermeiden, hat man ;auch die Preßflächen des Dornes, der Matrize od. dgl. aus Leder oder gleichwertigem nachgiebigem Werkstoff gestaltet. Durch die Unebenheiten im Stahlrohr wird das Kupferrohr überall zur Anlage gebracht. Es tritt hierbei jedoch keine innige und unlösliche Verbindung -der beeiden Materialien ein. Gemäß der Erfindung werden Stahlrohrenden mit seiner innig -und unlös.liclh verbundenen Kupferplattierung dadurch versehen, daß beispielsweise für die Innenplattierung ein Kupferrohr in das Stahlrohr @einges:choben, hierauf ein Stahldorn eingeführt und das Rohrende dann mit dem fest zur Anlage gebrachten Kupferrohr und mit dem inliegenden Stahldorn ,auf Diffusionstemperatur (85o bis iooo° C) kurz erwärmt wird. Nach dem Erkalten wird der Stahldorn paus dem Rohrende herausgezogen. Für den Stahldorn verwendet man zweckmäßig leinen zunderbeständigen Werkstoff. Die Länge des Stahldornes reicht zweckmäßig über die Länge der Plattierung hinaus, damit keine,oxydbildenden Gase Feindringen können. Ebenso wird der Stahldorn mit Mitteln, beispielsweise mit Kreide, @eing eriebün, um das Drifundieren des Kupfers zum Stahldorn zu Vermeiden.Process for the production of copper-clad pipe ends A simple one Method of embedding a copper pipe in: an iron pipe or sheathing An iron pipe with a copper pipe consists in: that that loosely in the iron pipe or around the same; laid copper pipe by blowing up by means of diornnes or narrowing is acted on by means of a die. To avoid overstressing the copper, one has; also the pressing surfaces of the mandrel, the die or the like made of leather or equivalent flexible material designed. The copper pipe becomes through the unevenness in the steel pipe brought to the facility everywhere. However, there is no intimate and insoluble one Connection of the two materials. According to the invention, steel pipe ends provided with its intimately and inextricably connected copper plating, that, for example, a copper pipe is pushed into the steel pipe @einges: for the inner plating, then a steel mandrel is inserted and the end of the pipe is then firmly attached to the end of the pipe Copper pipe and with the steel mandrel inside, to diffusion temperature (85o to iooo ° C) is briefly heated. After cooling down, the steel mandrel is paused from the end of the pipe pulled out. For the steel mandrel, it is advisable to use non-scaling linen Material. The length of the steel mandrel expediently extends over the length of the cladding in addition, so that no, oxide-forming Gases can penetrate. as well is the steel mandrel with means, for example with chalk, @eing eriebün to the Avoid drifting of the copper to the steel mandrel.

Bei seiner Außenplattiere ng tritt Beine Matrize an Stelle des Stahldornes, die vor dem Üherschieben auf das mit seinem Kupferrohr versehene Stahlrohr ebenfalls zum Kupferrohr hin -mit Kreide eingerieben wird. Brei Innen- und Außenplanierungen kommen sowohl Stahldorn als such die Matrize gleichzeitig zur Wirkung.With its outer plating, the die takes the place of the steel mandrel, the one before it was pushed onto the steel pipe provided with its copper pipe is rubbed with chalk towards the copper pipe. Pulp inside and outside planes Both the steel mandrel and the die come into play at the same time.

Die Vorteile der Erfindung ;gegenüber dien Bekannten liegen darin, daß die Stahlrohrenden außen oder innen homogen, id. h. fest und unlöslich mit einer Kupferplattierung versehen werden können. D0.e so plattiertem Endgen lassen sich wie normale Rohre verarbeiten, beispielsweise einwalzen, bördehi usw. Es besteht keine Gefahr, daß sich Kupfer und Stahl trennen.The advantages of the invention; compared to the acquaintances are: that the steel pipe ends are homogeneous outside or inside, id. H. solid and insoluble with a Copper plating can be provided. D0.e so plated end gene can process like normal pipes, for example roll in, bördehi etc. It consists no risk of copper and steel separating.
