Description
Verfahren zur Herstellung von Metallröhren mit innerer Auskleidung. Gegenstand der Erfindung ist ein Ver fahren zur Herstellung von.Metallröhren mit innerer Auskleidung. Das Verfahren spielt sich folgendermassen ab.
Das durch zentrifugale Wirkung herge stellte Metallrohr wird in rotierende Bewe gung versetzt und alsdann eine flüssige oder halbstarre Masse (z. B. Zement, Beton) in das Innere des Rohres gebracht.
Durch die zentrifugale Wirkung wird nun erreicht, dass die flüssige oder halbstarre Masse gegen die Innenseite des Metallrohres gedrückt, verteilt und züi einem mit dem Me tallrohr enaz verbundenen Ganzen wird. Das in Verfahren beruht auf der Voraussetzung, dass die (durch Zentrifugalkraft liergestell- ten) Rohre eine rauhe Innenfläclie aufweisen.
Wird die halbstarre oder flüssige Masse durch Zentrifugalkraft gegen die Innen fläche gedrückt, während die in der Masse be findliche Flüssigkeit entweicht, so ergibt sich ein sehr fester Zusammenhang zwischen Innen- und Aussenschicht. Man ist in der Lage, die Aussenschieht sehr dünn zu wäli- len, und man erhält vor allem Rohre, die sich zum Beispiel zur Leitung von Flüssig keiten, zur Kanalisation, zur Abfuhr von chemischen Abfallstoffen irgend welcher Art besonders eignen, weil sie innen einmal zu verlässig rostfrei sind, ferner von feiner, gleichmässiger, glatter Innenoberfläche und von fast unbegrenzter Lebensdauer sein können.
Process for the production of metal tubes with inner lining. The invention relates to a method for producing von.Metallröhren with inner lining. The procedure is as follows.
The metal pipe produced by centrifugal action is set in rotating motion and a liquid or semi-rigid mass (e.g. cement, concrete) is then brought into the interior of the pipe.
The centrifugal effect now ensures that the liquid or semi-rigid mass is pressed against the inside of the metal pipe, distributed and becomes a whole that is connected to the metal pipe. The process is based on the prerequisite that the tubes (lined by centrifugal force) have a rough inner surface.
If the semi-rigid or liquid mass is pressed against the inner surface by centrifugal force, while the liquid contained in the mass escapes, there is a very solid relationship between the inner and outer layers. You are able to roll the outer layer very thinly, and you get pipes that are particularly suitable, for example, for conveying liquids, for sewer systems, for the removal of chemical waste of any kind, because they are inside are reliably rust-free, also have a fine, even, smooth inner surface and can have an almost unlimited service life.
