Description

Technisches Gebiet Technical area

Die vorliegende Erfindung betrifft ein korrosionsfestes duktiles Gussrohr. The present invention relates to a corrosion resistant ductile iron pipe.

Technischer Hintergrund Technical background

Duktile Gussrohre finden heutzutage immer mehr Verwendung. Sie sind zwar im Grunde genommen aus Gusseisen, besitzen aber die ähnlichen Eigenschaften wie Stahl wie zum Beispiel in Sachen Härte und Elastizität, sind aber viel billiger als Stahl. Daher werden duktile Gussrohre sehr viel in Stadtkanalisationen sowie in Wasser-. Gas- oder Ölpipelines eingesetzt. Die üblichen duktilen Gussrohre lassen sich im Hinblick auf die Korrosionswiderstandfähigkeit noch etwas zu wünschen übrig. Ductile iron pipes are being used more and more today. Although they are basically made of cast iron, but have the similar properties of steel as for example in terms of hardness and elasticity, but are much cheaper than steel. Therefore, ductile iron pipes are very much used in city sewers as well as in water. Gas or oil pipelines used. The usual ductile cast iron pipes leave something to be desired in terms of corrosion resistance.

Inhalt der Erfindung Content of the invention

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, ein korrosionsfestes duktiles Gussrohr anzugeben. The present invention is therefore based on the object of specifying a corrosion-resistant ductile cast iron pipe.

Diese Aufgabe wird durch das folgende technische Konzept gelöst: Das erfindungsgemäße duktile Gussrohr umfasst einen Grundkörper, um den eine Zinkschicht angebracht ist, auf der eine Asphaltschicht aufgetragen ist. Um die Asphaltschicht ist eine Glasgewebeschicht umwickelt, auf der eine Polyurethanen-Schicht angebracht ist, die von einer Polyethylen-Schicht umgeben ist. This object is achieved by the following technical concept: The ductile iron pipe according to the invention comprises a base body, around which a zinc layer is applied, on which an asphalt layer is applied. A layer of glass fabric is wrapped around the asphalt layer, on which layer of polyurethane is placed, which is surrounded by a polyethylene layer.

Die Dicke der Zinkschicht beträgt 40–100 µm, die Dicke der Asphaltschicht 100–200 µm, die Dicke der Polyethylen-Schicht 300–350 µm. The thickness of the zinc layer is 40-100 microns, the thickness of the asphalt layer 100-200 microns, the thickness of the polyethylene layer 300-350 microns.

Ausführungsbeispiel embodiment

Im Folgenden wird anhand der Zeichnung ein Ausführungsbeispiel der vorliegenden Erfindung näher erläutert. In the following an embodiment of the present invention will be explained in more detail with reference to the drawing.

Wie 1 zeigt, umfasst das erfindungsgemäße duktile Gussrohr einen Grundkörper 1, um den eine Zinkschicht 2 angebracht ist, auf der eine Asphaltschicht 3 aufgetragen ist. Um die Asphaltschicht ist eine Glasgewebeschicht 4 umwickelt, auf der eine Polyurethanen-Schicht 5 angebracht ist, die von einer Polyethylen-Schicht 6 umgeben ist. As 1 shows, the ductile iron pipe according to the invention comprises a base body 1 to give a zinc coating 2 attached, on an asphalt layer 3 is applied. Around the asphalt layer is a glass fabric layer 4 wrapped on a polyurethane layer 5 attached is that of a polyethylene layer 6 is surrounded.

Die Dicke der Zinkschicht 2 beträgt 40–100 µm, die Dicke der Asphaltschicht 3 100–100 µm, die Dicke der Polyethylen-Schicht 6 300–350 µm. The thickness of the zinc layer 2 is 40-100 μm, the thickness of the asphalt layer 3 100-100 μm, the thickness of the polyethylene layer 6 300-350 μm.

Die vorliegende Erfindung ist nicht auf das oben dargestellte Ausführungsbeispiel beschränkt. Das oben dargestellte Ausführungsbeispiel dient nur der Veranschaulichung und hat keine einschränkende Wirkung. Weitere Ausführungsmöglichkeiten, die mit dem technischen Konzept der vorliegenden Erfindung identisch sind oder diesem gleichkommen, werden auch von den Schutzansprüchen der vorliegenden Erfindung gedeckt. The present invention is not limited to the embodiment shown above. The embodiment shown above is illustrative only and has no limiting effect. Other embodiments that are identical or equivalent to the technical concept of the present invention are also covered by the claims of the present invention.
