Description

Mit einem Mantel aus einem Werkstoff größerer Festigkeit gepanzerte Rohre, Gefäße, Formstücke u. dgl. Hohlkörper aus Kunststoff Die Erfindung bezieht sich auf Hohlkörper aus thermoplastischen Kunststoffen, wie Rohre, Gefäße, Formstücke u. dgl., die mit einem Mantel aus einem Werkstoff höherer Festigkeit, wie z.B.Metall, gepanzert sind.Armored with a jacket made of a material of greater strength Pipes, vessels, shaped pieces and the like. Hollow bodies made of plastic on hollow bodies made of thermoplastics, such as pipes, vessels, fittings and the like, which are covered with a jacket made of a material of higher strength, such as metal, are armored.

Gemäß einem älteren Vorschlag wird bei der Herstellung solcher Hohlkörper in der Weise vorgegangen, daß das Kunststoff-Fonnteil in den beiden Achsen seiner Oberflächenebene durch die Panzerung so auf Druckspannung gebracht ist, daß auch bei der tiefsten Gebrauchstemperatur, die z.B. bei Hartpolyvinylchlorid etwa 200 C beträgt, und/oder bei innerem Uberdruck immer noch ein Rest Druckvorspannung in diesen beiden Achsenrichtungen des Kunststoff-Formteiles vorhanden ist, so daß dieses bei allen vorkommenden Betriebsbedingungen praktisch frei von Zugspannungen bleibt. According to an older proposal, in the production of such hollow bodies proceeded in such a way that the plastic Fonnteil in the two axes of his The surface plane is brought to compressive stress by the armor so that at the lowest service temperature, which is around 200 for rigid polyvinyl chloride, for example C, and / or with internal overpressure there is still a residual pressure prestress in these two axis directions of the plastic molding is present, so that this remains practically free of tensile stress under all operating conditions.

Die Erzeugung der Druckvorspannung kann z. B. durch mechanische Verformung des Metallpanzers oder des Kunststoff-Formteiles oder beide Teile bewirkt werden, so z.B. durch Ziehen, Recken, Stauchen, Drücken, Walzen od. dgl. The generation of the compressive bias can, for. B. by mechanical deformation the metal armor or the plastic molded part or both parts are effected, e.g. by pulling, stretching, compressing, pressing, rolling or the like.

Eine hesonders zweckmäßige Arbeitsweise zur Erzeugung der Druckvorspannung wird durch die vorliegende Erfindung offenbart. Sie besteht darin, daß der Innendurchmesser des Panzerrohres und der Außendurchmesser des Kunststoffrohres, Gefäßes oder Formstückes unter Berücksichtigung der verschiedenen Ausdehnungskoeffizienten der beiden Werkstoffe so aufeinander abgestimmt sind, daß das vorteilhaft unterkiihlte Kunststoffteil in dem gegebenenfalls erwärmten Metallpanzer mit geringem Spiel Aufnahme findet und beim Ausgleich der Temperaturen durch die verschiedenen Ausdehnungskoeffizienten die gewünschte Druckvorspannung im Kunststoff-Formteil erreicht wird. Diese Druckvorspannung entsteht also durch ein Schrumpfvorgang. A particularly useful way of working to generate the pressure bias is disclosed by the present invention. It consists in that the inner diameter of the armored pipe and the outer diameter of the plastic pipe, vessel or shaped piece taking into account the different expansion coefficients of the two materials are coordinated so that the advantageously undercooled plastic part in the possibly heated metal armor with little clearance and when balancing the temperatures through the various expansion coefficients the desired compressive prestress is achieved in the plastic molded part. This compressive bias thus arises from a shrinking process.
