Description

Verfahren zur Erhöhung der Festigkeit von Hohlkörpern durch Umwickeln Es ist bekannt, Hohlkörper verschiedener Art, z. B. Druckgefäße, zur Erhöhung ihrer Festigkeit zu umwickeln, z. B. mit Draht, Bandeisen o. dgl. Die angestrebte Erhöhung der Festigkeit wird dabei nur dann e=eicht, wenn es gelingt, den herumgewickelten Körper, z. B. Draht, wirklich zum Mittragen zu bringen. Dies wird in bekannter Weise dadurch erreicht, daß man während des. Umwickelns einen genügend großen Temperaturunterschied zwischen dem zu umwickelnden Hohlkörper und dem Umwicklungsmittel herstellt. Beim. Aufhören des Temperaturunterschiedes ergibt sich :dann :ein gegenseitiges festes Anliegen zwischen den beiden von selbst.Process for increasing the strength of hollow bodies by wrapping them It is known to use hollow bodies of various types, e.g. B. pressure vessels, to increase their To wrap strength, e.g. B. with wire, iron band o. The like. The desired increase the strength is only then calibrated if it succeeds in the wrapped around Body, e.g. B. wire, really to be carried along. This is done in a well known manner achieved by having a sufficiently large temperature difference during the wrapping between the hollow body to be wrapped and the wrapping means. At the. The cessation of the temperature difference results: then: a mutual solidity Concerns between the two of themselves.

Es. ist bereits bekannt, den exforderlichen Temperaturunterschied dadurch herzustellen, daß man den herumzuwickelnden Körper erhitzt und ihn in erhitztem Zustande um den Hohlkörper, der auf gewöhnlicher Temperatur belassen wird, herumwickelt.It. is already known the required temperature difference by heating the body to be wrapped and placing it in heated Condition wrapped around the hollow body, which is left at ordinary temperature.

Da die Erhaltung der erhöhten UM peratur bei dem herumzuwickelnden Körper während des Herumwickelns uald auch das Herumwickeln bei erhöhter Temperatur selbst mit erheblichen Schwierigkeiten verbunden ist, wird gemäß der Erfindung der erforderliche Temperaturunterschied dadurch erzeugt, daß man den Hohlkörper während des Umwickelns abkühlt und den herumzuwickehudlen Körper auf gewöhnlicher Temperatur beläßt. Der Hohlkörper dehnt sich dann biei wiederkehrender normaler Temperatur aus dem zusammengezogenen Zustande in :der Abkühlung in die durch die Umwicklung entstandene Umhüllung hinein wieder aus. Dadurch ergibt sich sodann, wenn zwischen Umwicklung und 1-Iohlkörper wieder Tempieraturgleichheit herrscht, ein enges und festes Antieggen der Umwicklung an den Hohlkörper.Because the preservation of the increased UM temperature in the case of the wrapping Body during wrapping and wrapping at elevated temperature itself is associated with considerable difficulties, is according to the invention of required temperature difference generated by the fact that the hollow body during wrapping cools and the wrapped body at ordinary temperature leaves. The hollow body then expands at a returning normal temperature from the contracted state in: the cooling into the one through the wrapping resulting casing back in again. This then results when between Wrapping and 1-hollow body again the same temperature prevails, a tight and firm antieggen of the wrapping to the hollow body.

Als Abkühlungsmittel für den Hohlkörper kann man flüssige Luft, . Kohlensäure, Trockeneis o.:d:gl. benutzen.As a cooling means for the hollow body can be liquid air. Carbon dioxide, dry ice, etc. use.
