Description

2525th

Die Erfindung betrifft eine geschlossenporig geschäumte, als geschlitztes Rohr gefertigte Isolierschale zur Rohrisolation in einem Temperaturbereich zwischen — 160°C und +115°C, wie sie in ähnlicher Form zur Isolation von Warm- und Kaltwasserleitungen eingesetzt wird.The invention relates to a closed-cell foamed, Insulating shell manufactured as a slotted pipe for pipe insulation in a temperature range between - 160 ° C and + 115 ° C, as they are in a similar form is used for the insulation of hot and cold water pipes.

Der Hauptzweck derartiger Isolierschalen ist es, eine vorgeschriebene Wärmedämmung unabhängig vom Leistungsstand der Monteure zu erreichen und dabei vor Ort kürzeste Montagezeiten zu erzielen. Zur Lösung dieser Aufgabe wurden auf der Werkstoffseite geschäumte Kunststoffe eingeführt. Hiervon sind die geschlossenporig geschäumten Materialien wegen ihrer Wasserdampfdurchlässigkeit auch für kalte Rohrleitungen verwendbar. Sie sind dadurch wesentlich vielseitiger einsetzbar als die offenporig geschäumten Kunststoffe. Voraussetzung für eine gleichbleibende Wärmedämmung ist dabei allerdings, daß die zunächst geöffnete Isolierschale während der Montage dampfdicht verschlossen wird. Regulär versucht man das dadurch zu erreichen, daß die Stoßflächen der Isolierschalen stumpf verklebt werden (u.a. Grünzweig und Hartmann: »Porofin Isolierschalen«). Nachteilig hierbei ist, daß eine schlecht durchgeführte Verklebung zu Kondenswasserbildung innerhalb der Isolierschale führen kann, was die Wärmedämmung beeinträchtigt, und daß der zusätzliche Arbeitsgang »Verkleben« zu einer erheblichen Verminderung der Stundenleistung bei der Montage führt.The main purpose of such insulating shells is to provide a prescribed thermal insulation regardless of the To achieve the level of performance of the fitters and to achieve the shortest possible assembly times on site. To the This problem was solved by introducing foamed plastics on the material side. Of these are the closed-cell foamed materials because of their water vapor permeability also for cold pipelines usable. This makes them much more versatile than the open-pore foamed plastics. A prerequisite for consistent thermal insulation is that the first opened insulating shell is sealed vapor-tight during assembly. You try that regularly to achieve that the abutting surfaces of the insulating shells are butt glued (including Grünzweig and Hartmann: "Porofin insulating shells"). The disadvantage here is that a poorly performed Bonding can lead to the formation of condensation within the insulating shell, which affects the thermal insulation impaired, and that the additional work step "gluing" leads to a considerable reduction in the Hourly output during assembly leads.

Bei einer anderen Lösung wird die montierte Isolierschale mit einer dampfundurchlässigen Kunststoffbahn umgeben, die mechanisch geschlossen wird. Hierzu sind an die Stoßkanten der Kunststoffbahnen Leisten angeschweißt, die ineinander eingehakt werden. Nachteilig ist hierbei die unvollständige Dampfabdichtung. Die Montage ist außerdem erschwert durch das labile Verhalten der Isolierschale und der losen Umhüllung. Der Erfindung liegt die Aufgabe zugrunde, eine geschlossenporige Isolierschale zu zeigen, die auf einfachste Weise und ohne Werkzeug montiert, absolut gasdicht zu schließen ist.In another solution, the installed insulating shell is covered with a vapor-impermeable plastic sheet surrounded, which is closed mechanically. For this purpose, the edges of the plastic sheets are at the edges Welded strips that are hooked into each other. The disadvantage here is the incomplete vapor seal. Installation is also made more difficult by the unstable behavior of the insulating shell and the loose ones Wrapping. The invention is based on the object of showing a closed-cell insulating shell that has The easiest way and can be assembled without tools, can be closed absolutely gas-tight.

Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.According to the invention, this object is achieved by the characterizing features of claim 1.

In einer besonderen Ausgestaltung der Erfindung ist das geschäumte Polyolefin ein vernetzter Polyäthylenschaum. In einer zweckmäßigen Ausgestaltung ist es vorgesehen, den Gleitverschluß aus Kunststoff bei einer kontinuierlichen Isolierschalenfertigung unmittelbar auf die Isolierschale aufzuextrudieren. Zur Kennzeichnung der Rohrstränge besteht weiterhin die Möglichkeit, den Gleitverschluß farbig auszuführen.In a particular embodiment of the invention, the foamed polyolefin is a crosslinked polyethylene foam. In an expedient embodiment, it is provided that the slide lock made of plastic at a continuous insulation shell production to be extruded directly onto the insulation shell. For identification The pipe strings still have the option of color-coding the slide lock.

Die mit der Erfindung erzielbaren Vorteile bestehen vor allem darin, daß die neue Isolierschale durch einen Gleitverschluß, der aus mehreren ineinandergreifenden Dichtlippen besteht, auf einfache Weise hermetisch geschlossen werden kann und daß sie in einem Temperaturbereich von — 1600C und +115° C einsetzbar ist.The advantages attainable with the present invention consist mainly in the fact that the new insulating shell by a sliding shutter consisting of a plurality of interlocking sealing lips which can be closed hermetically in a simple manner and that it in a temperature range from - used 160 0 C and + 115 ° C is.
