Description

Außer der gewöhnlichen Dichtung der Rohrverbindungen durch Verstreichen der Muffen mit Teer und Verstemmen derselben mit Gußblei oder Bleiwolle sind schon besondere Dichtungsmuffen und -kappen aus Metall bekannt, die die Verbindungsstelle mit einem Hohlraum umgeben, der mit einer Teerpechmischung ausgegossen ist. Diese Dichtungsmuffen haben den Nachteil, daß sie ίο 2U teuer sind, und da die Metallmuffe im Erdreich einer Zerstörung durch Rostbildung ausgesetzt ist, benötigt sie einer besonderen Isolierung. Diese Isolierung besteht in den meisten Fällen, wenn sie wirksam sein soll, aus einer Jutewickel, wobei die Umwickelung, um keine nicht isolierten Stellen in der Leitung zu erhalten, bis über die Isolierung der Rohrenden übergreifen muß. Diese besondere Isolierung macht die bekannte Dichtungsmuffe unwirtschaftlich.Besides the usual sealing of the pipe connections by passing the Sleeves with tar and caulking with cast lead or lead wool are special Sealing sleeves and caps made of metal known, which surround the connection point with a cavity with a Tar pitch mixture is poured out. These sealing sleeves have the disadvantage that they ίο 2U are expensive, and since the metal sleeve in the Soil is exposed to destruction through rust formation, it needs a special one Insulation. This isolation exists in most cases if it is to be effective, from a jute wrap, the wrapping to avoid any uninsulated places in the pipe to get up to reach over the insulation of the pipe ends. This particular one Insulation makes the known sealing sleeve uneconomical.

Das Verfahren nach der Erfindung zeigt eine Abdichtung und Isolierung von Rohrverbindungen, das diese Nachteile in einfachster Weise behebt, indem eine aus bitu- »5 minöser Masse oder anderem dichtenden und isolierenden Material hergestellte elastische Negativform der äußeren Abwickelung der Rohrverbindung als Muffe um dieselbe gelegt wird, wobei die Muffe durch eine Blei-, Papp- oder andere geeignete Einlage verstärkt und verdichtet ist. Hierbei übergreift die elastische Muffe die Rohrenden bis über ihre Isolierung heraus, so daß in der ganzen Leitung keine unisolierte Stelle mehr ist. Die Endkanten der um das Rohr gelegten Formplatte werden zu einer Muffe und die Enden der Muffe mit den Rohren durch Hitze vereinigt. Da die Dichtungsmuffe aus isolierendem Material besteht, ist nunmehr eine besondere Isolierung der Rohrverbindungsstelle überflüssig.The method according to the invention shows a sealing and insulation of pipe connections, which eliminates these disadvantages in the simplest way by using a bituminous mass or other sealing and insulating material produced elastic negative form of the outer development of the Pipe connection is placed around the same as a sleeve, the sleeve being secured by a lead, cardboard or other suitable insert is reinforced and compacted. This overlaps the elastic Socket the pipe ends up over their insulation, so that in the whole pipe is no longer an uninsulated place. The end edges of the mold plate placed around the pipe are combined into a socket and the ends of the socket with the pipes by means of heat. Since the sealing sleeve is made of insulating material, it is now a special one No need to isolate the pipe joint.

In der Zeichnung ist ein Ausführungsbeispiel nach dem Verfahren dargestellt, und zwar zeigtIn the drawing, an embodiment is shown according to the method, and although shows

Abb. 3 eine schaubildliche Ansicht der Dichtungs- und Isolierplatte.Fig. 3 is a perspective view of the sealing and insulating plate.

Es bedeutet α die der äußeren Abwickelung der Rohrverbindung entsprechend geformte elastische Platte aus bituminöser Masse o. dgl. Material, die nach Abb. 1 zu einer Muffe um die Rohrverbindung gelegt und deren Enden an der Stelle c durch Hitze dicht verbunden sind. An den Stellen d ist die Muffe mit den Rohrenden ebenfalls durch Hitze fest verbunden. Die Muffe α überragt beiderseitig die Rohrisolierung e, so daß die ganze Rohrleitung keine unisolierte Stelle mehr aufweist. Die Verbindung c kann zweckentsprechend stumpf oder überlappt hergestellt werden. Die Bleieinlage b hat den Zweck, die Muffe zu verstärken und abzudichten, damit bei Gasleitungen das durch die Rohrverbindung austretende Gas nicht entweichen kann.It means α the elastic plate made of bituminous compound or similar material, shaped according to the outer unwinding of the pipe connection, which according to Fig. 1 is placed around the pipe connection to form a sleeve and the ends of which are tightly connected by heat at point c. At the points d , the sleeve is also firmly connected to the pipe ends by means of heat. The sleeve α projects beyond the pipe insulation e on both sides, so that the entire pipeline no longer has an uninsulated point. The connection c can be produced butt or overlapped as appropriate. The purpose of the lead insert b is to reinforce and seal the socket so that the gas escaping through the pipe connection cannot escape in gas lines.
