Description
Die Erfindung betrifft eine Verbindung für mit Metalloder Kunststoff od. dgl. versehene Auskleidungen von insbesondere Hochdruckrohrleitungen. Es ist bereits -eine Verbindung bekannt für Rohre mit :einer gegen chemische Einflüsse, Hitze u. dgl. widerstandsfähigen Auskleidung, wobei sich ein in radialer Richtung verjüngender Dichbungskörp er gegen die umgebördelten plattler;ten, Rohrenden legt. Diese Anordnung genügt jedoch nicht für Hiochdruckrohrleitungen, da sich Teile sowohl der Dichtung als auch der Plattierung unter dem Druck aus der. Rohrleitung herausquetschen.The invention relates to a connection for metal or plastic or the like. Linings, in particular, provided for high-pressure pipelines. It is already-a connection known for pipes with: one against chemical influences, Heat and similar resistant lining, with a radial direction he places the tapered sealing body against the flanged flat ends of the pipe. However, this arrangement is not sufficient for high pressure pipelines, since parts are both the seal as well as the plating under the pressure from the. Squeeze out the pipeline.
Die Erfindung vermeidet diesen Nachbeil dadurch, daß der Berührungsstoß der Plattierungen beider Rohre abgedeckt ist. Die Erfindung wird beispielsweise durch die Abb. i bis 6 gekennzeichnet.The invention avoids this disadvantage in that the contact shock the cladding of both tubes is covered. The invention is for example marked by fig. i to 6.
Nach Abb. i handelt @es sich um eine Flanschverbindung (Flansche s.. Abb. 5). Die Rohrendena und b sind verstärkt. Das Rohrende a hat über der Plattierung deinen vorstehenden Teil d, welcher über Beinen @entsprechend abgesetzten Teile des Rohrendes b übergreift. Hierdurch ist der Gefiahrenpunke x beseitigt, @d. h. weder die Plattierung C noch die Dichtung f kann durch den Spalt g durchgedrückt werden.According to Fig. I, it is a flange connection (flanges see .. Fig. 5). The pipe ends a and b are reinforced. The pipe end has a above the cladding your protruding part d, which is about legs @ correspondingly separated parts of the pipe end b overlaps. This eliminates the danger point x, @d. H. neither the cladding C nor the gasket f can be pushed through the gap g will.
Das gleiche gilt für Abb.2. Der Unterschied liegt nur rein äußerlich darin, daß anstatt der Flanschverbindung es _sich hier um eine, Schweißverbindung handelt. Während nach Abb. i die Fuge g erforderlich ist, zum festen und sicheren Anziehen der Dichtung f, wird die Schweiße h ge- legt, nachdem die Dichtung fest angezogen. ist.The same goes for Fig.2. The only external difference is that instead of the flange connection, it is a welded connection. While, according to Fig. I, the joint g is required to tighten the gasket f firmly and securely, the weld h is made after the gasket is firmly tightened. is.
Nach der Abb. 3 ;greift :ein über die Plattierung a' vorstehender Steg i des einen Rohrendes ,a in eine entsprechende Nut des anderen Rohrendes b ein.According to Fig. 3; engages: a protruding over the plating a ' Web i of one end of the pipe, a in a corresponding groove of the other end of the pipe b a.
Für Abb. q. gilt das gleiche wie für Abb. 2. Nach Abt. 5 besitzen beide Rohrenden eine gleichlaufende Nut i, in welche ein Abdeckring m passend eingelegt ist. Für die Abb. 6 gilt das gleiche wie für die Abb. q. und z. Bei diesen Verbindungen kommt es in der Hauptsache darauf an, vor Durchführung der Schweißung die Dichtung -fest und sicher anziehen zu können. Wichtig und vorteilhaft ist hierbei, daß der Schmelzpgrozeß beim Schweißgen niemals die Rohrauskleidung und Dichtung x mit anfassen -und abschmelzen 'kann.For Fig.q. The same applies as for Fig. 2. According to Section 5, possess Both pipe ends have a concurrent groove i, into which a cover ring m is inserted is. The same applies to Fig. 6 as to Fig. Q. and Z. With these connections the main thing is to make the seal before welding - to be able to put them on firmly and safely. It is important and advantageous that the When welding, never touch the pipe lining and seal x when welding -and melt away '.
Die Ausbildung der Rohrenden kann hierbei nach dein bereits gemachten Vorschlag so !erfolgen, daß die Wandung des Kemrolhres an den Enden zuerst verdünnt wird und danach die Enden zum Anliegen an den anderen Teil gebracht werden. Hiernach werden die Fugen, wie .durch y angedeutet, wieder geschlossen.The formation of the pipe ends can be done according to what you have already done Proposal made so that the wall of the core tube is first thinned at the ends and then the ends are brought to rest against the other part. After that the joints, as indicated by y, are closed again.
Nach denn Abb. 7 bis i o ist unmittelbar die Sehweiße lt als Abdeckung und D0.chtung und Plattierungsstoß vorgesehen. Zur Unterstützungiderselben werden die En-denn aus deni Vollen h'erausged:t. Beim; festem. Anziehen der Dichtung werden dieselben in der Wurzel der Schweißnaht mitverschweißt. Die Abb.8 bis 9 zeigen geschweißte Verbindungen, wobei, die Ringkreuze o aus den gebärdelten verdünnten Enden gebildet werden. Nach der Abb. i o dient ein mit Schlitzen p versehener Gewindenippel g, wie nach Abt. 8, zunächst zum festen und dichten Zusammenfügen der Rohrenden auf die überdeckte Dichtung sowie die Plattierungsendkanten. Nach der Abb. i o wird der Gewindenippel g in der Mitte noch durch einen Steg r zusammengehalten. Die Vorteile gegenüber den bekannten liegen in reiner absolut festen und sicheren Lage der Dichtungs- und Plattie,rungsenden.According to Fig. 7 to i o, the vision whiteness is immediately used as a cover and D0. caution and plating joint provided. Be in support of the same the end then from the full h'erausged: t. At the; solid. Tighten the seal the same welded in the root of the weld seam. Figures 8 to 9 show welded Connections, whereby, the ring crosses o formed from the tinkered thinned ends will. According to Fig. I o, a threaded nipple g provided with slots p serves, as in Section 8, initially for the firm and tight joining of the pipe ends the covered gasket as well as the plating end edges. According to Fig. I o will the threaded nipple g is still held together in the middle by a web r. The advantages compared to the known are in a pure, absolutely solid and safe position of the sealing and plating ends.
