Abstract

The fitting has a connecting part (10) with support sleeves (20, 20') that include a free end. An end of a pipe (50) to be connected is pushed via the free end of the support sleeves. Press sleeves (30, 30') are arranged concentric to the support sleeves. The press sleeves are three dimensionally deformable in a press molded ring (34), in order to press the pipe on the support sleeves. A passive or active transponder (40') is manipulated when exceeding a predetermined force exerted on the molded ring, so that signal transmitted by the transponder is altered.

Fittings werden als Pressfittings, Schweißfittings oder Steckfittings ausgebildet.fittings be used as press fittings, weld fittings or push fittings educated.

Pressfittings für Rohre weisen im Allgemeinen ein Verbindungsteil auf, das je nach Anwendungsfall mit mindestens einer Stützhülse versehen ist, auf die das Ende eines anzuschließenden Rohres aufgeschoben wird. Jeder Stützhülse ist eine Presshülse zugeordnet, die im Wesentlichen konzentrisch zu der Stützhülse anzuordnen ist und die zumindest in einem Verpressbereich plastisch verformbar ist, um das Rohr auf die Stützhülse zu drücken.Press fittings for pipes generally have a connecting part, depending on the application with at least one support sleeve is provided, pushed onto the end of a pipe to be connected becomes. Each support sleeve is a compression sleeve assigned, which is substantially concentric with the support sleeve is to be arranged and the plastic at least in one Verpressbereich is deformable to the pipe on the support sleeve to press.

Derartige Pressfittings sind seit langem bekannt. Ein Beispiel gibt die DE 299 07 585 U1 . Sie werden beispielsweise als T-Stück, als Winkel, als Kupplung oder als Reduktion ausgeführt, um die unterschiedlichsten Verlegungskonzepte zu realisieren.Such press fittings have long been known. An example gives the DE 299 07 585 U1 , They are designed, for example, as a T-piece, as an angle, as a coupling or as a reduction in order to realize a wide variety of installation concepts.

Schweißfittings, die zum Verschweißen mit Kunststoffrohren unterschiedlichsten Durchmessers eingesetzt werden, umfassen ein Schweißelement, oftmals eine Heizwendel, die mit elektrischem Strom beaufschlagt wird. Die EP 0 222 287 A1 beschreibt ein Elektro-Schweißfitting aus schweißbarem Kunststoff, auf dessen Innenfläche eine Heizwendel angeordnet ist. Um im Schweißbereich zuverlässig die erforderliche Anpresskraft aufzubringen, ist auf der Außenfläche des Schweißfittings eine Armierung in Form einer Wicklung oder eines Rohres angeordnet, deren thermischer Ausdehnungskoeffizient kleiner ist als der des schweißbaren Kunststoffes.Welding fittings that are used for welding with plastic pipes of various diameters include a welding element, often a heating coil, which is supplied with electric current. The EP 0 222 287 A1 describes an electric welding fitting made of weldable plastic, on the inner surface of a heating coil is arranged. In order to reliably apply the required contact pressure in the welding area, a reinforcement in the form of a winding or a tube is arranged on the outer surface of the welding fitting, whose thermal expansion coefficient is smaller than that of the weldable plastic.

Korrekt ausgeführte Verpress- oder Verschweißvorgänge sind für das sichere Funktionieren des fertigen Rohrleitungssystems wesentlich, und Maßnahmen, insbesondere eine Verpressung visuell daraufhin zu überprüfen, ob sie einwandfrei ist, sind bekannt. Beispielsweise werden mit Hilfe von speziellen Presswerkzeugen bei erfolgreicher Verpressung auf dem Verpressbereich mehrere Pressprägeringe erzeugt, die auch unter schlechten Lichtverhältnissen erkennbar sind. Dem Problem von Fehlverschweißungen ist bisher nur geräteseitig begegnet worden. Die DE 103 13 687 A1 schlägt dazu vor, vor Beginn der Schweißung den Zustand einer aufladbaren Batterie zu erfassen und die Zustandsdaten mit den relevanten Daten des zu verschweißenden Bauteils abzugleichen. Die Schweißung wird nur dann ausge führt, wenn durch den Vergleich festgestellt werden konnte, dass die Schweißung ordnungsgemäß durchgeführt und beendet werden kann. Beim Aufbau komplexer Rohrleitungssysteme kann jedoch nicht ausgeschlossen werden, dass Verpressungen oder Verschweißungen einfach vergessen werden.Correctly carried out pressing or welding operations are essential for the safe functioning of the finished pipeline system, and measures, in particular a compression visually to check whether it is faultless, are known. For example, with the help of special pressing tools with successful pressing on the grouting area, several pressing collars are produced, which are recognizable even under low light conditions. The problem of Fehlverschweißungen has been encountered only on the device side. The DE 103 13 687 A1 proposes to detect the condition of a rechargeable battery before starting the welding and to compare the condition data with the relevant data of the component to be welded. Welding will only be carried out if it has been established by comparison that the welding can be carried out and completed properly. When constructing complex piping systems, however, it can not be ruled out that forgings or welds are easily forgotten.

Steckfittings bestehen im Allgemeinen aus einem Grundkörper, der in ein Rohrende einschiebbar ist, und eine mit dem Grundkörper verbindbare Hülse, in der ein Spannring zur Fixierung des Rohres angeordnet ist, wie beispielsweise in der EP 1 183 480 B1 dargestellt ist. Es muss sichergestellt werden, dass das Rohrende korrekt in dem Ringspalt zwischen der Hülse und dem Grundkörper sitzt. Dazu sind Sichtfenster vorgesehen, so dass bei und auch nach der Montage überprüft werden kann, ob das Rohrende ordnungsgemäß im Steckverbinder fixiert ist. Auch hier sollte natürlich sichergestellt werden, dass keine Steckverbindung vergessen wird.Plug-in fittings generally consist of a base body which can be inserted into a pipe end, and a connectable to the base sleeve, in which a clamping ring is arranged for fixing the tube, such as in the EP 1 183 480 B1 is shown. It must be ensured that the pipe end sits correctly in the annular gap between the sleeve and the main body. For this purpose, viewing windows are provided so that it can be checked during and after assembly, whether the pipe end is properly fixed in the connector. Of course, it should also be ensured here that no plug connection is forgotten.

Es ist daher die Aufgabe der Erfindung, ein Fitting zur Verfügung zu stellen, bei dem ein erfolgreiches Verpressen oder Verschweißen sicher festgestellt werden kann und das vergessene Verpressungen, Verschweißungen oder Steckverbindungen praktisch ausschließt.It Therefore, the object of the invention is to provide a fitting in which a successful pressing or welding can be ascertained safely and the forgotten crimps, Virtually excludes welds or connectors.

Diese Aufgabe wird von einem Fitting nach Anspruch 1, nach Anspruch 5 oder nach Anspruch 11 gelöst. Vorteilhafte Ausgestaltungen sind Gegenstand der Unteransprüche.These The object is a fitting according to claim 1, according to claim 5 or solved according to claim 11. Advantageous embodiments are the subject of the dependent claims.

Erfindungsgemäß ist nach einem ersten Aspekt der Erfindung ein Fitting als ein Pressfitting für ein Rohr, insbesondere für ein Kunststoffrohr oder ein Metall-Kunststoff-Verbundrohr ausgebildet, das ein Verbindungsteil, welches einen Stützhülse mit einem freien Ende aufweist, über das ein Ende eines anzuschließenden Rohres aufschiebbar ist, und eine Presshülse, die im Wesentlichen konzentrisch zur Stützhülse anzuordnen ist und die zumindest in einem Verpressbereich plastisch verformbar ist, um das Rohr auf die Stützhülse zu drücken, aufweist, dadurch gekennzeichnet, dass eine Signal sendende Funk-Kommunikationseinheit in tegriert oder befestigt ist, welche beim Überschreiten einer vorbestimmten, auf den Verpressbereich ausgeübten Kraft manipuliert oder zerstört wird. Solange daher ein Empfangs- oder Lesegerät noch ein unverfälschtes Signal von irgendeiner der Funk-Kommunikationseinheiten empfängt, kann davon ausgegangen werden, dass die Verpressungen für das gesamte System nicht abgeschlossen sind. Erst wenn alle Signale verändert empfangen werden oder Signale völlig ausbleiben, sind alle Funk-Kommunikationseinheiten manipuliert oder zerstört und die Verpressungen erfolgreich abgeschlossen.According to the invention According to a first aspect of the invention, a fitting as a press fitting for a pipe, in particular for a plastic pipe or a metal-plastic composite pipe, which is a connecting part, which has a support sleeve with a free end has, over the one end of a to be connected Pipe is slidable, and a compression sleeve, which is essentially is concentric with the support sleeve to arrange and which is plastically deformable at least in one pressing region, to push the pipe onto the support sleeve, characterized in that a signal transmitting radio communication unit is integrated or attached, which when crossing a predetermined, applied to the Verpressbereich Force is manipulated or destroyed. As long as therefore one Receiving or reading device still a genuine Receives signal from any of the radio communication units, can be assumed that the crimping for the entire system is not completed. Only when all signals be received changed or signals completely fail, all radio communication units are manipulated or destroyed and the grouting completed successfully.

Vorteilhaft ist die Funk-Kommunikationseinheit in die Presshülse integriert oder an ihr befestigt, da die Verpresskraft zu allererst auf diese ausgeübt wird. Nach einer bevorzugten Ausführungsform ist die Funk-Kommunikationseinheit dabei auf der Außenseite der Presshülse vorgesehen und somit für den Benutzer sichtbar. Damit kann nach abgeschlossenem Pressvorgang die Zerstörung der Funk-Kommunikationseinheit durch den Benutzer festgestellt werden.Advantageously, the radio communication unit is integrated into the compression sleeve or attached to it, since the pressing force is exercised first of all on this. According to a preferred embodiment, the radio communication unit is provided on the outside of the compression sleeve and thus for the user visible. This can be determined by the user after completion of pressing the destruction of the radio communication unit.

Nach einer alternativen Ausgestaltung kann die Funk-Kommunikationseinheit auf der Innenseite der Presshülse oder in diese integriert vorgesehen sein. Allerdings hat dies den Nachteil, dass die in der Regel metallische Presshülse das Funksignal abschirmen würde, so dass sich Probleme wegen mangelnder Reichweite ergeben.To an alternative embodiment, the radio communication unit on the inside of the compression sleeve or integrated into it be provided. However, this has the disadvantage that usually metallic compression sleeve would shield the radio signal, so that problems arise because of lack of range.

Nach einem zweiten Aspekt der Erfindung ist das Fitting als ein Schweißfitting ausgebildet, welches ein Schweißelement enthält, das die Verbindung mit einem Rohr oder dergleichen herstellt. Beim Fitting ist wiederum eine Signal sendende Funk-Kommunikationseinheit integriert oder befestigt, welche unter Temperatureinfluss manipuliert oder zerstört wird, so dass das Signal verändert wird und die Änderung erfasst werden kann. Die Veränderung des Signals bedeutet auch, dass das Signal völlig ausbleibt.To In a second aspect of the invention, the fitting is as a weld fitting formed, which contains a welding element, which makes the connection with a pipe or the like. When fitting In turn, a signal transmitting radio communication unit is integrated or attached, which manipulated under the influence of temperature or is destroyed, so that the signal is changed and the change can be detected. The change the signal also means that the signal is completely absent.

Nach einem dritten Aspekt der Erfindung ist das Fitting als ein Steckfitting ausgebildet, das mindestens einen Steckverbinder umfasst, der einen in ein Rohrende einschiebbaren Grundkörper und eine mit dem Grundkörper verbindbare Hülse aufweist, die zwischen sich einen Ringspalt definieren, in den das Rohrende aufgenommen wird. Eine ein Signal sendende Funk-Kommunikationseinrichtung ist im Bereich des Ringspaltes vorgesehen, die beim Einstecken eines Rohres in den Ringspalt zerstört oder so manipuliert wird, dass das von der Funk-Kommunikationseinrichtung gesendete Signal verändert wird oder ausbleibt.To In a third aspect of the invention, the fitting is a plug-in fitting formed, which comprises at least one connector, the one in a pipe end retractable body and a with the base body connectable sleeve which define between them an annular gap into which the pipe end was added becomes. A radio communication device transmitting a signal is provided in the region of the annular gap, the insertion of a Tube is destroyed or manipulated in the annular gap, that the signal transmitted by the radio communication device is changed or not.

Fittings können grundsätzlich auch als kombinierte Press- und Schweißfittings ausgebildet werden, wobei beispielsweise die Schweißverbindung zu einem Rohr bereits werksseitig hergestellt wird und die weiteren Rohranschlüsse vor Ort mittels Pressverbindungen vorgenommen werden.fittings can in principle also be used as a combined press and weld fittings are formed, for example the welded connection to a pipe already at the factory is produced and the other pipe connections on site be made by means of press connections.

Auch Kombinationen von Press- und Steckfittings, von Steck- und Schweißfittings und von Press-, Schweiß- und Steckfittings sind denkbar.Also Combinations of press and plug fittings, plug and welding fittings and of press, welding and plug fittings are conceivable.

Die Funk-Kommunikationseinheit ist vorzugsweise als passiver Transponder ausgestaltet, der zusammen mit einem entsprechenden Lesegerät ein RFID-System bildet. Aktive Transponder als Funk-Kommunikationseinheit werden ebenfalls in Betracht gezogen. Der Transponder kann zusätzlich Daten enthalten, beispielsweise über den Typ des Fittings, seine Größe, über das geeignete Presswerkzeug bzw. Information über den Schweißvorgang und dergleichen.The Radio communication unit is preferably as a passive transponder designed, which together with a corresponding reader RFID system forms. Active transponder as radio communication unit are also considered. The transponder can also receive data included, for example, on the type of fitting, his Size, via the appropriate pressing tool or information about the welding process and the like.

Im Folgenden soll die Erfindung anhand der beigefügten Zeichnung näher erläutert werden. Dabei zeigt:in the Below, the invention with reference to the accompanying drawings be explained in more detail. Showing:

1 ein Pressfitting in der Gestalt eines T-Stückes, teilweise in Explosionsdarstellung und mit Detailansichten (a), (b) einiger Komponenten; 1 a press fitting in the form of a tee, partially exploded and with detailed views (a), (b) of some components;

2 eine Schnittansicht eines Schweißfittings; und 2 a sectional view of a weld fitting; and

3 ein Steckfitting in der Gestalt eines T-Stückes, teilweise aufgeschnitten. 3 a plug-in fitting in the shape of a tee, partially cut open.

Das in der 1 gezeigte Pressfitting besteht aus einem Verbindungsteil 10, das bei der dargestellten Ausführungsform drei Stützhülsen aufweist, von denen lediglich zwei 20, 20' dargestellt sind. Jede Stützhülse, 20, 20' weist einen radial umlaufenden doppelten O-Ring 22, 22' zur Erhöhung der Montagesicherung auf. Über das freie Ende jeder Stützhülse 20, 20' kann ein anzuschließendes Rohr 50 aufgeschoben werden.That in the 1 shown press fitting consists of a connecting part 10 which in the illustrated embodiment comprises three support sleeves, of which only two 20 . 20 ' are shown. Each support sleeve, 20 . 20 ' has a radially encircling double O-ring 22 . 22 ' to increase the mounting protection. Over the free end of each support sleeve 20 . 20 ' can be a pipe to be connected 50 be deferred.

Ein üblicherweise verwendetes Rohr 50, im Teilbild (a) schematisch dargestellt, ist beispielsweise als Metall-Kunststoff-Verbundrohr aufgebaut und besteht aus einem stumpf verschweißten Aluminiumrohr 54, das mit einem hochtemperaturbeständigen Inliner 56 ausgekleidet ist. Das Aluminiumrohr 54 ist außen von einem Schutzmantel 52 aus hochdichtem Polyethylen (PE-HD), vernetztem Polyethylen (PEX) oder Polyethylen mit erhöhter Temperaturfestigkeit (PE-RT) umgeben. Die Rohrenden werden in der Regel vorbereitenden Maßnahmen, wie Entgraten, Kalibrieren, Anfasen, unterworfen.A commonly used pipe 50 , shown schematically in part (a), is constructed, for example, as a metal-plastic composite pipe and consists of a butt welded aluminum tube 54 that with a high temperature resistant inliner 56 is lined. The aluminum tube 54 is outside of a protective jacket 52 made of high-density polyethylene (PE-HD), cross-linked polyethylene (PEX) or polyethylene with increased temperature resistance (PE-RT). The pipe ends are usually subjected to preparatory measures, such as deburring, calibrating, chamfering.

Bevor das anzuschließende Rohr 50 auf eine Stützhülse 20, 20' aufgeschoben wird, wird eine Presshülse 30, 30' auf das Rohr 50 gesetzt. Die unverpresste Presshülse 30, im Teilbild (b) gezeigt, ist als beidseitig offener Hohlzylinder dargestellt, der üblicherweise aus Edelstahl besteht. Bei modernen Systemen ist die Presshülse auch vormontiert. Am offenen Ende, das nach der Montage zum Verbindungsteil 10 weist, ist eine Stirndichtung 36, die gleichzeitig das Rohr 50 und das Pressfitting 10 entkoppelt, als Spritzwasserschutz während des Baustellenbetriebs vorgesehen. In vielen Fällen weist die Presshülse 30 auch ein Mittel zur optischen Kontrolle der Einschubtiefe des Rohres 50 auf.Before the pipe to be connected 50 on a support sleeve 20 . 20 ' is pushed, is a compression sleeve 30 . 30 ' on the pipe 50 set. The unpressed compression sleeve 30 , shown in part (b), is shown as open on both sides hollow cylinder, which is usually made of stainless steel. In modern systems, the compression sleeve is also pre-assembled. At the open end, after assembly to the connecting part 10 points is a front seal 36 , at the same time the pipe 50 and the press fitting 10 decoupled, intended as splash protection during construction site operation. In many cases, the compression sleeve 30 also a means for optical control of the insertion depth of the tube 50 on.

Die Presshülse 30 umfasst weiterhin eine Funk-Kommunikationseinheit 40, beispielsweise in Form eines passiven oder aktiven Transponders, die ein Signal sendet. Transponder sind in vielen Ausgestaltungen auf dem Markt, beispielsweise als Folienstreifen, der eine gewisse Unempfindlichkeit gegenüber dem manchmal rauen Betrieb auf der Baustelle zeigt. Der Transponder 40 ist bei der dargestellten Ausführungsform auf der Außenseite 32 der Presshülse 30 angebracht, beispielsweise durch Verkleben. Der Transponder 40 enthält zweckmäßigerweise Daten über das Pressfitting, beispielsweise den Durchmesser, weiterhin Angaben über das zu verwendende Presswerkzeug. Diese Daten können vor dem Verpressvorgang durch ein entsprechendes Lesegerät ausgelesen werden, so dass der Verpressvorgang ohne Gefahr von Fehlern vorbereitet werden kann.The compression sleeve 30 further comprises a radio communication unit 40 , for example in the form of a passive or active transponder, which sends a signal. Transponders are in many designs on the market, for example as a foil strip, which shows a certain insensitivity to the sometimes rough operation on the construction site. The transponder 40 is at the illustrated Embodiment on the outside 32 the compression sleeve 30 attached, for example by gluing. The transponder 40 conveniently contains data on the press fitting, such as the diameter, further information about the pressing tool to be used. These data can be read by a corresponding reader before the pressing process, so that the pressing process can be prepared without risk of errors.

Nach Auswahl des korrekten Presswerkzeuges wird dann auf die Presshülse 30 eine Presskraft ausgeübt, die das Rohr 50 auf die Stützhülse 20 drückt. In Abhängigkeit von den am Presswerkzeug verfügbaren Pressbacken entstehen bei der hier dargestellten Form der Verpressung drei gleichmäßige Pressprägeringe 34, die auch bei schlechten Lichtverhältnissen erkennbar sind. Einer der Pressprägeringe durchquert den Transponder 40 und manipuliert oder zerstört diesen. Der Transponder 40 sendet daher ein verändertes Signal oder kann gar nicht mehr mit dem Lesegerät kommunizieren. Sobald alle Presshülsen 30 an einer Baustelle verpresst sind, empfängt das Lesegerät ein verändertes Signal oder überhaupt kein Signal mehr. Dies bedeutet, dass alle Pressfittings korrekt verpresst sind.After selecting the correct pressing tool is then on the compression sleeve 30 a pressing force is exerted on the pipe 50 on the support sleeve 20 suppressed. Depending on the press jaws available on the press tool, three uniform press spring rings are produced in the case of the pressing shown here 34 that are recognizable even in low light conditions. One of the press spring rings passes through the transponder 40 and manipulate or destroy it. The transponder 40 therefore sends a modified signal or can no longer communicate with the reader. Once all the ferrules 30 are pressed at a construction site, the reader receives a changed signal or no signal at all. This means that all pressfittings are correctly pressed.

Es versteht sich, dass beim Verpressvorgang nicht notwendigerweise Pressprägeringe erzeugt werden müssen, um die Funk-Kommunikationseinrichtung zu zerstören oder so zu manipulieren, dass das gesendete Signal geändert wird, es muss lediglich ein bestimmter Kraftwert überschritten werden, der auf die Funk-Kommunikationseinrichtung wirkt.It It is understood that during the pressing process not necessarily Press suspension rings must be produced to the Radio communication device to destroy or so manipulate that the transmitted signal is changed, it only has to exceed a certain force value which acts on the radio communication device.

2 zeigt eine Schnittansicht eines Schweißfittings, das beispielsweise zur Verbindung zweier Rohre eingesetzt werden kann. Das Schweißfitting besteht aus einer zylindrischen Muffe 100, in deren Innenfläche Heizdrahtwicklungen 110, 120 vorzugsweise zur Muffeninnenseite freiliegend eingebracht sind. Die Heizdrahtwicklungen 110 und 120 definieren jeweils einen Schweißbereich. Obwohl getrennte Heizdrahtwicklungen vorgesehen sein können, ist bei der dargestellten Ausführungsform eine durchgängige Wicklung vorgesehen, mit der beide Fittingseiten gleichzeitig zu schweißen sind. Die Beaufschlagung mit Strom erfolgt über Anschlussstifte 115 bzw. 125. Ein radial nach Innen weisender, umlaufender Vorsprung 130 dient als Anschlag für die in die Muffe 100 einzuführenden Rohrenden. Jedem Schweißbereich ist ein Transponder 40, 40' zugeordnet, der in die Muffe 100 eingearbeitet oder auf ihrer Außenseite angeordnet ist. Die in 2 dargestellte Lage des Transponders 40 ist lediglich beispielhaft, andere Anordnungen sind möglich. Der Transponder 40, 40' enthält Informationen über das Fitting und über den Schweißvorgang, die an ein Schweißgerät gegeben werden können, so dass der Schweißvorgang an sich korrekt durchgeführt werden kann. Beim Schweißvorgang wird dann der Transponder 40, 40' unter Temperatureinfluss manipuliert oder zerstört, so dass wiederum das von ihm gesendete Signal verändert wird oder sogar ganz ausbleibt. 2 shows a sectional view of a welding fitting, which can be used for example for connecting two pipes. The welding fitting consists of a cylindrical sleeve 100 , in whose inner surface Heizdrahtwicklungen 110 . 120 are preferably introduced exposed to the socket inside. The heating wire windings 110 and 120 each define a welding area. Although separate Heizdrahtwicklungen can be provided, a continuous winding is provided in the illustrated embodiment, with the two fitting sides are to be welded simultaneously. The application of electricity via pins 115 respectively. 125 , A radially inwardly facing, circumferential projection 130 serves as a stop for the in the sleeve 100 to be introduced pipe ends. Each welding area is a transponder 40 . 40 ' assigned to the sleeve 100 incorporated or arranged on its outside. In the 2 shown position of the transponder 40 is merely exemplary, other arrangements are possible. The transponder 40 . 40 ' Contains information about the fitting and the welding process that can be given to a welding machine so that the welding process itself can be carried out correctly. The transponder then becomes the welding process 40 . 40 ' manipulated or destroyed under the influence of temperature, so that in turn the signal transmitted by him is changed or even completely absent.

3 zeigt ein Steckfitting in der Gestalt eines T-Stückes, das einen T-förmigen Grundkörper 150 aufweist, auf den die Enden von Rohren 50, 50', 50'' aufzustecken sind. Dabei ist der Grundkörper 150 jeweils von Hülsen, z. B. 160, umgeben, wobei zwischen Grundkörper 150 und Hülse 160 ein Ringspalt gebildet ist, in dem das Ende des Rohres 50 einzuschieben ist, wobei es von Haltekrallen 165 am Herausrutschen gehindert wird. Auf dem Grundkörper 150 ist weiterhin ein Dichtelement 170 fixiert. An jeder Hülse sind Sichtfenster, z. B. 180, 180', 180'' für eine optische Kontrolle des eingeschobenen Rohres vorgesehen. Mögliche Lagen für einen Transponder 40, 40', 40'' sind beispielhaft eingezeichnet. So kann sich ein Transponder 40 in der Nähe der Anlagestelle für das Rohrende befinden. In dieser Lage ist eine Zerstörung des Transponders 40 unwahrscheinlich, das eingeschobene Rohr 50 jedoch, insbesondere wenn es sich um ein Mehrschichtrohr mit einer Lage aus Aluminium oder um ein Rohr mit eingelegtem Edelstahlgeflecht handelt, wird das Signal verändern. Ein Transponder 40', der am Grundkörper in der Nähe des Anlagebereichs oder an der Innenseite der Hülse in der Nähe des Anlagebereichs angeordnet ist, wird bei entsprechender Auslegung durch das sich vorbeibewegende Rohr 50 zerstört. Ein Transponder 40'' kann auch auf der Außenseite der Hülse unterhalb eines Sichtfensters 180'' oder zwischen zwei umfangsmäßig benachbarten Sichtfenstern (nicht dargestellt) angeordnet sein. Jedenfalls wird der Transponder 40, 40', 40'' erst dann ein verändertes Signal aussenden, wenn das Rohrende korrekt im Fitting sitzt. Jedenfalls wird ausgeschlossen, das eine Steckverbindung vergessen wird. 3 shows a plug-in fitting in the form of a tee, which is a T-shaped body 150 on which the ends of pipes 50 . 50 ' . 50 '' to be stuck on. Here is the main body 150 each of pods, z. B. 160 , surrounded, being between basic body 150 and sleeve 160 an annular gap is formed in which the end of the pipe 50 it is to be inserted, it by holding claws 165 is prevented from slipping out. On the main body 150 is still a sealing element 170 fixed. At each sleeve viewing window, z. B. 180 . 180 ' . 180 '' provided for a visual inspection of the inserted tube. Possible positions for a transponder 40 . 40 ' . 40 '' are shown by way of example. So can a transponder 40 near the pipe end fitting point. In this situation is a destruction of the transponder 40 unlikely, the tube inserted 50 however, especially if it is a multilayer tube with a layer of aluminum or a tube with stainless steel braid inserted, the signal will change. A transponder 40 ' , which is arranged on the base body near the contact area or on the inside of the sleeve in the vicinity of the contact area, with appropriate design by the passing by tube 50 destroyed. A transponder 40 '' can also be on the outside of the sleeve below a viewing window 180 '' or between two circumferentially adjacent viewing windows (not shown). Anyway, the transponder 40 . 40 ' . 40 '' only send a modified signal when the pipe end is correctly seated in the fitting. In any case, it is excluded that a plug connection is forgotten.

Die Erfindung umfasst auch kombinierte Fittings, bei denen beispielsweise ein Teil der Rohrverbindungen verschweißt, ein anderer verpresst wird. Außerdem können die Fittings spezielle Steckanschlüsse aufweisen, beispielsweise Push-Fit-Verbindungen.The The invention also includes combined fittings in which, for example one part of the pipe joints welded, another is pressed. In addition, the fittings can special Have plug-in connections, such as push-fit connections.

Es liegt weiterhin im Rahmen der Erfindung, die Fittings an andere Bauteile als an Rohre anzubinden bzw. mit diesen zu verpressen, verschweißen oder eine Steckverbindung herzustellen.It is still within the scope of the invention, the fittings to others To bond components to tubes or to press them together, weld or make a plug connection.

Die in der vorstehenden Beschreibung, in der Zeichnung sowie in den Ansprüchen offenbarten Merkmale der Erfindung können sowohl einzeln als auch in beliebiger Kombination für die Verwirklichung der Erfindung wesentlich sein.The in the above description, in the drawing and in the Claims disclosed features of the invention can both individually and in any combination for the To be essential to the realization of the invention.
