Titel: Rohrelement aus Edelstahl zum Erstellen von Schornsteinen sowie von Abgas- und AbdampfleitungenTitle: Pipe element made of stainless steel for the construction of chimneys as well as exhaust gas and steam pipes

Die Erfindung betrifft Rohrelemente aus Edelstahl zum Erstellen von doppelwandigen Schornsteinen sowie von ein- und doppelwandigen Abgas- und Abdampfleitungen in Elementbauweise, deren Enden Kupplungsteile einer Rohrkupplung bilden, wobei das eine Ende der Rohrelemente als Kupplungsmuffe und das andere Ende der Rohrelemente als Einsteckende ausgebildet ist.The invention relates to pipe elements made of stainless steel for the construction of double-walled chimneys as well as single- and double-walled exhaust gas and exhaust steam pipes in modular construction, the ends of which form coupling parts of a pipe coupling, whereby one end of the pipe elements is designed as a coupling sleeve and the other end of the pipe elements is designed as a spigot end.

Die gesetzlichen Umweltschutzvorschriften, die den zulässigen Ausstoß von Schadstoffen, insbesondere von Kohlendioxid und Schwefel, in die freie Atmosphäre durch mit Kohle, Gas und Mineralöl betriebene Brennanlagen auf ein Minimum begrenzen, haben zur Entwicklung von neuen Verbrennungstechniken und entsprechenden Brennaggregaten geführt. Die mit der Brennwerttechnik entwickelten, vorzugsweise mit Gas und Öl betriebenen Brennwertkessel erbringen durch die teilweise Nutzung der Kondensationswärme des bei der Verbrennung gebildeten Wasserdampfes und durch die fast vollständige Ausschöpfung der fühlbaren Wärme, d.h. der herkömmlichen Abgasverluste, einen erheblichen Energiegewinn gegenüber den konventionellen Heizkesseln. Die mit der Brennwerttechnik betriebene Nutzung der Abgaswärme führt zu einer Reduzierung der Abgastemperatüren auf bis zu 40° C, die im Vergleich mit den bei 160 - 180° C liegenden Abgastemperaturen herkömmlicher Heizkessel wesentlich niedriger sind. Mit der Unterschreitung des Taupunktbereiches bei den Abgasen von Brennwertkesseln tritt das Problem der verstärkten Kondensatbildung auf. In den unter überdruck stehenden Abgasleitungen von mit Kohle und öl betriebenen Brennwert-Heiz- und Verbrennungsanlagen fällt schweflige Säure an, die eine verstärkte Korrosionsbeanspruchung der Abgasleitungen bedingt.The legal environmental protection regulations, which limit the permissible emission of pollutants, in particular carbon dioxide and sulphur, into the atmosphere by combustion systems running on coal, gas and mineral oil to a minimum, have led to the development of new combustion technologies and corresponding combustion units. The condensing boilers developed using condensing technology, which are preferably operated with gas and oil, produce a significant energy gain compared to conventional boilers by partially utilising the condensation heat of the water vapour formed during combustion and by almost completely exploiting the sensible heat, i.e. the conventional exhaust gas losses. The use of exhaust gas heat using condensing technology leads to a reduction in exhaust gas temperatures to as much as 40° C, which is significantly lower than the exhaust gas temperatures of conventional boilers of 160 - 180° C. When the exhaust gases from condensing boilers fall below the dew point range, the problem of increased condensate formation occurs. Sulphurous acid is produced in the exhaust gas pipes of coal and oil-fired condensing heating and combustion systems under excess pressure, which causes increased corrosion stress on the exhaust gas pipes.

Bei Schornsteinen sowie Abgas- und Abdampfleitungen, die mit den auf dem Markt angebotenen Edelstahl-Rohrelementen der gattungsgemäßen Art erstellt werden, besteht die Gefahr, daß die Rohrelemente im Bereich der Rohrkupplungen unter Einwirkung der sich in dem Ringspalt zwischen dem Muffenende eines Rohrelementes und dem Einsteckende eines zweiten Rohrelementes sammelnden schwefligen Säure, die sich aus dem Wasser des kondensierenden Wasserdampfes und Schwefelanteilen aus dem Abgas bildet, nach verhältnismäßig kurzer Betriebsdauer durchkorrodieren. Dies gilt im besonderen für waagrecht verlegte Leitungen wegen der Kapillarwirkung des Ringspaltes zwischen Muffenende und Einsteckende der Rohrkupplungen. Ein weiterer Nachteil dieser bekannten Bausysteme ist in der zeit- und arbeitsaufwendigen Montage zu sehen, die darauf beruht, daß die Rohrkupplungen der Rohrelemente durch Klemmbänder gesichert werden müssen (Selkirk Schornsteintechnik GmbH, Planungsunterlagen - Das Edelstahl-Einsatzrohr mit Multifunktion, 4/94).In the case of chimneys and exhaust and steam pipes, which are constructed using the stainless steel pipe elements of the generic type available on the market, there is a risk that the pipe elements in the area of the pipe couplings will corrode after a relatively short period of operation due to the effect of the sulphurous acid that collects in the annular gap between the socket end of one pipe element and the plug end of a second pipe element, which is formed from the water in the condensing steam and sulphur components from the exhaust gas. This applies in particular to horizontally laid pipes due to the capillary effect of the annular gap between the socket end and plug end of the pipe couplings. Another disadvantage of these known construction systems is the time-consuming and labor-intensive assembly, which is based on the fact that the pipe couplings of the pipe elements have to be secured with clamps (Selkirk Schornsteintechnik GmbH, planning documents - The stainless steel insert pipe with multi-function, 4/94).

Der Erfindung liegt die Aufgabe zugrunde, ein Rohrelement aus Edelstahl der gattungsgemäßen Art mit einer funktionssicheren Rohrkupplung zum L Erstellen von Schornsteinen sowie Abgas- und Abdampfleitungen zu entwickeln.The invention is based on the object of developing a pipe element made of stainless steel of the generic type with a functionally reliable pipe coupling for the construction of chimneys as well as exhaust gas and exhaust steam pipes.

Diese Aufgabe ist erfindungsgemäß gelöst durch ein Rohrelement mit den Merkmalen des Schutzanspruches 1.This object is achieved according to the invention by a pipe element with the features of claim 1.

Die Unteransprüche sind auf zweckmäßige Ausgestaltungen des Rohrelementes gerichtet.The subclaims are directed to expedient embodiments of the tubular element.

Das erfindungsgemäße Rohrelement zeichnet sich durch folgende Vorteile aus:The pipe element according to the invention is characterized by the following advantages:

Die Rohrkupplung, bei der das Einsteckende eines ersten Rohrelementes in das Muffenende eines zweiten Rohrelementes in einen Dichtungsring bis an die Innenschulter einer denThe pipe coupling in which the male end of a first pipe element is inserted into the female end of a second pipe element into a sealing ring up to the inner shoulder of a

Dichtungsring aufnehmenden Innensicke eingeschoben wird, die in den inneren Abschnitt des Muffenendes des ersten Rohrelementes eingeformt ist, gewährleistet, daß die Innenräume der beiden Rohrelemente im Bereich einer Rohrkupplung vollkommen gegen den Ringspalt zwischen dem Muffenende des einen Rohrelementes und dem Einsteckende des anderen Rohrelementes abgedichtet ist, so daß der Eintritt von Kondensat und von schwefelhaltigen Abgasen aus dem Innenraum der Rohrelemente in den Ringspalt der Rohrkupplung ausgeschlossen ist und damit ein vorzeitiges Durchkorrodieren der Rohrelemente im Kupplungsbereich vermieden wird. Desweiteren ermöglicht die Kupplungskonstruktion eine absolut glattflächige Abgasführung. Die Noppen im Muffenende eines ersten Rohrelementes zur Führung des Einsteckendes eines zweiten Rohrelementes ermöglichen eine gute Belüftung des Ringspaltes der Rohrkupplung, so daß Schwitzwasser, das sich insbesondere bei doppelwandigen Schornsteinen sowie Abgas- und Abdampfleitungen bei intermittierender Feuerung auf dem Außenmantel des Innenrohres bildet und in den Ringspalt der Rohrkupplungen läuft, bei Erwärmung des Innenrohres verdampfen kann. Schließlich wird der Zusammenbau der Rohrelemente gegenüber den bekannten Rohrelementen wesentlich erleichtert zum einen dadurch, daß die bajonettverschlußartige Verriegelung der Rohrkupplungen die Verwendung von Klemmbändern überflüssig macht und zum anderen durch die Anordnung des Dichtungsringes der Rohrkupplungen in einer Innensicke, die in den inneren Abschnitt des Muffenendes eingeformt ist, derart, daß beim Zusammenstecken zweier Rohrelemente erst zum Schluß Kraft zum Einkuppeln und Verriegeln der Rohrelemente aufgebracht werden muß.The sealing ring is inserted into the inner bead that is molded into the inner section of the socket end of the first pipe element, ensuring that the interior of the two pipe elements in the area of a pipe coupling is completely sealed against the annular gap between the socket end of one pipe element and the insertion end of the other pipe element, so that the entry of condensate and sulfur-containing exhaust gases from the interior of the pipe elements into the annular gap of the pipe coupling is excluded, thus preventing premature corrosion of the pipe elements in the coupling area. Furthermore, the coupling design enables an absolutely smooth exhaust gas routing. The nubs in the socket end of a first pipe element for guiding the insertion end of a second pipe element enable good ventilation of the annular gap of the pipe coupling, so that condensation, which forms on the outer casing of the inner pipe in double-walled chimneys and exhaust gas and steam pipes during intermittent firing and runs into the annular gap of the pipe couplings, can evaporate when the inner pipe is heated. Finally, the assembly of the pipe elements is made much easier compared to the known pipe elements, firstly because the bayonet-type locking of the pipe couplings makes the use of clamping bands superfluous and secondly because the sealing ring of the pipe couplings is arranged in an inner bead that is formed in the inner section of the socket end, such that when two pipe elements are put together, force only has to be applied at the end to couple and lock the pipe elements.

Die Erfindung ist nachstehend anhand von Zeichnungen erläutert. Es zeigtThe invention is explained below with reference to drawings. It shows

In den inneren Abschnitten 5 des Muffenendes 2 des Rohrelementes 1 ist eine Innensicke 6 mit einem Trapezprofil eingeformt, in die ein Dichtungsring 7 aus hitzebeständigem Material mit umlaufenden Dichtungszungen 8 auf der Ringinnenseite eingelegt ist.In the inner sections 5 of the socket end 2 of the pipe element 1, an inner bead 6 with a trapezoidal profile is formed, into which a sealing ring 7 made of heat-resistant material with circumferential sealing tongues 8 is inserted on the inside of the ring.

In den äußeren Abschnitt 9 des Muffenendes 2 des Rohrelementes 1 sind paarweise mit Abstand in axialer Richtung und in ümfangsrichtung angeordnete, radial nach innen gerichtete Distanz- und Führungsnoppen 10 für das bis an die Innenschulter 11 der Innensicke 6 einzuschiebende, durch den Dichtungsring 7 gegen das Muffenende 2 des Rohrelementes 1 abgedichtete Einsteckende 3 eines weiteren Rohrelementes 1 eingeformt.Radially inwardly directed spacer and guide knobs 10 are formed in the outer section 9 of the socket end 2 of the pipe element 1, arranged in pairs at a distance in the axial direction and in the circumferential direction, for the insertion end 3 of another pipe element 1, which is to be inserted up to the inner shoulder 11 of the inner bead 6 and sealed against the socket end 2 of the pipe element 1 by the sealing ring 7.

Auf der Außenseite 12 des Einsteckendes 3 des Rohrelementes 1 sind in Ümfangsrichtung verlaufende Flachringsegmente 13 mit Abstand angeschweißt. Durch eine Relativdrehung zweier zusammengesteckter Rohrelemente 1 verrasten die am Einsteckende 3 des einen Rohrelementes 1 angeordneten Flachringsegmente 13 bajonettverschlußartig mit den beiden Noppen 10 von jeweils zwei Noppenpaaren 10, 10 im Muffenende 2 des anderen Rohrelementes 1.Flat ring segments 13 running in the circumferential direction are welded at a distance from one another on the outside 12 of the insertion end 3 of the pipe element 1. By rotating two pipe elements 1 together relative to one another, the flat ring segments 13 arranged on the insertion end 3 of one pipe element 1 lock in place like a bayonet with the two studs 10 of two pairs of studs 10, 10 in the socket end 2 of the other pipe element 1.

Die Rohrkupplung 4 der Rohrelemente 1 gewährleistet, daß die Innenräume der Rohrelemente 1 im Bereich der Rohrkupplung vollkommen gegen den Ringspalt 14 zwischen dem Muffenende 2 des einen Rohrelementes 1 und dem Einsteckende 3 des anderen Rohrelementes 1 abgedichtet sind.The pipe coupling 4 of the pipe elements 1 ensures that the interior spaces of the pipe elements 1 in the area of the pipe coupling are completely sealed against the annular gap 14 between the socket end 2 of one pipe element 1 and the plug-in end 3 of the other pipe element 1.
