Claims (6)

1. Rohrflanschdichtung für thermisch höherbelastete Gasleitungen oder Trinkwaserleitungen mit angeschlossenen Feuerlöschsystemen, mit einem in Bezug auf das durch den Rohrflansch strömende Medium innenliegenden, relativ weichen Dichtbereich (10) aus Gummi und einem den Dichtbereich (10) umgebenden, die Axialkräfte in dem Rohrflansch aufnehmenden, starren Stützbereich (11), dadurch gekennzeichnet, daß sich der starre Stützbereich (11) aus einem flachen Metallring (14) sowie Graphitauflagen (17) auf beiden Seiten des Metallrings (14) zusammensetzt, und daß der weiche Dichtbereich (10) entlang seines Innenrandes einen Dichtwulst (12) von im wesentlichen kreisförmigem Querschnitt aufweist, dessen Durchmesser (D2) größer ist als die Dicke (D1) des Metallrings (14) einschließlich der Graphitauflagen (17).1. Pipe flange seal for thermally more highly stressed gas pipes or drinking water pipes with connected fire extinguishing systems, with a relatively soft sealing area ( 10 ) made of rubber with respect to the medium flowing through the pipe flange and a sealing area ( 10 ) surrounding the sealing area ( 10 ) that absorbs the axial forces in the pipe flange. rigid support area ( 11 ), characterized in that the rigid support area ( 11 ) is composed of a flat metal ring ( 14 ) and graphite pads ( 17 ) on both sides of the metal ring ( 14 ), and that the soft sealing area ( 10 ) along its inner edge has a sealing bead ( 12 ) of essentially circular cross section, the diameter (D 2 ) of which is greater than the thickness (D 1 ) of the metal ring ( 14 ) including the graphite layers ( 17 ). 2. Rohrflanschdichtung nach Anspruch 1, gekennzeichnet durch eine zahnartige Profilierung (18) der Verbindungsflächen der Graphitauflagen (17) mit dem Metallring (14).2. Pipe flange seal according to claim 1, characterized by a tooth-like profile ( 18 ) of the connecting surfaces of the graphite pads ( 17 ) with the metal ring ( 14 ). 3. Rohrflanschdichtung nach Anspruch 1 oder Anspruch 2, dadurch gekennzeichnet, daß ein äußerer Dichtabschnitt (13) des Dichtbereiches (10) aus zwei zueinander parallelen Gummilippen (15) sowie einem zwischen die Gummilippen (15) ragenden Flanschabschnitt (14a) des Metallrings (14) besteht, wobei die Dicke des Flanschabschnittes (14a) geringer ist als die Dicke des Metallrings (14) einschließlich der Graphitauflagen (17).3. Pipe flange seal according to claim 1 or claim 2, characterized in that an outer sealing portion ( 13 ) of the sealing region ( 10 ) from two mutually parallel rubber lips ( 15 ) and between the rubber lips ( 15 ) projecting flange portion ( 14 a) of the metal ring ( 14 ), the thickness of the flange section ( 14 a) being less than the thickness of the metal ring ( 14 ) including the graphite layers ( 17 ). 4. Rohrflanschdichtung nach Anspruch 3, dadurch gekennzeichnet, daß der Flanschabschnitt (14a) einstückiger Bestandteil des Metallrings (14) ist.4. Pipe flange seal according to claim 3, characterized in that the flange portion ( 14 a) is an integral part of the metal ring ( 14 ). 5. Rohrflanschdichtung nach einem der Ansprüche 1 bis 4, dadurch gekennzeichnet, daß der Metallring (14) aus Stahl besteht.5. Pipe flange seal according to one of claims 1 to 4, characterized in that the metal ring ( 14 ) consists of steel. 6. Rohrflanschdichtung nach einem der Ansprüche 3 bis 5, dadurch gekennzeichnet, daß die Dicke des äußeren Dichtabschnittes (13) des Dichtbereiches (10) gleich der Dicke des Metallrings (14) einschließlich der Graphitauflagen (17) ist.6. Pipe flange seal according to one of claims 3 to 5, characterized in that the thickness of the outer sealing portion ( 13 ) of the sealing region ( 10 ) is equal to the thickness of the metal ring ( 14 ) including the graphite pads ( 17 ).
