Zwei Ausführungsbeispiele des erfindungsgemäßen Rohres sind in der Zeichnung dargestellt und werden nachfolgend beschrieben. Es zeigen:Two embodiments of the tube according to the invention are in the drawing are shown and are described below. Show it:
Fig. 1 halbseitig längsgeschnitten einen Abschnitt einer ersten Ausbildung des Rohres, und Fig. 1 cut longitudinally on one side a portion of a first embodiment of the tube, and
Fig. 2 in einer der Fig. 1 ähnlichen halbseitigen Längsschnittdarstellung einen Abschnitt einer zweiten Ausführungsform des Rohres. Fig. 2 in a half-section longitudinal section similar to Fig. 1 shows a portion of a second embodiment of the tube.
Fig. 1 zeigt eine Ausbildung des Rohres 10, das mindestens zwei Rohrteile 12 aus einem abrieb- und korrosionsfesten Material aufweist, die mit ihren einander zugewandten Stirnflächen 14 aneinander angrenzen und miteinander axial fluchtend mittels eines Klebers 16 verklebt sind. Das kann vor Ort geschehen. Fig. 1 shows comprising of a wear and corrosion resistant material, a formation of the tube 10, the at least two pipe parts 12 which are adjacent with their mutually facing end faces 14 against each other and are mutually axially aligned glued by an adhesive sixteenth That can happen on site.
Die miteinander fest verbundenen Rohrteile 12 sind mit einem Laminatgewebe 18 umwickelt, das mit einem Laminierharz 20 getränkt ist. Unmittelbar nach dem Umwickeln mit dem Laminiergewebe 18 und dem Tränken mit dem Laminierharz 20 wird am offenen Endabschnitt 22 des Rohres 10 ein Flansch 24 angeordnet, der mittels eines geeigneten Harzes am Rohr 10 fixiert wird, sobald das Laminierharz 20 ausgehärtet ist. The mutually firmly connected pipe parts 12 are wrapped with a laminate fabric 18 which is impregnated with a laminating resin 20 . Immediately after wrapping with the laminating fabric 18 and soaking with the laminating resin 20 , a flange 24 is arranged at the open end section 22 of the tube 10, which flange is fixed to the tube 10 by means of a suitable resin as soon as the laminating resin 20 has hardened.
Der Flansch 24 ist an seiner Stirnfläche radial innenseitig mit einer umlaufenden Rille 26 ausgebildet, in der ein Dichtungselement 28 angeordnet wird. Bei diesem Dichtungselement 28 handelt es sich bspw. um eine O-Ringdichtung.The flange 24 is formed on its end face radially on the inside with a circumferential groove 26 , in which a sealing element 28 is arranged. This sealing element 28 is, for example, an O-ring seal.
Fig. 2 zeigt eine Ausbildung des Rohres 10, bei welchem die Rohrteile 12 nicht miteinander axial fluchten, sondern - an die jeweiligen örtlichen Gegebenheiten angepaßt - miteinander einen stumpfen Winkel einschließen. Ein weiterer Unterschied zu dem in Fig. 1 verdeutlichten Rohr 10 besteht bei dem Rohr 10 gemäß Fig. 2 darin, daß der Flansch 24 kein Dichtungselement 28 aufweist. Im übrigen ist das Rohr 10 gemäß Fig. 2 prinzipiell ähnlich ausgebildet wie das in Fig. 1 gezeichnete Rohr 10, wobei gleiche Einzelheiten in Fig. 2 mit den selben Bezugsziffern wie in Fig. 1 bezeichnet sind, ohne daß alle diese Einzelheiten in Verbindung mit Fig. 2 noch einmal detailliert beschrieben werden. Fig. 2 shows an embodiment of the tube 10 , in which the tube parts 12 are not axially aligned with each other, but - adapted to the respective local conditions - enclose an obtuse angle with each other. Another difference from the tube 10 illustrated in FIG. 1 in the tube 10 according to FIG. 2 is that the flange 24 has no sealing element 28 . Moreover, the pipe 10 2 is shown in FIG. Basically formed similarly to the position shown in FIG. 1, tube 10, wherein the same details in FIG. 2 are denoted by the same reference numerals as in Fig. 1, without all those details in connection with Fig. 2 will be described again in detail.
