Description

3030th

Die Erfindung betrifft einen Mehrlagenbehälter, bestehend aus einem Kernrohr und mehreren tragenden Lagen, mit Entgasungsbohrungen, bei dem zwischen dem Kernrohr und der innersten tragenden Lage eine Blindlage und auf dem Kernrohr aufstehend, der Anzahl der Entgasungsbohrungen entsprechende, Kernstopfen angeordnet sind.The invention relates to a multi-layer container, consisting of a core tube and several supporting ones Layers, with vent holes, in which there is one between the core tube and the innermost supporting layer Blind position and standing on the core tube, core plug corresponding to the number of degassing holes are arranged.

Entgasungsöffnungen von Mehrlagenbehältern haben den Zweck, Undichtigkeiten des Kernrohres anzuzeigen und im Sonderfall des Betriebes mit diffundierenden Gasen das durch das Kernrohr diffundierte Betriebsmittel schadlos abzuführen.The purpose of venting openings in multi-layer containers is to prevent leaks in the core tube and in the special case of operation with diffusing gases through the core tube to discharge diffused equipment without damage.

Im Falle besonders korrosiver Betriebsmedien besteht die Gefahr, daß bei einer Leckage im Kernrohr das Betriebsmittel die tragenden Lagen angreift. Es wird deshalb notwendig, die Spalte zwischen den tragenden Lagen im Bereich der Entgasungsöffnungen zu schützen. In the case of particularly corrosive operating media, there is a risk that if there is a leak in the core tube the equipment attacks the load-bearing layers. It is therefore necessary to clear the gap between the load-bearing Protect layers in the area of the vent openings.

Eine mögliche Lösung hierfür besteht in der Anwendung von Pfropfen-Schweißungen. Diese Ausführung besitzt jedoch verschiedene schweiß- und prüftechnische sowie auch betriebstechnische Nachteile.One possible solution to this is to use plug welds. This execution however, it has various welding and testing technology as well as operational disadvantages.

Der Erfindung liegt die Aufgabe zugrunde, einen Mehrlagenbehälter der eingangs genannten Gattung so auszugestalten, daß im Falle einer Undichtigkeit des Kernrohres Beschädigungen der tragenden Lagen mit Sicherheit vermieden werden. Gleichwohl sollen diese Entgasungsbohrungen wirtschaftlich herzustellen und Schweißnähte sicher auf ihre Brauchbarkeit zu überprüfen sein.The invention is based on the object of providing a multi-layer container of the type mentioned at the beginning to design that in the event of a leak in the core tube, damage to the load-bearing layers Security to be avoided. At the same time, these degassing wells should be produced economically and Weld seams must be safely checked for their usability.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Blindlage längsgeteilt ist und je zwei so entstandene benachbarte Teile einen Spaltkanal bilden, daß zentrisch zum Spaltkanal ein Kernstopfen derart in eine öffnung in der Blindlage und in mindestens einer tragenden Lage angeordnet ist, daß er in seinem oberen Bereich lediglich mit der bzw. den tragenden Lagen verschweißt ist und eine Bohrung aufweist, die direkt oder indirekt mit der Atmosphäre verbunden ist.According to the invention, this object is achieved in that the blind layer is divided lengthways and two in each case resulting adjacent parts form a gap channel that centrally to the gap channel a core plug in such a way an opening is arranged in the blind position and in at least one supporting position that it is in its upper one Area is only welded to the load-bearing layer or layers and has a hole that directly or is indirectly connected to the atmosphere.

Um aas Betriebsmedium, das infolge Undichtigkeit df;s Kernrohres durch dieses hindurchgetreten ist, sicher abführen zu können, weist nach einer vorteilhaften Ausgestaltung der Erfindung jeder Kernstopfen eine Gewindebohrung auf, in die ein Rohrstück geschraubt ist Auf seiner unteren, auf dem Kernrohr aufliegenden Fläche hat der Kernstopfen Nuten, die zweckmäßig kreuzweise angeordnet sind.To secure the operating medium that has passed through the core tube as a result of a leak to be able to discharge, according to an advantageous embodiment of the invention, each core plug has a Threaded hole into which a pipe section is screwed On its lower one, resting on the core pipe The core plug has grooves on its surface, which are expediently arranged crosswise.

Im Falle, daß der Korrosionsangriff des Betriebsmittels im Bereich der Schweißnähte des Kernrohres erfolgt ist es zweckmäßig, die Spaltkanäle direkt über den Längsnähten bzw. in deren unmittelbarer Nähe anzuordnen.In the event that the equipment is corrosive in the area of the weld seams of the core pipe it is advisable to place the split ducts directly above the longitudinal seams or in their immediate vicinity to arrange.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben. Es zeigtAn embodiment of the invention is shown in the drawing and will be described in more detail below described. It shows

Fig. 1 den Längsschnitt durch einen Mehrlagenbehälter im Ausschnitt mit einem EntgasungsrohrFig. 1 shows the longitudinal section through a multilayer container in the cutout with a degassing tube

F i g. 2 einen Querschnitt durch den Mehrlagenbehälter gemäß Pfeilrichtung IMI in F i g. 1.F i g. 2 shows a cross section through the multilayer container according to the direction of the arrow IMI in FIG. 1.

Der Mehrlagenbehälter 1 gemäß F i g. 1 und 2 besteht aus einem Kernrohr 2, einer Blindlage 3 und mehreren tragenden La£,en 4 als Hüllagen. Die Blindlage 3 ist mehrfach längsgeteilt und zwischen den so entstandenen Teilen verbleibt ein Spaltkanal 5. Dieser Spaltkanal ist im beschriebenen Ausführungsbeispiel über mindestens jeder Längsnaht des Kernrohres angeordnet und sollte ausreichend breit sein, damit das im Falle einer Undichtigkeit durch die Schweißnähte des Kernrohres 2 austretende Betriebsmedium sicher abgeführt werden kann. Mittig zum Spaltkanal 5 sind Entgasungsrohre 6 in der nachstehend beschriebenen Weise angeordnet: In der Blindlage 3 und in diesem Ausführungsbeispiel in den beiden sich daran anschließenden tragenden Lagen 4 ist eine alle drei Lagen durchdringende öffnung 7 angeordnet, in die ein Kernstopfen 8 aus korrosionsfestem Stahl eingesetzt ist. Der Kernstopfen 8 hat auf seiner unteren Fläche 9, mit der er auf dem Kernrohr 2 aufliegt, eine kreisförmige Bohrung 10 und von dieser nach außen führende radial angeordnete Nuten 11. In seinem oberen Bereich ist der Kernstopfen 8 mit den tragenden Lagen 4 austenitisch verschweißt. Diese Schweißnähte können vor Aufbringen d*5r weiteren tragenden Lagen 4 blecheben geschliffen und sorgfältig geprüft werden. In Verlängerung der kreisförmigen Vertiefung 10 durchdringt den Kernstopfen 8 eine Gewindebohrung 13, in die das untere Ende des Entgasungsrohres 6 dichtend eingeschraubt ist.The multi-layer container 1 according to FIG. 1 and 2 consists of a core tube 2, a blind layer 3 and several load-bearing La £, en 4 as cover layers. The blind position is 3 Split lengthways several times and a gap channel 5 remains between the resulting parts. This gap channel is arranged in the described embodiment over at least each longitudinal seam of the core tube and should be sufficiently wide so that in the event of a leak through the weld seams of the core tube 2 escaping operating medium can be safely discharged. In the center of the gap channel 5 are degassing tubes 6 in arranged in the manner described below: In the blind layer 3 and in this embodiment in The two adjoining load-bearing layers 4 have an opening 7 penetrating all three layers arranged, in which a core plug 8 made of corrosion-resistant steel is inserted. The core plug 8 has its lower surface 9, with which it rests on the core tube 2, a circular bore 10 and from this outwardly leading radially arranged grooves 11. In its upper area, the core plug 8 is with the supporting layers 4 austenitically welded. These weld seams can be further d * 5r before application load-bearing layers 4 sheet metal be ground and carefully checked. In extension of the circular Recess 10 penetrates the core plug 8, a threaded hole 13 into which the lower end of the Degassing tube 6 is screwed in a sealing manner.

Der besondere Vorteil der Erfindung liegt darin, daß es möglich ist, im Falle eines Leckes festzustellen, ob außer dem Kernrohr 2 auch die beiden ersten tragenden Lagen 4, mit denen der Kernstopfen 8 verschweißt ist, bereits durchkorrodiert sind. Das ist dann der Fall, wenn in die Entgasungsrohre 6 eingegebenes Druckgas in dem Spalt zwischen den Entgasungsrohren und der Mehrlagenwand austritt. Ein weiterer Vorteil der Erfindung besteht in der Entgasung der gesamten Mehrlagenwand und die Vermeidung der bei den bisherigen Pfopfen-Schweißungen zu beobachtenden örtlichen Schrumpfspannungen.The particular advantage of the invention is that it is possible in the event of a leak to determine whether In addition to the core tube 2, the first two load-bearing layers 4, to which the core plug 8 is welded, are already corroded. This is the case when pressurized gas entered into the degassing tubes 6 is in the gap between the degassing tubes and the multilayer wall emerges. Another benefit of the Invention consists in the degassing of the entire multilayer wall and the avoidance of the local shrinkage stresses observed in previous plug welds.
