Abstract

Um ein defektes Wärmetauscherrohr (3) schnell und einfach zu re­ parieren, ist eine mechanisch verspannbare Reparatureinlage (1) vorgesehen. Die Reparatureinlage (1) besteht aus einer Hülse (5), durch die ein rohrförmiger Grundkörper (7) hindurchragt, der mit einem Kopfteil (9) an der Hülse (5) abgestützt ist und an dem anderen Ende mit einem Gewinde (11) und einer Mutter (13) zum Verspannen der Reparatureinlage (1) im Wärmetauscherrohr (2) versehen ist. Zwischen der Hülse (5) und dem Kopfteil (9) und zwischen der Hülse (5) und der Mutter (13) ist jeweils zu­ mindest ein Stülpring (15) angeordnet. Durch Festziehen der Mutter (13) verspannen sich die Stülpringe (15) und dichten die Reparatureinlage (1) gegen das Wärmetauscherrohr (3) ab. Mit dieser Reparatureinlage (1) ist eine schnelle Reparatur eines Wärmetauscherrohres (3) möglich, wodurch die Strahlenbelastung des Bedienpersonals niedrig gehalten wird. To quickly and easily replace a defective heat exchanger tube (3) parry is a mechanically tensioned repair insert (1) intended. The repair insert (1) consists of a sleeve (5), through which a tubular base body (7) projects, which is supported with a head part (9) on the sleeve (5) and at the other end with a thread (11) and a nut (13) for tightening the repair insert (1) in the heat exchanger tube (2) is provided. Between the sleeve (5) and the head part (9) and between the sleeve (5) and the nut (13) is closed at least one slip ring (15) arranged. By tightening the Mother (13) tighten the slip rings (15) and seal them Repair insert (1) against the heat exchanger tube (3). With this repair insert (1) is a quick repair of a Heat exchanger tube (3) possible, which reduces the radiation exposure the operator is kept low.
