Abstract

The pipe joint has a sliding pipe compensator arranged at firmly and freely attached pipe ends, where a defined frictional connection and a labyrinth seal are provided in the pipe joint. The pipe ends are provided with pipe taper sections. A connection pipe is provided as a sword-shaped pipe between the pipe taper sections, where the connection pipe is provided with a taper angle of a pipe cross section. Packing material is provided on sealing surface of the pipe taper sections.

Description

Rohrleitungen sind infolge Temperaturänderungen der Leitungsinhalte oder der Umgebung Längenänderungen unterworfen, die durch eine elastische Gestaltung der Rohrleitungen ausgeglichen werden müssen. Ist die Leitung gerade und fest eingespannt, so muss die entstehende Rohrkraft (Zug oder Druck) von den Festpunkten aufgenommen werden. Der Extremwert der Längsspannungen im Rohr beträgt bei Stahlrohren rund 2,5 N/mm2 je K (Literatur). Anzustreben ist natürlicher Dehnungsausgleich durch Richtungswechsel der Rohre. Größere Längenänderungen können durch Dehnungsausgleicher aufgenommen werden. Bewährt haben sich Dehnungsbogen in U- oder Lyra-Form, die aus dem gleichen Werkstoff wie das Rohr bestehen. Sie sind betriebssicher und wartungsfrei, ab er sehr platzaufwendig. Um die entstehenden Kräfte, Biegemomente und Drehmomente auf ein erträgliches Maß zu reduzieren, werden die Rohre mit Vorspannung entgegen der Wärmedehnung montiert. Üblich ist eine Vorspannung von 50% der zu erwartenden Kraft.Pipelines are subject to changes in length due to temperature changes of the line contents or the environment, which must be compensated by an elastic design of the pipes. If the line is straight and firmly clamped, the resulting pipe force (tension or pressure) must be absorbed by the anchor points. The extreme value of the longitudinal stresses in the pipe in steel pipes is around 2.5 N / mm 2 per K (literature). The aim is to achieve natural expansion compensation by changing the direction of the pipes. Larger changes in length can be absorbed by expansion compensators. Elongation curves in U- or Lyra-form, which consist of the same material as the pipe, have proven to be useful. They are reliable and maintenance-free, from he very space consuming. In order to reduce the resulting forces, bending moments and torques to a tolerable level, the tubes are mounted with preload against the thermal expansion. A preload of 50% of the expected force is usual.

Beim Patentinhalt geht um die Beschreibung eines neuartigen Dehnungsausgleich durch besondere Bauelemente. Bekannt sind:

  • – LYRA- oder U-Bögen die aber alle an Festpunkteinspannungen gebunden sind.
  • – Balg-Kompensatoren sind wartungsfreie Dehnungsausgleicher mit geringstmöglichen Platzbedarf dazu gehören Linsenkompensatoren mit wenigen aber hohen Wellen für sehr große Durchmesser (DN 5000) sowie Ein- und Mehrfachbälge mit vielen niedrigen Wellen als ein- oder mehrlagigem kaltverformten Stahlblechen mit großem Dehnungsvermögen für hohe Drücke (DN 600: PN 100, DN 250: PN 250)
  • – bekannt sind weiterhin Gummi-Kompensatoren bis DN 400 (PN bei 100°C) sowie Gelenk-Kompensatoren
The patent content is about the description of a novel strain compensation by special components. Are known:
  • - LYRA or U-bows, which are all bound to fixed point instabilities.
  • - Bellows expansion joints are maintenance-free expansion joints with the smallest possible space requirements. These include lens compensators with few but high shafts for very large diameters (DN 5000) as well as single and multiple bellows with many low shafts as single or multi-layer cold-formed steel sheets with high elongation for high pressures (DN 600: PN 100, DN 250: PN 250)
  • - rubber expansion joints up to DN 400 (PN at 100 ° C) and joint compensators are also known

Beim Patentinhalt handelt es sich aber um einen neuartigen Gleitrohrkompensator der sowohl für frei als auch fest eingespannte Rohrenden verwendbar ist. Beide Rohrenden sind mit einem Rohrverjüngung ausgestattet zwischen den Rohrverjüngen wird ein Verbindungsrohr als Degenrohr eingesetzt, welches an seinen Enden jeweils auch mit dem Verjüngungswinkel des Rohrtquerschnitts ausgestattet ist. Für die Dichtflächen der beiden Rohrverjüngungen sind marktübliche Packungswerkstoffe zu verwenden. Man kann dieses Zwischenrohr sowohl als
