Description

  

  Einrichtung an Leitungen für Wasser, Gas usw. zur Verminderung der Korrosion.    Gegenstand vorliegender Erfindung ist  eine     Einrichtung    an aus Metall bestehende       Leitungen    für Gas, Wasser usw.  



  Es ist bekannt, dass die Korrosion von sol  chen     Leitungen    durch die elektrischen Ströme  sehr gefördert wird.  



       Vorliegende    Erfindung bezweckt die Kor  rosion zu vermindern, und zwar     wird    dies er  findungsgemäss dadurch erreicht, dass zwi  schen zwei aufeinanderfolgenden Leitungs  teilen elektrisch isolierende Zwischenlagen  eingebaut sind. Je nach der Anlage     können     dabei eine oder mehrere solcher Einrichtun  gen vorgesehen werden. Die Einrichtung  kann z. B. in Form von Rohrverschraubun  gen, sogenannten     Raccords;    ausgebildet sein.  



  In der     beiliegenden        Zeichnung    ist ein  Ausführungsbeispiel des Erfindungsgegen  standes schematisch dargestellt.  



  Am Rohrteil 1 ist ein Nippel 3 ange  schraubt, der mit einem     Aussengewinde    4     ver-          sehenist.    Am Rohrteil 2 ist eine Muffe 5 an  geschraubt, die mit ihrem Flansch 6 das Ge-    winde 4 des Nippels 3 übergreift. Der     Flansch     6 besitzt auf der     Innenwandung        Gewinde    7.  Zwischen den     Gewinden    4 und 7     ist    ein aus  elektrisch isolierendem Material bestehender  Körper 8 vorgesehen, der z. B. aus Hart  g<U>ummi</U>,     Kunstharz    usw. bestehen kann.

    In einer Ringfläche 9 der Muffe 5 liegt  ein     Ring    10 aus     elektrisch    isolierendem  Material, z.. B. aus     Vulcanfiber,        Klingerit     usw. Nippel 3 und Muffe 5 sind hart auf  einandergeschraubt.     'De@Scheibe    10 dient als  Dichtungsscheibe.

   Der     Gummikexper    8 kann       eingeschraubt    werden; es kann aber auch     eine     G<U>ummim</U>asse oder dergleichen, wenn pla  stisch,     in    die Fuge zwischen Nippel- 3 und  Muffe 5     eingegossen    werden.     Zwischen    die  Stirnflächen der Teile 1 und 2 kann noch     ein     Ring 11 aus     elektrisch    nicht     leitendem    Ma  terial gelegt werden.  



  Die Rohrteile 1 und 2 sind elektrisch  voneinander isoliert. Die Wirkung der Erd  ströme auf die Rohrleitungen und damit die  Korrosion der     letzteren    wird dadurch wesent  lich vermindert.



  Installation on pipes for water, gas, etc. to reduce corrosion. The present invention relates to a device on pipes made of metal for gas, water, etc.



  It is known that the corrosion of such lines is greatly promoted by the electrical currents.



       The present invention aims to reduce the corrosion, and this is achieved according to the invention in that electrically insulating intermediate layers are installed between tween two successive line parts. Depending on the system, one or more such facilities can be provided. The facility can e.g. B. in the form of Rohrverschraubun gene, so-called Raccords; be trained.



  In the accompanying drawing, an embodiment of the subject invention is shown schematically.



  A nipple 3, which is provided with an external thread 4, is screwed onto the pipe part 1. A sleeve 5 is screwed onto the pipe part 2 and with its flange 6 engages over the thread 4 of the nipple 3. The flange 6 has threads 7 on the inner wall. Between the threads 4 and 7, a body 8 made of an electrically insulating material is provided, which z. B. made of hard g <U> ummi </U>, synthetic resin, etc. can consist.

    In an annular surface 9 of the sleeve 5 there is a ring 10 made of electrically insulating material, for example vulcanized fiber, klingerite, etc. Nipple 3 and sleeve 5 are screwed hard onto one another. The @ washer 10 serves as a sealing washer.

   The Gummikexper 8 can be screwed in; However, a G <U> ummim </U> ace or the like, if plastic, can also be poured into the joint between the nipple 3 and socket 5. A ring 11 made of electrically non-conductive material can be placed between the end faces of parts 1 and 2.



  The pipe parts 1 and 2 are electrically isolated from one another. The effect of the earth currents on the pipelines and thus the corrosion of the latter is significantly reduced.
