Description

  

  Tuyau pour hautes pressions.    L'objet de l'invention est un tuyau pour  hautes pressions comportant une     double-          paroi,    l'espace annulaire     constitué    entre les  deux parois étant destiné à être rempli d'un  liquide à pression réduite, ce qui permet de  réduire l'épaisseur des parois du tuyau.  



  Le dessin annexé représente, à titre  d'exemple, une forme d'exécution de l'objet  de l'invention.  



  La     fig.    1 est une coupe longitudinale;  La     fig.    2 en est une coupe transversale  suivant la ligne     A-B    de la     fig.    1.  



  Le tuyau A comporte une paroi inté  rieure     e'    entre lesquelles est constitué un  espace annulaire<I>a.</I> Cet espace annulaire<I>a</I>  est relié à une tubulure t.  



  Cette disposition permet de diminuer l'é  paisseur des parois du tuyau car s'il doit par  exemple, supporter une haute pression d'eau  P et qu'on introduise dans l'espace a, par la  tubulure<I>t,</I> de l'eau à une pression<I>p</I> réduite,  la pression supportée par la paroi intérieure e  sera de     p--p.       Suivant l'invention il est possible, avec  deux tôles     distin.ctes    et d'épaisseur normale,  de réaliser un tuyau résistant à une pression  intérieure P qui aurait nécessité normalement  l'emploi d'une tôle unique d'épaisseur anor  male, étant donné l'outillage de fabrication  dont on dispose pratiquement.  



  Cette disposition est particulièrement  avantageuse pour l'établissement de condui  tes d'eau. pour de hautes chutes, mais il est  évident qu'elle peut être appliquée à la réali  sation de tuyaux devant supporter de fortes  pressions, autres que celles de chutes d'eau.



  Hose for high pressures. The object of the invention is a pipe for high pressures comprising a double wall, the annular space formed between the two walls being intended to be filled with a liquid at reduced pressure, which makes it possible to reduce the thickness of the pipes. pipe walls.



  The appended drawing represents, by way of example, an embodiment of the object of the invention.



  Fig. 1 is a longitudinal section; Fig. 2 is a cross section along the line A-B of FIG. 1.



  The pipe A comprises an interior wall e 'between which an annular space <I> a </I> is formed. This annular space <I> a </I> is connected to a pipe t.



  This arrangement makes it possible to reduce the thickness of the walls of the pipe because if it must for example withstand a high water pressure P and that one introduces into the space a, through the pipe <I> t, </ I> water at a reduced pressure <I> p </I>, the pressure supported by the inner wall e will be p - p. According to the invention it is possible, with two distinctive sheets of normal thickness, to produce a pipe resistant to an internal pressure P which would normally have required the use of a single sheet of abnormal thickness, given the manufacturing tools that are practically available.



  This arrangement is particularly advantageous for the establishment of water conduits. for high falls, but it is obvious that it can be applied to the realization of pipes having to withstand high pressures, other than those of water falls.
