Description

  

   <Desc/Clms Page number 1> 
 



  Schraubenförmig   gelilltes   Wellrohr. 



   Die bekannten   schraubenförmig gerillten   Wellrohre aus organischen oder anorganischen Stoffen mit Armierung durch zwischen den Schraubenwindungen des Rohres befindlichen, an diesen anliegenden inneren und äusseren Drahtwindungen leiden bei axialer Druck-bzw. Zugbeanspruchung an dem Mangel, dass sie sich zufolge Vertiefung bzw. Verflachung ihrer   Oberflächenwellung   verkürzen bzw. verlängern u. zw. dies umsomehr, je dünnwandiger und demzufolge biegsamer sie sind. 



   Vorliegende Erfindung begegnet diesem Mangel dadurch, dass die einander benachbarten, inneren und   äusserenDrahtwindungen nur durch   die Rohrwand von einander getrennt sind, wie dies die Figur zeigt. 



   Derartig ausgestattete Wellrohre können mit Vorteil als Schläuche für unter Druck stehende, Gase und Flüssigkeiten verwendet werden.

  Corrugated pipe with a screw shape.



   The known helically grooved corrugated pipes made of organic or inorganic materials with reinforcement by inner and outer wire windings located between the screw windings of the pipe and resting against them suffer from axial pressure or pressure. Tensile stress on the defect that they shorten or lengthen u due to deepening or flattening of their surface corrugation. between the thinner-walled and consequently more flexible they are, the more so.



   The present invention overcomes this deficiency in that the inner and outer wire turns adjacent to one another are only separated from one another by the pipe wall, as the figure shows.



   Corrugated pipes equipped in this way can be used with advantage as hoses for pressurized gases and liquids.
