Description

  

  Rohr aus von einem     Bindemittel    durchsetztem Fasermaterial und Verfahren zur  Herstellung desselben.    Die vorliegende Erfindung bezieht sich  auf ein Rohr aus von einem Bindemittel  durchsetztem Fasermaterial, sowie auf ein  Verfahren zur Herstellung desselben.  



  Bis dahin war es üblich, solche Röhren  mit Hilfe von Metallflanschen zu verbinden.  Gemäss der Erfindung besitzt das Rohr  aus von einem Bindemittel durchsetztem  Fasermaterial mindestens ein zur Verbin  dung des Rohres mit einem andern Rohr  bestimmtes Organ, welches aus dem gleichen  Material besteht wie der übrige Teil des  Rohres.  



  Bei dem Verfahren nach der Erfindung  wird dieses Verbindungsorgan     nachträglich     am Rohr angebracht.     Zweckmässigerweise     hat das Verbindungsorgan     Flanschenform     und wird zum Beispiel dadurch hergestellt,  dass eine Form um das     aufgerauhte    Ende  des Rohres gelegt wird, in welche das nasse  Material     eingepresst    wird, bei dessen Trock  nung durch die     Aufrauhung    des Rohres eine    gute Haftung zwischen Flansch und Rohr  bewirkt wird.  



  Der Flansch kann wie folgt am Rohr  angebracht werden:  Nachdem der eine Endumfang beispiels  weise eines     Asbestzementrohres    auf der  Aussenseite etwa durch Schneiden eines  groben Gewindes zackig gemacht oder auf  gerauht worden ist, wird eine passende Form  um das Rohrende gelegt und nasser Asbest  zement in dieselbe eingebracht, welcher  hierauf vermittelst einer Presse auf das  Rohr     aufgepresst    wird. Die     Aufrauhung    des  Rohres dient dazu, die Haftung zwischen  demselben und dem Flansch zu vermehren.  



  In die Form kann vor dem     Aufpressen     des Flansches eine     Armierung    eingelegt       werden.     



  Solche Flansche können     vollständig    eben  oder auf der Stirnfläche mit Nuten irgend  welcher Art versehen sein; sie können auch  geschlitzt oder mit Löchern ausgerüstet sein,  die bei der Herstellung in dieselben hinein-      geformt wurden und die sich zur Aufnahme  von     Mutterschrauben    eignen, mit welchen  die Flansche in der für Metallrohre übli  chen Weise zusammengezogen werden kön  nen. Sie können auch mit Dichtungsschei  ben versehen sein, die in zwischen den Flan  schen angeordneten Vertiefungen liegen, und  es können diese Rohre gleich wie gewöhn  liche     Metallflanschenrohre    ausgebildet und  behandelt werden.  



       Asbestzementrohre,    die in der beschrie  benen Weise hergestellt werden, sind viel  billiger als die gewöhnliche Sorte mit Me  tallflanschen und sind denselben in der       Praxis    ebenbürtig.



  Tube made of fiber material permeated by a binding agent and method for producing the same. The present invention relates to a pipe made of fiber material permeated by a binding agent, and to a method for producing the same.



  Until then, it was customary to connect such tubes with the help of metal flanges. According to the invention, the pipe made of fiber material penetrated by a binding agent has at least one organ intended for connecting the pipe to another pipe, which organ consists of the same material as the rest of the pipe.



  In the method according to the invention, this connecting element is subsequently attached to the pipe. The connecting element is expediently in the form of a flange and is produced, for example, by placing a shape around the roughened end of the pipe into which the wet material is pressed, and when it dries, the roughening of the pipe causes good adhesion between the flange and the pipe .



  The flange can be attached to the pipe as follows: After one end circumference, for example, of an asbestos cement pipe on the outside, for example by cutting a coarse thread, has been made jagged or roughened, a suitable shape is placed around the pipe end and wet asbestos cement is introduced into the same which is then pressed onto the pipe by means of a press. The roughening of the pipe serves to increase the adhesion between the same and the flange.



  Reinforcement can be inserted into the mold before the flange is pressed on.



  Such flanges can be completely flat or provided with grooves of any kind on the end face; they can also be slotted or equipped with holes which were formed into the same during manufacture and which are suitable for receiving nut bolts with which the flanges can be drawn together in the manner customary for metal pipes. You can also be provided with sealing washers, which are located in recesses arranged between the flanges, and these tubes can be designed and treated the same as usual Liche metal flange tubes.



       Asbestos cement pipes, which are manufactured in the manner described enclosed, are much cheaper than the usual variety with Me tallflanschen and are the same in practice.
