  Gaine tubulaire adaptée au garnissage intérieur des conduites tubulaires. 



  La présente invention concerne une gaine tubulaire souple particulièrement adaptée au garnissage intérieur des conduites tubulaires par Le procédé de réversion. 



  Le procédé connu de réversion permet d'assurer La pénétration d'une gaine étanche dans La conduite en la retournant progressivement à partir d'un point de fixation situé à L'entrée de La conduite. 



  L'intérêt du procédé de réversion réside dans la pos-   sibilité, qu'il   donne, de faire progresser la gaine et par conséquent de garnir   intérieurement la   conduite sans la démonter et de réaliser ce garnissage sur n'importe quelle Longueur grâce à l'assemblage de tronçons de gaine, chaque tronçon pouvant atteindre une longueur de 500 m et même davantage. 



  L'exploitation du procédé de réversion comporte, suivant Les exploitants, différents types de gaines. 



  CeLLes-ci se différencient principalement par La conception et La construction de la carcasse mais ont 

 <Desc/Clms Page number 2> 

 généralement en commun La présence d'un revêtement constitué par une couche mince de matière plastique, dont La fonction prioritaire est d'assurer   L'étanchéité.   



  Un revêtement mince de ce genre, désigné habituellement sous Le terme de coating, peut également constituer un revêtement protecteur mais dans des limites évidemment plus restreintes qu'un revêtement plus épais. 



  L'objet de l'invention est de réaliser une gaine présentant une forte adhérence à La paroi de La conduite et une protection particulièrement efficace vis-àvis des sollicitations, teLLes que abrasion, corrosion et étanchéité. 



  Une gaine tubulaire souple suivant l'invention est caractérisée en ce qu'eLLe est obtenue par soudure longitudinale des bords Latéraux d'une nappe plane, composée d'une carcasse, comportant une couche de feutre solidarisée à un support textile résistant, et d'un revêtement protecteur, constitué par une couche d'élastomère thermodurcissable ou thermoplastique reliée à La carcasse par vulcanisation ou polymérisation. 



  La carcasse, composée d'un tissu à structure ouverte Lié à une couche de feutre, forme avec Le revêtement protecteur, constitué par une couche   d'élastomère,   un matériau composite. 



  L'invention est décrite maintenant avec plus de détails sur la base des dessins annexés, à titre d'exemples uniquement, montrant en :

 senté en figure 1, on voit La bobine d'enroulement de La gaine 1, La tête de retournement 2 et La pénétration de La gaine 3 dans La conduite rigide 4. En figure 3 on voit La gaine 3 fermée, telle qu'eLLe pénètre dans La conduite avant retournement. 



  Une gaine-souple suivant l'invention présente une forme tubulaire (figures 5A,5B) résultant du jonctionnement des deux bords Latéraux. La constitution de cette gaine comporte une carcasse textile 5 et un revêtement   6,   servant de couche de protection et d'étanchéité et fabriqué à partir d'élastomère thermoplastique ou thermodurcissable. 

 <Desc/Clms Page number 5> 

 



  La carcasse textile 5 se décompose en deux éléments : un tissu synthétique 7 et une couche de feutre 8. Le tissu 7 peut être constitué (figures   6A, 6B)   par une structure unidirectionnelLe formée par des fils longitudinaux 7', non assemblés ou assemblés par des fils transversaux 9 n'intervenant que pour assurer La stabilité de cette structure. 



  Le tissu de La carcasse 5   (figures 6C, 6D)   peut aussi être constitué par un tissu résultant du tissage de fils de chaîne et de trame et possédant une structure ouverte,   c'est-à-dire   présentant des vides   réguliers,   dont la dimension est égale ou supérieure à   L'épais-   
 EMI5.1 
 seur des fils. 



  Le tissu synthétique doit posséder une résistance déterminée pour s'opposer à l'allongement axial et à la dilatation radiale du revêtement soumis à la pression de retournement. 



  Le feutre 8 est aiguiLLeté sur une des faces du tissu unidirectionnel   (figures 7A, 78)   ou du tissu à structure ouverte (figures 8A, 8B), l'autre face restant non feutrée pour permettre Le calandrage et La   vulca-   nisation du revêtement. 



  Après la vulcanisation on constate   les résultats sui-   vants :   - L'adhérence   chimique entre Le caoutchouc et Le textile est renforcée par une adhérence mécanique résultant de la présence du caoutchouc entre Les fils, s'il s'agit d'un tissu unidirectionnel, ou dans les vides existants, s'il s'agit d'un tissu à structure ouverte ;
L'interpénétration entre Le feutre et Le caoutchouc 

 <Desc/Clms Page number 6> 

 à travers Le tissu solidarise les trois matières entre elles au point de former ensemble un matériau composite. 



  Dans la gaine suivant l'invention, la couche de feutre exerce deux fonctions, à savoir : avant Le retournement absorber une quantité suffisante de colle et assurer la stabilité de cette imprégnation jusqu'au moment de l'étalement de la gaine contre la paroi du tube rigide ; - influencer positivement la valeur du module d'élasticité de La structure composite dans Le sens transversal. 



  Le revêtement protecteur, constitué par une couche d'élastomère thermodurcissable ou thermoplastique d'épaisseur variable aménagée en fonction des soLLicitations, est fixé sur La carcasse par vulcanisation ou polymérisation. 
 EMI6.1 
 



  Le choix d'une composition ou d'une formulation spécifique répondant aux soLLicitations rencontrées s'étend à toutes Les ressources provenant de La diversité des élastomères thermodurcissables ou thermoplastiques. 



  Tel mélange sera utilisé pour résister à teLLe soLLicitation à L'abrasion, tandis qu'une formulation entièrement différente sera choisie pour résister à teLLe ou teLLe corrosion. 



  Grâce à La structure de La nappe suivant L'invention La soudure ou Le jonctionnement LongitudinaL est réaLisé dans L'épaisseur de La couche du revêtement, quelle que soit sa nature thermodurcissable ou thermoplastique (figures 5A, 5B). De ce fait, la soudure respecte Les propriétés élastiques du revêtement. 

 <Desc/Clms Page number 7> 

 Le jonctionnement, réalisé dans le revêtement élastomérique, peut être effectué à chaud ou à froid. 



  IL faut noter que La résistance de La soudure d'une nappe renforcée par un tissu unidirectionnel ou à structure ouverte est indépendante de La résistance du tissu Lui-même. 
 EMI7.1 
 



  La gaine faisant L'objet de La présente invention est formée par jonctionnement des bords Latéraux de La nappe sans en modifier autrement La composition. Par conséquent, La description de La composition caractéristique suivant L'invention peut s'appliquer indif- 
 EMI7.2 
 féremment à La nappe ou à La gaine. 



  Le jonctionnement LongitudinaL peut être réalisé dans L'épaisseur du revêtement sans incorporation du tissu dans La partie jonctionnée. Cette jonction est réaLisée par soudure vulcanisée. 



  Les deux extrémités sont préparées, par exemple, en forme de biseaux superposés L'un sur l'autre après enduction de coLLe. Les bords peuvent également être découpés,   de façon   à permettre un apport de matière sous forme, par exempLe, d'un ruban venant s'insérer dans l'emplacement créé entre Les deux bords. 



  Le revêtement protecteur constitué par La couche d'éLastomère se trouve, après Le retournement, en contact avec Les liquides véhiculés dans Le tube ou conduite rigide, tandis que l'autre face de La gaine constituée par La couche de feutre, qui a été, avant retournement, soigneusement imprégnée de résine, s'étaLe contre et en contact avec La paroi de ladite conduite. 



  Ultérieurement, en amenant la pression et la température 

 <Desc/Clms Page number 8> 

 aux conditions requises, la résine en se polymérisant assure une adhérence très élevée entre La conduite et La gaine caoutchoutée. 



  De   cette façon, o'n a bien réalisé   par une phase continue La fixation d'un revêtement protecteur fortement adhérent à la paroi et pouvant dès lors exercer, grâce à sa composition caoutchoutée, une protection particulièrement efficace vis-à-vis des sollicitations telles que abrasion, corrosion et étanchéité. 



  Dans une gaine suivant l'invention la carcasse recouverte par Le revêtement protecteur permet de s'opposer aux déformations provoquées par la réversion, grâce à la présence du textile, et d'absorber et de restituer au moment voulu La quantité de coLLe requise, grâce à la présence du feutre.

  Tubular sheath suitable for the interior lining of tubular conduits.



  The present invention relates to a flexible tubular sheath which is particularly suitable for lining the interior of tubular conduits by the reversion process.



  The known reversion process makes it possible to ensure the penetration of a sealed sheath into the pipe by gradually turning it over from a fixing point located at the entrance to the pipe.



  The advantage of the reversion process lies in the possibility that it gives of advancing the sheath and consequently of lining the pipe internally without dismantling it and of making this lining over any length thanks to the assembly of sheath sections, each section being able to reach a length of 500 m and even more.



  The exploitation of the reversion process includes, according to the operators, different types of sheaths.



  These differ mainly in the design and construction of the carcass but have

 <Desc / Clms Page number 2>

 generally in common The presence of a coating constituted by a thin layer of plastic material, the priority function of which is to ensure sealing.



  A thin coating of this kind, usually designated by the term coating, can also constitute a protective coating but within limits obviously more restricted than a thicker coating.



  The object of the invention is to produce a sheath having a strong adhesion to the wall of the pipe and a particularly effective protection against stresses, such as abrasion, corrosion and sealing.



  A flexible tubular sheath according to the invention is characterized in that it is obtained by longitudinal welding of the lateral edges of a flat sheet, composed of a carcass, comprising a layer of felt secured to a resistant textile support, and a protective coating, consisting of a layer of thermosetting or thermoplastic elastomer connected to the carcass by vulcanization or polymerization.



  The carcass, composed of an open structure fabric Linked to a layer of felt, forms with The protective coating, consisting of a layer of elastomer, a composite material.



  The invention is now described in more detail on the basis of the appended drawings, by way of examples only, showing in:

   Figures 9A and 9B a section in a sheath, of which La

 carcass, constituted respectively by a felted unidirectional fabric or by a felted open structure fabric, is covered by a protective coating, the tubular shape having been obtained by joining the lateral edges of the sheet in the thickness of the elastomeric coating; Figure 10 a section of a sheath according to the invention turned over and lining a rigid pipe; Figure 11 a section in a sheet characterized by a thickening of the coating in its central part; Figure 12 a section of the sheet having a thickened coating in the central part, and Figure 13 a section of the sheath with a thickened coating in its central part, as it is placed in a rigid pipe after turning.



  In the diagram of the known process of reversion, represented
 EMI4.1
 felt in FIG. 1, we see the winding coil of the sheath 1, the turning head 2 and the penetration of the sheath 3 into the rigid pipe 4. In FIG. 3 we see the sheath 3 closed, as it penetrates in Driving before turning.



  A flexible sheath according to the invention has a tubular shape (FIGS. 5A, 5B) resulting from the junction of the two lateral edges. The constitution of this sheath comprises a textile carcass 5 and a coating 6, serving as a protective and sealing layer and made from a thermoplastic or thermosetting elastomer.

 <Desc / Clms Page number 5>

 



  The textile carcass 5 is broken down into two elements: a synthetic fabric 7 and a layer of felt 8. The fabric 7 can be formed (FIGS. 6A, 6B) by a unidirectional structure formed by longitudinal wires 7 ′, not assembled or assembled by transverse son 9 intervening only to ensure the stability of this structure.



  The fabric of Carcass 5 (FIGS. 6C, 6D) may also consist of a fabric resulting from the weaving of warp and weft threads and having an open structure, that is to say having regular voids, the dimension of which is equal to or greater than Thick-
 EMI5.1
 sister of the sons.



  The synthetic fabric must have a determined resistance to oppose the axial elongation and the radial expansion of the coating subjected to the turning pressure.



  The felt 8 is sharpened on one of the sides of the unidirectional fabric (FIGS. 7A, 78) or of the fabric with an open structure (FIGS. 8A, 8B), the other face remaining non-felted to allow calendering and vulcanization of the coating.



  After vulcanization, the following results are noted: - The chemical adhesion between the rubber and the textile is reinforced by a mechanical adhesion resulting from the presence of the rubber between the threads, if it is a unidirectional fabric, or in existing voids, in the case of an open structure fabric;
The interpenetration between felt and rubber

 <Desc / Clms Page number 6>

 through The fabric joins the three materials together to the point of forming a composite material together.



  In the sheath according to the invention, the felt layer has two functions, namely: before turning over, absorbing a sufficient amount of glue and ensuring the stability of this impregnation until the sheath is spread against the wall of the rigid tube; - positively influence the value of the modulus of elasticity of the composite structure in the transverse direction.



  The protective coating, consisting of a layer of thermosetting or thermoplastic elastomer of variable thickness arranged according to the stresses, is fixed to the carcass by vulcanization or polymerization.
 EMI6.1
 



  The choice of a specific composition or formulation responding to the demands encountered extends to all resources coming from the diversity of thermosetting or thermoplastic elastomers.



  Such a mixture will be used to resist such abrasion stress, while an entirely different formulation will be chosen to resist such corrosion.



  Thanks to the structure of the sheet according to the invention The welding or the longitudinal joining is carried out in the thickness of the coating layer, whatever its thermosetting or thermoplastic nature (FIGS. 5A, 5B). Therefore, the weld respects the elastic properties of the coating.

 <Desc / Clms Page number 7>

 The joining, carried out in the elastomeric coating, can be carried out hot or cold.



  It should be noted that the resistance of the welding of a sheet reinforced by a unidirectional fabric or with an open structure is independent of the resistance of the fabric itself.
 EMI7.1
 



  The sheath forming the object of the present invention is formed by joining the lateral edges of the sheet without otherwise modifying the composition. Consequently, the description of the characteristic composition according to the invention can be applied indi-
 EMI7.2
 proudly at the tablecloth or at the sheath.



  Longitudinal joining can be carried out in the thickness of the covering without incorporating the fabric into the joined part. This junction is made by vulcanized welding.



  The two ends are prepared, for example, in the form of bevels superimposed on each other after coating with coLLe. The edges can also be cut, so as to allow a supply of material in the form, for example, of a ribbon coming to be inserted in the space created between the two edges.



  The protective coating constituted by the layer of elastomer is, after the inversion, in contact with the liquids conveyed in the tube or rigid pipe, while the other face of the sheath constituted by the layer of felt, which has been, before turning, carefully impregnated with resin, lies against and in contact with the wall of said pipe.



  Later, by bringing the pressure and the temperature

 <Desc / Clms Page number 8>

 under the requisite conditions, the polymerizing resin ensures very high adhesion between the pipe and the rubberized sheath.



  In this way, o'n has achieved a continuous phase The fixing of a protective coating strongly adherent to the wall and therefore able to exert, thanks to its rubberized composition, a particularly effective protection against stresses such that abrasion, corrosion and sealing.



  In a sheath according to the invention, the carcass covered by the protective coating makes it possible to oppose the deformations caused by the reversion, thanks to the presence of the textile, and to absorb and restore at the desired time The quantity of coLLe required, thanks the presence of felt.
