Abstract

Ce tuyau flexible est du type constitué en un feuillard en alliage d'aluminium, dont au moins la face destinée à former la paroi intérieure du tuyau est revêtue d'une couche de matière insensible aux fumées, telle qu'un époxy-phénol. Chaque couche protectrice en matière insensible à l'humidité et aux fumées, est recouverte d'une seconde couche, beaucoup plus souple, et présentant de bonnes qualités d'accrochage à la première couche.This flexible pipe is of the type consisting of a strip of aluminum alloy, at least the face intended to form the inner wall of the pipe of which is coated with a layer of material insensitive to fumes, such as an epoxy-phenol. Each protective layer made of material insensitive to humidity and fumes, is covered with a second layer, much more flexible, and having good bonding qualities to the first layer.

"TUYAU FLEXIBLE POUR TUBAGE DE CHEMINEE"  "FLEXIBLE PIPE FOR CHIMNEY TUBING"

La présente invention concerne un perfectionnement aux tuyaux flexibles pour tubages de cheminées décrits et revendiqués dans le brevet principal et qui sont généralement réalisés en feuillard d'alliage d'aluminium  The present invention relates to an improvement to the flexible pipes for chimney casings described and claimed in the main patent and which are generally made of aluminum alloy strip

ou d'acier inoxydable.or stainless steel.

Le brevet principal vise à améliorer la longévité des tubages de cheminées pour diminuer la fréquence de leurs remplacements et, par conséquent, réduire le coût de l'entretien des cheminées équipées de tels tubages, même lorsqu'ils sont utilisés pour des fumées très corrosives comme celles émises par des appareils à condensation A cet effet, au moins la face destinée à former la paroi interne du tuyau, est revêtue d'une couche de matière insensible aux fumées, telle qu'un époxy-phénol Dans un tel tubage, le feuillard en alliage d'aluminium joue le rôle de support mécanique introduit dans la cheminée et la couche de matière insensible aux fumées a pour effet de protéger le feuillard contre la corrosion, en  The main patent aims to improve the longevity of chimney casings to reduce the frequency of their replacements and, consequently, reduce the cost of maintaining chimneys equipped with such casings, even when used for highly corrosive fumes such as those emitted by condensing appliances For this purpose, at least the face intended to form the inner wall of the pipe, is coated with a layer of material insensitive to fumes, such as an epoxy-phenol In such a casing, the strip made of aluminum alloy acts as a mechanical support introduced into the chimney and the layer of material insensitive to fumes has the effect of protecting the strip against corrosion, in

supprimant tout contact entre lui et les fumées.  removing all contact between him and the fumes.

Cependant, à l'usage, il s'est avéré que le caractère cassant de la matière de la couche de protection, notamment lorsqu'elle est constituée par de la résine époxy-phénol, provoquait, soit lors de la mise en place du tubage ou autre manutention, soit ultérieurement, par suite, notamment, de  However, in use, it has been found that the brittle nature of the material of the protective layer, especially when it is constituted by epoxy-phenol resin, caused, either during the introduction of the casing or other handling, or subsequently, as a result, in particular, of

chocs thermiques, des fissurations annihilant l'effet protecteur recherché.  thermal shocks, cracks annihilating the desired protective effect.

Pour y remédier, selon la présente invention, chaque couche protectrice en matière insensible à l'humidité et aux fumées, est recouverte d'une seconde couche, beaucoup plus plastique, et présentant de bonnes  To remedy this, according to the present invention, each protective layer of material insensitive to moisture and smoke, is covered with a second layer, much more plastic, and having good

qualités d'accrochage à la première couche.  bonding qualities in the first layer.

La présence de cette seconde couche a pour effet de concilier, grâce à sa souplesse, la résistance à la corrosion et la protection mécanique  The presence of this second layer has the effect of reconciling, thanks to its flexibility, corrosion resistance and mechanical protection

du feuillard, par un effet auto-cicatrisant.  of the strap, by a self-healing effect.

Dans le cas o la première couche est constituée par une résine époxyphénol, la seconde couche est avantageusement constituée par un  In the case where the first layer consists of an epoxyphenol resin, the second layer is advantageously constituted by a

vernis polyamide, tel qu'un polyuréthane.  polyamide varnish, such as polyurethane.

Avantageusement, cette double protection, par deux couches superposées, d'un revêtement insensible aux fumées, telle qu'une résine époxy-phénol et d'un revêtement plus souple, tel qu'un polyamide, comme le polyuréthane, est appliquée sur les deux faces, interne et externe, du tuyau  Advantageously, this double protection, by two superimposed layers, a smoke-insensitive coating, such as an epoxy-phenol resin and a softer coating, such as a polyamide, such as polyurethane, is applied to both faces, internal and external, of the pipe

flexible.flexible.
