Title (EN) INTERNAL LINING FOR PIPE SURFACES AND METHOD OF LINING PIPES
(FR) REVÊTEMENT INTERNE DESTINÉ À DES SURFACES DE TUYAU ET PROCÉDÉ DE REVÊTEMENT DE TUYAUX
Abstract:
(EN) A pipe lining having at least two material layers, a first elastomeric layer spray applied directly to the inside of a pipe which acts as a hydrophobic, ductile membrane, and a second rigid layer is spray applied to the first layer prior to complete curing of the first layer. One or more additional layers may be applied to the second layer to provide additional abrasion, erosion or chemical resistance to the second layer. An intermediate reinforcing layer may be disposed between the first and second layers. The first layer cures into a closed cell elastomeric foam, such that stress and other forces are not passed from the pipe to the rigid second layer.
(FR) L’invention concerne un revêtement de tuyau ayant au moins deux couches de matériau, une première couche élastomère appliquée par pulvérisation directement à l'intérieur d'un tuyau qui agit comme une membrane ductile hydrophobe, et une seconde couche rigide étant appliquée par pulvérisation sur la première couche avant le durcissement complet de la première couche. Une ou plusieurs couches supplémentaires peuvent être appliquées à la seconde couche pour fournir une résistance à l’abrasion, à l’érosion ou chimique supplémentaire à la seconde couche. Une couche de renfort intermédiaire peut être disposée entre les première et seconde couches. La première couche durcit en une mousse élastomère à cellules fermées, de sorte que la contrainte et d'autres forces ne soient pas transmises du tuyau à la seconde couche rigide.
