Title
(DE) UMMANTELTES ROHR UND ROHRVERBUND
(EN) COATED PIPE AND PIPE COMBINATION
(FR) TUYAU GAINÉ ET ASSEMBLAGE DE TUYAUX
Abstract
(DE)
Die Erfindung betrifft ein Rohr (100) mit einer Thermoplastmantelfläche (150) und einer die Thermoplastmantelfläche (150) umschließenden, glasfaserverstärkten Duroplastummantelung (180). Die Duroplastummantelung (180) ist von mehreren Lagen Glasfasermatte oder Glasfasergewebe oder einer Kombination aus beiden gebildet, wobei die Lagen im Naß-in-Naß-Verfahren unter Verwendung eines Vinylester-, Polyester- oder Epoxydharzes auf die Thermoplastmantelfläche (150) aufgebracht sind. Erfindungsgemäß ist dabei eine Außenlage (186) der Duroplastummantelung (180) von kreuzgewickeltem Glasfaservlies oder Glasfasergewebe gebildet.
(EN)
The invention relates to a pipe (100) having a thermoplastic casing surface (150) and a glass-fibre-reinforced thermo-setting coating (180) surrounding the thermoplastic casing surface (150). The thermo-setting coating (180) is formed from multiple layers of glass-fibre matting or glass-fibre fabric, or a combination of the two, wherein the layers are applied to the thermoplastic casing surface (150) in a wet-on-wet method using a vinylester, polyester or epoxy resin. According to the invention, an outer layer (186) of the thermo-setting coating (180) is formed from cross-wound glass-fibre fleece or glass-fibre fabric.
(FR)
L'invention concerne un tuyau (100) comprenant une surface extérieure thermoplastique (150) et une gaine thermodurcissable (180) renforcée par des fibres de verre, entourant la surface extérieure thermoplastique (150). La gaine thermodurcissable (180) est formée par plusieurs couches de nappe de fibres de verre ou d'un tissu de fibres de verre ou d'une combinaison de ces deux derniers. Les couches sont appliquées sur la surface extérieure thermoplastique (150) lors du procédé mouillé sur mouillé en utilisant une résine d'ester vinylique, de polyester ou époxy. Selon l'invention, une couche extérieure (186) de la gaine thermodurcissable (180) est formée par un non tissé de fibres de verre ou un tissu de fibres de verre enroulé en bobinage croisé.
