Abstract

Tuyau isolé thermiquement pour chauffage à distance, comportant un tuyau intérieur en acier prévu pour le passage du fluide calo-porteur, entouré avec espacement d'un tuyau extérieur en plastique maintenu en place au moyen d'entretoises, et dans lequel l'espace annulaire creux entre le tuyau intérieur et le tuyau extérieur est rempli d'un matériau isolant, une couche annulaire d'un matériau isolant minéral étant disposée sur le tuyau intérieur et l'espace annulaire restant étant rempli de mousse de polyuréthane. Comme matériau isolant minéral, on utilise une couche de fibres de verre ou de fibres minérales 5 et la couche isolante de fibres est comprimée.
