Abstract

Elément de tuyau multiparois, du type constitué par une pluralité de tubes métalliques concentriques présentant des espaces intercalaires garnis d'un matériau de remplissage. Conformément à l'invention, l'espace intercalaire entre les tuyaux concentriques 1, 2 aux extrémités de l'élément de tuyau est obturé au moyen d'une bague métallique 4. L'invention s'applique aux canalisations immergées destinées au transport à grande distance de produits liquides ou gazeux.
