Abstract
Procédé pour fabriquer une conduite isolée (1) à double paroi du type comprenant un tube interne (2) et un tube externe (3) délimitant un espace (4) rempli de matériau isolant selon lequel, avant remplissage de l'espace compris entre le tube interne et le tube externe, on obstrue l'une des extrémités (5) dudit espace. On remplit ledit espace d'isolant constitué d'un granulat microporeux et on referme la deuxième extrémité (7) dudit espace par un joint (8) serti en laissant libre le mouvement longitudinal de l'extrémité du tube externe (3) par rapport à l'extrémité du tube interne (2).
