Abstract

Les trous de la plaque tubulaire présentent des lèvres annulaires 12, 13, 14 dirigées l'une vers l'autre réalisées dans deux tôles métalliques 1, 2 placées parallèlement et destinées à recevoir les extrémités des tubes 7, 8, 9, 10. Un appareil de mandrinage 16 dont l'élément actif est un tampon en caoutchouc dur dilatable 32 est introduit dans l'extrémité du tube lorsque celui-ci a été introduit dans le trou de la plaque tubulaire, et la dilatation radiale du tampon vers l'extérieur donne un joint étanche entre la paroi du tube 7 et les lèvres annulaires 12.
