Abstract

Procédé de fabrication uniquement par cintrage d'un tube double en forme de coude avec un espace creux intermédiaire. Le procédé consiste en ce que : a. sur le tube à haute pression déjà coudé on glisse d'un seul côté le tube-enveloppe encore rectiligne; b. on introduit les deux tubes dans un dispositif de cintrage de manière que le tube à haute pression coudé soit dégagé latéralement et que le tube-enveloppe soit saisi par les organes du dispositif à cintrer qui effectuent le cintrage du tube-enveloppe; et c. on déforme le tube-enveloppe sur le tube à haute pression dégagé, en maintenant l'espace creux intermédiaire, jusqu'à ce que l'extrémité du coude du tube à haute pression soit atteinte. Applications à la fabrication de tubes doubles coudés soumis à de hautes pressions de service, pour échangeurs de chaleur, réacteurs tubulaires et analogues.
