Abstract

Dispositif de bridage intérieur des extrémités à souder de deux tuyaux ou autres éléments creux disposés bout à bout Il comporte deux supports annulaires 2 et 4 dans lesquels peut tourner un élément tubulaire 8 qui présente une ouverture alignée sur l'intervalle séparant les deux supports. Cet intervalle est lui-même aligné sur le joint 41 à souder entre les extrémités des tuyaux 9 et 11. Les supports portent des pistons 18 et 18' qui commandent des coins 26 et 26' d'expansion pouvant porter contre la surface intérieure des tuyaux et donner à ces derniers une section droite parfaitement circulaire. Domaine d'application : soudage bout à bout de tuyaux.
