Abstract

L'objet de l'invention concerne un procédé et un dispositif de protection interne de conduits sur le secteur de leur soudure circonférentielle. Il est constitué par l'adjonction à l'extrémité profilée jointive d'un tube, ou manchon dont la face interne est pourvue d'un revêtement protecteur et la périphérie externe d'un évidement au droit du cordon de soudure récepteur de telle garniture isotherme de protection étant précisé que cet embout renforçateur est auto-centreur. Il est destiné à la protection des tuyaux, canalisations ou autres profils, afin obtenir sur le parement interne du conduit, sans solution de continuité, une protection continue sans que la soudure provoque la destruction de ce revêtement sur le secteur traité.
