An adjustable swage features an ability to enhance a radial collapse force when an obstruction in a tubular is encountered to allow radial contraction so that the obstruction can be cleared. The movable segments are configured to elastically bend on high loading so as to create additional radial component force to aid the adjustable swage in reducing its size to clear the obstruction.
L'invention concerne un redresse-tubes réglable ayant une capacité d'améliorer une force d'écrasement radiale quand une obstruction est rencontrée dans un tube pour permettre une contraction radiale de manière à dégager l'obstruction. Les segments mobiles sont configurés pour se plier de manière élastique lors d'un chargement élevé pour créer une force composante radiale supplémentaire aidant le redresse-tubes réglable à réduire sa taille afin de dégager l'obstruction.
