Abstract

Un exemple d'un procédé de réparation d'un tube est décrit. Le procédé comprend la congélation d'une partie d'un tube qui contient un liquide à un emplacement, la congélation solidifiant au moins une partie du liquide. Le procédé comprend également la division du tube au niveau de l'emplacement, ce qui permet d'obtenir deux sections fendues du tube. Le procédé comprend en outre le raccordement des deux sections fendues du tube.
