Title (EN) THE METHOD OF REPAIR FROM INSIDE OF LARGE DIAMETER PIPES
(FR) PROCÉDÉ DE RÉPARATION À PARTIR DE L'INTÉRIEUR DE TUYAUX DE GRAND DIAMÈTRE
Abstract:
(EN) The method relates to internal lining of tubes through the insertion of two pigs, between which a curing material is inserted, said pigs are connected through a cylinder which forces the particles of the curing material towards the inner surface of the tube, thus providing efficient repair from inside.
(FR) L'invention concerne un procédé se rapportant à un revêtement interne de tubes par l'insertion de deux racleurs, entre lesquels un matériau de durcissement est inséré, lesdits racleurs sont reliés par l'intermédiaire d'un cylindre qui force les particules du matériau de durcissement vers la surface interne du tube, assurant ainsi une réparation efficace à partir de l'intérieur.
