Abstract
(EN)
The present invention relates to the repair of pipes, comprising a two-part ring fixed initially by a compression unit which allows the execution of longitudinal welding in order definitively to fix the two-part ring, via apertures, before the compression unit is removed. The two-part ring will be completely welded to the pipe, especially in regions close to connections, but it is necessary for the two-part ring to be fixed initially by the compression unit for the purpose of shaping and definitive geometry of the ring relative to the pipe, normalization of fluid conveyance and in order that it is possible for welding to be planned for the opportune moment.

La présente invention concerne un système de réparation de tubulures comprenant un anneau biparti fixé initialement par une unité de compression qui permet l’exécution du soudage longitudinal en vue d'une fixation définitive de l’anneau biparti, par l'intermédiaire de fenêtres, avant le retrait de l'unité de compression. L’anneau biparti est entièrement soudé au tube, notamment dans les zones voisines des raccords. Il est donc nécessaire que l’anneau biparti soit fixé initialement par l’unité de compression en vue d’une formation et d’une géométrie définitive de l’anneau sur le tube, pour une normalisation du transport de fluides et pour que le soudage puisse être planifié au moment opportun.

A presente invenção refere se ao reparo de tubulações que compreende um anel bipartido fixado inicialmente por uma unidade de compressão que permite a execução da soldagem longitudinal para fixar definitivamente o anel bipartido, através de janelas, antes que a unidade de compressão seja retirada. O anel bipartido será soldado completamente ao tubo, em especial nas regiões próximas as conexões, porém é necessário que o anel bipartido seja fixado inicialmente pela unidade de compressão para conformação e geometria definitiva do anel ao tubo, normalização do transporte de fluidos e para que a soldagem possa ser planejada para o momento oportuno.
