Patent

CA 2568450

The invention relates to a method for introducing a pig--like tool into an operating pipeline, such as a fluid pipe. According to the invention the pipeline is drilled during operation and the tool is injected into the pipeline through the drilled hole. During a corresponding tool rem-oval from the pipeline a method is provided for prerecon-naissance for the determination of a degree of contaminati-on, cleaning, surveying, inspecting, repairing, etc. of pi-pelines by means of a corresponding, pig-like tool. The invention also relates to a device and a tool permitting the performance of the inventive method. Thus, otherwise unpiggable pipelines can be worked in a cost-efficient man-ner.

La présente invention concerne un procédé pour introduire un appareil (2) de type racleur dans une conduite tubulaire (4) en fonctionnement telle qu'une conduite fluidique. Selon l'invention, la conduite tubulaire (4) est percée au cours de son fonctionnement et l'appareil (2) est inséré dans la conduite tubulaire (4) par le trou percé (4.4). Un procédé pour explorer, déterminer le degré d'encrassement, nettoyer, mesurer, inspecter, réparer ou analogue, des conduites tubulaires au moyen d'un appareil de type racleur correspondant, est obtenu suite au retrait de l'appareil de la conduite tubulaire. L'invention a également pour objet un dispositif et un appareil qui permettent la mise en oeuvre du procédé de l'invention. On peut ainsi traiter de façon économique des conduites tubulaires qui ne peuvent sinon pas être raclées.
