Abstract

Racleur instrumenté pour l’inspection de canalisations de pipelines. L'invention concerne un racleur instrumenté dans lequel est installé un dispositif permettant de détecter et de localiser, une fuite ou un soutirage clandestin d’hydrocarbure dans un pipeline. Ce dispositif est agencé de telle sorte à ménager dans le racleur, une chambre de mesure étanche appelée volume référent, délimité d’une part, aux extrémités du racleur, par deux coupelles d’étanchéité et, d’autre part, par la paroi interne de la canalisation, dans lequel la pression est mesurée et comparée à la pression de référence correspondant à la pression à laquelle circule le fluide à l’intérieur de la canalisation ; une variation négative de pression dans ce volume référent signe la présence d’une perte de produit soutirage clandestin et/ou fuite. D’autres variations de pression, enregistrées et corrélées aux documents de profil de la ligne (carnet de soudure et autres), permettent en outre sa localisation rapide. Ce dispositif permet de répondre aux problématiques de vol de produit en ligne auxquelles les exploitants de pipeline sont aujourd’hui confrontés.
