(FR) RACLEUR D'OLÉODUC DOTÉ D'AILETTES
Abstract
(EN)
A pipeline pig has a nose, a central section having a central axis, a plurality of fins extending rearwardly from the central section, each of the plurality of fins having a pressure responsive scraping end; the scraping ends of the plurality of fins collectively define a circular scraping surface extending radially outwardly from the central axis of the central section; each of the fins having inward facing pressure bearing surfaces; and at least a flow-through passage extending between the fins.
(FR)
L'invention porte sur un racleur d'oléoduc, lequel racleur comporte un nez, une section centrale ayant un axe central, une pluralité d'ailettes s'étendant vers l'arrière à partir de la section centrale, chacune de la pluralité d'ailettes ayant une extrémité de raclage réagissant à la pression ; les extrémités de raclage de la pluralité d'ailettes définissant collectivement une surface de raclage circulaire s'étendant radialement vers l'extérieur à partir de l'axe central de la section centrale ; chacune des ailettes ayant des surfaces de portée de pression dirigées vers l'intérieur ; et au moins un passage d'écoulement traversant s'étendant entre les ailettes.
