Patent

CA 2603745

An apparatus and method for pressure testing one or more sections of a pipeline are provided. In at least one embodiment, the apparatus includes a first high pressure seal and a second high pressure seal adapted to isolate a test volume located within a section of the pipeline between the first and second high pressure seals. The apparatus also includes at least one flexible member connecting the first high pressure seal to the second high pressure seal, the at least one flexible member adapted to permit movement of the first high pressure seal relative to the second high pressure seal, allowing the apparatus to travel through a curvature in the pipeline.

L'invention concerne un appareil et un procédé permettant de tester une ou plusieurs sections de canalisation. Dans au moins un mode de réalisation, l'appareil comprend un premier joint d'étanchéité haute pression et un deuxième joint d'étanchéité haute pression adaptés pour isoler un volume d'essai situé à l'intérieur d'une section de la canalisation entre le premier et le deuxième joint d'étanchéité haute pression. L'appareil comprend également au moins un élément flexible reliant le premier joint d'étanchéité haute pression au deuxième joint d'étanchéité haute pression, ledit élément flexible étant adapté pour permettre le mouvement du premier joint d'étanchéité haute pression par rapport au deuxième joint d'étanchéité haute pression, ce qui permet à l'appareil de se déplacer à travers une courbure de la canalisation.
