Patent
CA 2433498
There is disclosed a method and a device to allow a "rigid" pig to pass into an undersea flow pipe in which a hollow flow-constricting device is in use. According to the invention the device is provided with a first pipe branch and a second pipe branch. The first pipe branch is provided with a hollow flow- constricting device in it and both first and second pipe branches are provided with shut-off valves, whereby the flow can be diverted to the second pipe branch thereby enabling a rigid pig to pass into such second pipe branch, when necessary.
L'invention concerne un procédé et un dispositif permettant à un racleur <= rigide >= de passer dans un conduit d'écoulement sous-marin dans lequel fonctionne un dispositif creux d'étranglement de l'écoulement. Selon l'invention, le dispositif est muni d'une première et une seconde ramification de conduit. La première ramification de conduit renferme un dispositif creux d'étranglement de l'écoulement et les deux ramifications sont équipées de robinets de sectionnement, l'écoulement pouvant ainsi être dévié vers la seconde ramification et le racleur rigide passer dans cette seconde ramification, si nécessaire.
