Tubing or piping for carrying a multiphase flow is provided with means for inducing swirl flow, such that the denser components of the flow tend to the outer wall of the tubing or piping, and less dense components tend to the centre of the tubing or piping. The flow thus exhibits a "centrifuge" effect, which prevents lighter or heavier components of the flow from accumulating in upper or lower regions respectively of the tubing or piping, and reduces the risk of airlocks and the like. Preferably, the tubing or piping is in the form of a helix, which may be a low amplitude helix.
L'invention concerne une tuyauterie ou une canalisation servant à acheminer un écoulement polyphasique, dotée d'un moyen d'induire un écoulement turbulent, de sorte que les composants plus denses de l'écoulement s'orientent vers la paroi extérieure de la tuyauterie ou canalisation, et les composants moins denses s'orientent vers le centre de la tuyauterie ou canalisation. L'écoulement présente ainsi un effet "centrifuge" qui empêche les composants plus légers ou plus lourds de l'écoulement de s'accumuler dans des zones supérieures ou inférieures, respectivement, de la tuyauterie ou canalisation, et diminue le risque d'un effet poche d'air ou analogue. De préférence, la tuyauterie ou canalisation se présente sous la forme d'un hélice, lequel peut être un hélice de faible amplitude.
