A tubular conduit (1 ) comprising: a tubular portion (2) made from a flexible material. There is an external helical formation (7) extending around the exterior of, and parallel to the axis of, the tubular portion (2) and defining a first region of the tubular portion (2). The external helical formation (7) is for supporting the tubular portion (2). There is also an internal helical formation (10), protruding inwardly of the interior of the tubular portion (2) and extending parallel to the axis of the tubular portion (2) and defining a second region of the tubular portion (2). The internal helical formation (10) is for imparting helical flow on fluid passing through the tubular portion (2). The first region does not extend throughout the second region.
