ABSTRACT:
An expandable and retractable fluid conduit is disclosed for conveying fluid between a fixed point and a movable point. A plurality of rigid pipe sections are pivotally connected in end-to-end relation by swivel joints to form an articulated fluid conveying pipe. A plurality of rigid support sections are pivotally connected in end-to-end relation to form an articulated support member. The articulated pipe member and the articulated support member criss-cross, and are pivotally connected at their intersections, to form a lazy tong configuration. Universal swivel joints are provided at each end of the conduit, and means is provided to render each pipe section and each support section buoyant in underwater installations. In another embodiment of the invention, two articulated fluid conveying pipes criss-cross for pivotal connection at their intersections.
