ABSTRACT:
A flexible conduit has an undulating liquid tight inner tube portion and layers of metal reinforcing wound around the tube. The layers include a burst resisting layer adjacent the tube, then traction and pressure resisting layers, and an outer sheath. The undulations in the interior of the tube can be filled with packing or the tube can be lined with a spiral strip to lessen resistance to fluid flow through the conduit.
