Flexible tubular conduit with heating means and stiffening means for transporting pressurized fluids

摘要: A tubular conduit for the transport of fluids under pressure includes a flexible outer sheath, group stiffening reinforcements, inner sheath or tube, and if applicable at least one intermediate heater in form electrically conductive wires, connected to an electric power source releasing heat by Joule effect, said wires being arranged on length conduit. Also plurality are layer which parallel another spirally wound around axis conduit, layers placed between two sheaths noncontiguous each resting surface contact underlying sheath.
