摘要： The present invention relates to an unbonded flexible pipe having a length and a longitudinal axis and comprising, from the inside and out, a carcass made from an electrically conductive material, an internal pressure sheath made from an extruded polymer, at least one external armour layer and an outer sheath, in which the carcass is adapted for connection to an electric power source for conducting an electric current. Moreover, at least a part of the external armour layer is electrically conductive, the carcass and the external armour layer allowing a difference in electric potential to be established partly or fully over the internal pressure sheath, wherein the internal pressure sheath is partly or fully covered by a conforming cover layer made from a material which is electrically conductive and has a bulk resistance larger than the specific resistance of the electrically conductive material of the carcass.

摘要： A fluid conduit that is below grade or under water is separated from ambient water by a confined layer of liquid that may be largely undivided by solids. The separation distance between the liquid containment means and the piping or pipeline is such that the total heat transfer by natural convection and conduction from the piping or pipeline to the water containing environment is kept within limits thought necessary to adequately insulate the contents of the pipeline. A liquid may be pumped between the pipe and the means for containing the insulation so as to displace fluids from a pipeline or a heated liquid may be pumped through that space to warm the contents of the pipeline. If the insulating liquid also electrically insulates the pipe, then the pipe may be heated by passing a current directly through the pipe.
