Abstract
To transfer a fluid at high service temperature and pressure without the limitations of rigid tubing, a flexible tube is provided with a plurality of generally concentric tubular layers for transferring fluids. The innermost layers define a fluid flow path and provide insulation without pressure containment whereas the outermost layers provide fluid containment and resist pressure exerted by the fluid flowing through the tube. By utilizing a plurality of layers of different materials selected to have specific characteristics, the flexible tube operates at a service temperature and pressure providing a high level of energy transfer.
