Title: DEVICES FOR HEATING SMALL-DIAMETER TUBING AND METHODS OF MAKING AND USING
Abstract:
Heating devices, systems, and methods of making and using a heating device. Such a heating device includes a tubular body having a passage therethrough, at least an inner layer surrounding the passage, and an outer layer surrounding the inner layer. The inner layer is electrically resistive and the outer layer is electrically insulating, and the passage is sized and configured to receive therethrough a tubing. The heating device further includes electrical contacts located at oppositely-disposed ends of the tubular body. The contacts are configured to functionally couple with a power source to provide an electrical current to the inner layer, such that applying an electrical current to the inner layer increases the temperature of the inner layer.
