Abstract
An integrated heated conduit includes an inner conduit through which a fluid may be transferred. The inner conduit may also serve as a first electrical conductor, or an insulator may be provided on the outer surface of the conduit and a first electrical conductor may then be formed about the outer surface of this insulator. A polymeric, self-regulating heating element is provided on the outer surface of the first conductor. A second conductor is provided about the outer surface of the heating element to complete a current path across the heating element. The entire assembly may optionally be sheathed in an electrically and/or thermally insulating outer layer.
