Conduit system e.g. double wall hose assembly, for use in e.g. diesel engine, has inner conduit, where current is applied at two pairs of electrical conduits, such that inner conduit is heated by warming electrical conduits

摘要

The conduit system has an inner conduit (2), through which the fluid flows. Two pairs of electrical conduits (6, 7) are attached to the inner conduit in their longitudinal direction, and are connected with one another to form closed conduits, respectively. Current is applied at the pair of electrical conduits (6) and/or at the pair of the electrical conduits (7), in such a manner that the inner conduit is heated by warming the electrical conduits.
