Heated fluid conduits, systems and methods

摘要

A heated fluid conduit has a body with a semi-conductive material disposed therein with an electrical power supply coupled to the conduit to provide a voltage across the conduit and a current therethrough, heating the fluid conduit. A fluid conduit heating system comprises a semiconductive sleeve disposed over a fluid conduit and an electrical power supply coupled to the ends of the sleeve to provide a voltage across the sleeve and a resulting current through the semiconductive sleeve, heating the sleeve and conduit Alternatively, one terminal of the electrical power supply is coupled to each end of the sleeve or conduit, and another terminal of the electrical power supply is coupled to the sleeve or conduit therebetween, to provide parallel heating circuits.
