Abstract
A fluid conduit body having a semi-conductive material disposed therein and at least one wire coupling an electrical power supply to the conduit to provide an electrical current therethrough to heat the fluid conduit also has an end cover molded over a fitting fitted to an end of the conduit and over an end of the wire coupling the power supply to an end of the conduit. Alternatively, a fluid conduit heating system employs a semi-conductive sleeve disposed over a fluid conduit with the sleeve extending at least partially over a fitting fitted to an end of the conduit. An electrical power supply is coupled to each end of the sleeve to provide an electrical current through the semi-conductive sleeve to heat the sleeve and the fluid conduit. An end cover is molded over at least a portion of the fitting and the sleeve extending thereover.
