ABSTRACT:
A heat trace assembly for heating a conduit is provided that comprises at least one preformed heat trace section adapted to be placed around at least a portion of the conduit and a connector secured to the heat trace section. The connector is adapted for coupling the heat trace section to an adjacent heat trace section, and the heat trace section and the connector have mating mechanical features to allow the heat trace section to be quickly connected to and disconnected from the conduit. Additionally, a heat trace junction is provided that preferably defines a cross configuration and comprises a plurality of arms extending from a central portion of the heat trace junction. The plurality of arms are deformable to conform to a junction within a conduit system. Thermal insulation jacket configurations are also provided in accordance with several embodiments of the present invention.
