Abstract
A wrapped heating assembly may be wrapped around a tubular member for heating the tubular member. The wrapped heating assembly includes an outer insulation sleeve and a pocketed heating system that is fixed to an inner surface of the outer insulation sleeve in a manner that forms longitudinal pockets that extend between a first end of the outer insulation sleeve and a second end of the outer insulation sleeve. One or more heater strips are each respectively inserted longitudinally into a corresponding one of the pockets, wherein heat is generated by the heater strips when electrical current flows through the heater strips for heating the tubular member in a wrapped position. Multiple wrapped heating assemblies may be daisy chained together by electrical connectors into a heating system with a single thermostat and linked to a single power source to accommodate a wide range of configurations of tubular member systems.
