ABSTRACT:
A tubular assembly10is disclosed for passing fluids within a hydrocarbon recovery well. The tubular assembly10has an insulated connection12between insulated tubing segments14, 16. Tubing segments14, 16are connected via a threaded connection, and the resulting joint10is insulated by an external insulating sleeve18. The insulating sleeve18may have unitary construction, such that the sleeve18may only be installed or removed by first breaking apart the joint10. Alternatively, the sleeve18may comprise a plurality of arcuate partial-sleeves, which may be assembled about or removed from the completed joint10without first breaking apart the joint10.
