Abstract

Systems, apparatus and methods are described where a heater is arranged adjacent to a pipe make/break vise assembly to heat a female tool joint of two pipe sections connected by threads to facilitate breaking or disconnection of the joint. The heater can have any configuration or can be used in any manner to result in even heating around the circumference of the female tool joint. In addition, the heater can be incorporated into the same apparatus as the make/break vise assembly, or the heater can be an apparatus that is separate from the apparatus containing the make/break vise assembly. In one embodiment, the heater can be used as a stand-alone heater to heat the female tool joint.
