-14- TITLE OF THE INVENTION: Small Diameter Radiant Tube Heater ABSTRACT Small portable electrical resistance heated radiant heating unit useful for insertion in tube bores to effect localized high temperature heating. Useful for the internal heating of tubes and tube/sleeve assemblies in steam generators, for brazing, stress relieving, and other applications. Has a machined mandrel of boron nitride and electrical resistance wire leads that have reduced electrical resistance for reduced heat generation by the leads. The leads preferably are braided, to permit the use of cramped connectors.
