ABSTRACT:
Electric heating elements, particularly adapted for use in solder pots or in other uses wherein a substance is to be maintained in a molten or plastic condition, and commonly termed in such uses as over-the-side heaters. A conventional tubular heater is disposed within the central opening of a thick-wall metal pipe or tube, and the latter is swaged to reduce its cross-sectional size and thereby fit tightly about the tubular heater. Thereafter, the pipe and the heater therein, are bent in a pipe bender to any desired shape.
