The metal sheath isolates and protects the
resistor wire from the environment. At the
same time it maximizes heat transfer capability
to the work. Tubular elements can be bent to
put the heat where it works best.
Versatile tubular elements can be designed for
use in most applications. See guidelines in the
Tubular Heater Overview section.
Type 3 Terminals — Heliarc-welded to the
cold pin. See terminal detail drawing in the
Tubular Heater Overview section.
Work Temperatures — See Tubular
Heater Overview section.
Bending — Customer’s minimum inside bending
radius is 15/16". See bending requirements in
the Tubular Heater Overview section.
