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 4 Terminals — Standard. Integral parts
of the element are of high strength to resist
bending during tightening of the wiring connections.
Type 4 is threaded extension of 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 1-1/2". See bending requirements
in the Tubular Heater Overview section.
