Applications Versatile tubular elements can be designed for use in most applications. See guidelines in the Tubular Heater Overview section. Advantages 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.

Features 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 bending inside radius is 1-1/8". See bending requirements in the Tubular Heater Overview section.
