Straight Type Flexible Electric Tubular Heater
ndustrial tubular heating elements are highly adaptable to most applications where electrical heating is required. They can be used in their straight form or bent into various shapes.
Watt Density & Sheath Material:
The two most critical factors that affect the durability of a tubular heater are:
1. Sheath material
2. Watt density
The sheath material type of a tubular heater depends on the operating temperature and the corrosivity of the medium within which the heater will operate. The watt density distribution on the surface of a tubular heater is critical for two reasons. First it determines the temperature that a heating element sheath will attain within the conditions that the heater is subjected to. The second reason is that every material has a specific maximum watt density that it can tolerate during its heating cycle.
Forming Tubular Elements:
The MgO insulation used in tubular heating elements is compacted by reducing the element diameter in a roll reducing mill. The elements are then annealed in a controlled atmosphere furnace to relieve the metal stressing (work hardening) that takes place during the rolling to size reduction of the sheath. Annealing brings the metal back to a soft state, allowing the element to be bent into virtually any configuration. However, since forming also work hardens the metal, some precautions must be observed in order to prevent the sheath from breaking during bending or developing stress cracking marks.

Single- and double-ended tubular heater element lend themselves to virtually the entire range of immersion and air heating applications. They have a variety of mounting and termination options that make them ideal for industrial applications. JAYE uses high quality nickel-chrome wire to deliver an even heat distribution to the element sheath. High purity, grade A magnesium oxide is used as the internal insulation to insure the best thermal transfer and insulation resistance. A variety of electrical terminations, mounting fittings and brackets, along with the wide array of bending options, allow for easy integration into any heating system.
Usual Applications:
1. Forced air heating
2. Thermal forming machines
3. Direct immersion in liquids
4. Comfort radiant heaters
