What are Tubular Heating Elements?

Tubular heating elements are a widely-used type of heating element that may be bent into standard or unique shapes to match a specific purpose.

The popularity of tubular heaters is largely due to their adaptability. To heat liquids, air, gasses, and surfaces, tubular heating elements provide excellent heat transmission through conduction, convection, or radiation.

The majority of heater assemblies use tubular elements in a variety of shapes, including round, triangular, flat press, and shaped.

How Tubular Heating Elements Work

Electricity is converted into heat with the use of heating components. First, conductors are efficient electrical transporters. Insulators, on the other hand, make poor electricity transporters.

Resistors are a component of electronic circuits that regulate current flow. Although in varying degrees, conductors and insulators both offer resistance to electric currents that pass through them. Insulators provide a high level of resistance, while conductors provide a low level.

In other words, when electricity passes through a resistor, it produces heat energy, which is how it functions. But not just resistors carry out this function. When applying enough electrical force to a wire, it will become hot even if it is very thin.

Incandescent bulbs (old-fashioned, bulb-shaped lights) operate on this fundamental principle. A filament is an extremely small coil of wire that is located inside the glass bulb. It creates light by creating heat when enough power goes through it since it flashes white hot and extremely brightly.

Heating elements thus offer a reliable electrical component that emits heat when a strong electric current passes through it.

Tubular Heating Element Design Considerations

A tubular heater's composition and matching with other components need to be carefully considered in order to guarantee performance optimization and safety. For instance, explosion-resistant tube heaters are frequently employed to deliver heat close to explosive objects. This makes sure that the heating element won't make the issue worse in the event of an unintentional ignition during heating. Other controls and safety features, such as independent timing controls, overheat protection, internal temperature sensors, and other security measures, can also be included.

To increase heat generation capacity and prevent unintentional contact with dangers like leaking oils or grease, tubular heaters used in ovens are frequently insulated with a ceramic substance like silicon carbide. As a result, there are fewer chances of inadvertent ignition.

Fluoropolymers, other metals like iron and nickel alloys, polyimides, and even synthetic rubber are common insulation materials. Tubular heating elements can be used in a wider variety of applications than most other heating element variations due to the versatility of tubular heaters and the extensive customization choices accessible to their customers.

Applications of Tubular Heaters

  • Reflectors are frequently used in tubular heaters for radiant heating in order to focus heat energy on the area that needs to be heated. Applications involving warming, drying, and curing work well with this. Watt density should be reduced by 20% to 30% compared to air heating since the main method of heat transfer when utilizing heaters in a vacuum is radiation. Vacuum feedthrough setups frequently use heaters with an aluminum or Inconel sheath.
  • They can be used as immersion heaters and heat sources that transfer heat directly or through the air. Tubular heaters are widely used in business, industry, and consumer items because of their adaptability. Although not all coil heaters are tubular, tubular heaters are sometimes referred to as coil heaters.
  • Consumer, business, and industrial ovens and dryers, dishwashing machines, space heaters, and a wide range of other devices and appliances all use tubular heating coils. To increase their ability to generate heat and to shield the heating element from dangers, they are occasionally covered with ceramic insulation. Typically, a protective covering and an interior conductive substance make up tubular heating components. Nickel, steel, aluminum, copper, brass, and other metals that are both electrically and thermally conductive are a few of these materials.
  • When it comes to heating water, oil, and grease, a number of businesses, from retail food to residential buildings, use copper-sheathed tube heaters. On the other hand, the stainless steel type is perfect for use in commercial applications that call for the use of powerful acids and bases. In the most corrosive situations, titanium sheaths are employed.
