Working, Types And Varied Applications Of Tubular Heating Elements

Human beings living or working in chilly areas wish to enjoy sufficient warmth for which electric heaters are greatly helpful. As contrast to other heating component; a tubular heater consumes less energy.

Quite durable, these heaters are used in variety of  applications including heating gases, liquids, solids and other things.

Designing – Tubular heaters are made by considering precision as the key feature. Uniform thermal profile is facilitated with the helical wound nickel-chromium that offers big resistance. Strong connection for enhanced life of the heater is ensured with circumferential cold pin-to-wire fusion since welded together. Resistance wire life at high temperatures is ensured with compacted, high purity MgO dielectric insulation. This heater is capable to facilitate safe and protected performance because of the UL and CSA recognized components

Working – Transfer of heat with a tubular heater is ensured with the help of direct exposure to gas, solid or liquid that is configured to a particular size, watt density, sheaths and shapes. Temperature equal to 750 degrees C or at higher levels is reached with perfect configuration.
 
Types – Tubular heating elements may be classified into the following categories:

  1. Singular tubular elements – Made with a mineral insulated alloy sheath, these heaters are capable to prevent vibration and splashing. Longer service is the exclusive feature of these heaters.
  2. Double tubular element – It involves two series wired heating components.
  3. Hairpin tubular element – Mostly used for moisturized environment, this type of component is available with resistant terminal housing.
Other types of tubular heaters include the straight tubular heating element with standard diameters including .260", .315", .375", .430", .496", and .625". Another major type is the formed tubular heating element that is designed into the fitting configuration and sheathed in different substances. Availability of components may determine the termination or connection. The manifold type of such heating equipment facilitates reliable heating sources with precision fit optimization of heat transfer to the surface.

Applications – Tubular heaters may be used for industrial conduction heating wherein transfer of heat from the outer sheath travels to the desired areas in reliable manners. Use of steel in this application ensures excellent transfer of heat. Industrial convection heating is another big benefit of the tubular heaters that are able to heat the surrounding air in reliable manners. Dissipation of heat is ensured with quick speed. Moreover rapid heat penetration is another big benefit. This application does not involve any motor or fan. Silence and low maintenance is the unequalled benefit of this application.

Industrial radiation heating is another significant application as regards the tubular heating elements. It involves generation and radiation of heat over specific areas. Reflectors are placed at the particular angles that ensure efficient direction as regards transfer of heat. Tubular elements are preferred for this industrial radiation heating application. It is generally used in mining, oil, gas, automotive, medical, construction, thermoforming and manufacturing enterprises.

Candidly, a tubular heater can be utilized for different gainful purposes. Precision, compact size and availability in different shapes are its amazing features that have enhanced its demand and popularity across the globe.
