What Are Tubular Heaters?

Tubular heaters are typically made using steel, stainless steel, Incoloy, inconel or titanium alloys. Tubular heating elements are often regarded as the foundation of all heating elements. These heating elements have a strong outer sheath to help protect the process heater from physical stress and uses high quality alloys to allow efficient heat transfer from resistance coil to your heating medium.

Tubular heaters function as cylindrical heating elements which provide thermal energy through conduction, convection, and radiation methods according to specific usage requirements. The system operates through its durable design, which maintains operational efficiency under extreme working conditions, while its material composition enables effective heat transfer between various substances.

Applications of Tubular Heaters

Tubular heaters serve multiple industrial sectors which demand precise and continuous heating of liquids and gases and solid materials. The equipment’s adaptable design permits operation in various environmental conditions while supporting multiple heating techniques.
