Heated tube

This is a heating tube with a maximum thermal resistance of 400℃, which specializes in thermal insulation and heating of flowing fluid and gas similar to a heated hose. The inner tube is further lengthened out at both ends, making it possible to insert a different removable transfer tube for an easy replacement as required.

Heated tube


Heat resistance temperature: Up to 400℃ max.

*Please ask about higher temperatures.


  • Capable of thermal insulation and heating, the heat-generating layer comprises evenly-wound heating elements, thus minimizing differences in inner wall temperature distribution.
  • Customers can select tube materials to meet their working environment and conditions.
  • ‌Core tube materials such as Teflon or SUS can be selected to realize a flexible structure.
  • We can design tubes with materials and a wide range of fittings matched to applications and offer specifications to satisfy any requirements.
  • We can design tubes with flame retardant and noncombustible materials matched to conditions. In addition, we select heat retention material with high insulation performance to realize a structure that takes surface temperature into consideration.
