Tubular heating element are used for almost every kind of heating appliances. They are easy to form and feature highest mechanic stability and electric properties at the same time.
Even though Tubular heating element are technically rather mature and universal to use, there exist various new innovative solutions for many applications.
Screw in Tubular heating element are standardised for use in liquids like water.
Tubular heating element are easy to install,control and maintain, unique designer as your requirement. For corrosive enviroment, titanium material or tubular heating elements with additional teflon sleeving are available .
1.Tube diameter: Φ2mm-Φ30mm
2.Tube Material: Fe, SS304;SS316,SS321,ss202 etc
3. Insulation Material:High-purity Mgo
4. Reisistance wire element:Ni-Cr or FeCr
5. Lead Connection Option: Crimped or Swaged leads
6.Lead and type of connection leads, 10″ Fiberglass Standard(Wire options,silicone high temperature frberglass).
7. The voltage and power can customized
8. The shape of tubular heater can be customized according to your drawing
In applications where tubular heaters are exposed to forced convection, placing fins around tubular heaters increases their surface area and thus improves their heat transferring capacity. Finned tubular heaters, compared to regular tubular heaters, run at lower surface temperatures for the same watt densities when placed in identical air streams.
