SUMMARY

The optimal method for heating copper tubing using nichrome wire involves wrapping the copper tube with ceramic paper or thin ceramic cloth, followed by tightly coiling nichrome wire around it. This assembly should be secured with layers of ceramic insulation and standard steel wire. It is crucial to ensure that the nichrome wire maintains tight contact with the copper tubing while being insulated adequately to prevent harmful emissions. Alumina ceramic paper is recommended as a suitable insulating material.

PREREQUISITES
  • Understanding of nichrome wire properties and applications
  • Knowledge of thermal insulation materials, specifically alumina ceramic paper
  • Familiarity with electrical voltage considerations, specifically 10 volts
  • Basic skills in assembling heating elements and insulation techniques
NEXT STEPS
  • Research the thermal conductivity and insulation properties of alumina ceramic paper
  • Explore the expansion characteristics of nichrome wire when heated
  • Learn about safe handling and assembly techniques for high-temperature applications
  • Investigate alternative insulating materials that can withstand high temperatures without emitting harmful vapors
USEFUL FOR

This discussion is beneficial for electrical engineers, DIY enthusiasts, and anyone involved in heating element design or thermal management of metal components.

Voltage is 10

I'd probably get some ceramic paper or thin ceramic cloth and wrap the Cu tube with it, then wrap nichrome around both with many turns. I would then wrap this with many layers of ceramic paper or cloth and keep it all together with standard steel wire twisted upon itself. The nichrome should be in tight contact with the pipe, with the ceramic paper between them. Any other insulator should work, assuming it will survive contact with red hot nichrome and does not emit harmful vapors. Google alumina ceramic paper and go from there.

Note also that the nichrome will expand when heated and may not stay tight on the ceramic paper...
 
Wow that's a really good idea thank you.
