What would be the best method for heating copper tubing via nichrome?

Click For Summary

Discussion Overview

The discussion revolves around the best method for heating copper tubing using nichrome wire, focusing on practical approaches and materials for insulation and wrapping techniques. The context includes experimental application and technical reasoning.

Discussion Character

  • Exploratory, Technical explanation, Experimental/applied

Main Points Raised

  • One participant suggests wrapping the copper tube with ceramic paper or thin ceramic cloth, then wrapping nichrome wire around both, ensuring tight contact with the pipe.
  • Another participant emphasizes the importance of using an insulator that can withstand high temperatures and does not emit harmful vapors, recommending alumina ceramic paper.
  • A participant notes that nichrome wire will expand when heated, which may affect its tightness against the ceramic paper.
  • A later reply expresses appreciation for the proposed method, indicating a positive reception of the idea.

Areas of Agreement / Disagreement

Participants appear to agree on the general approach of using ceramic materials for insulation and the wrapping technique, but there is no consensus on specific methods or materials beyond the initial suggestions.

Contextual Notes

Considerations include the thermal expansion of nichrome and the need for insulation that can withstand high temperatures without harmful emissions. Specific properties of materials and their interactions under heat are not fully explored.

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.
