conductive corrugated tubing including convolutions of peaks and valleys; a conductive polymer jacket disposed along a length of said corrugated tubing.
- 2. The tubing assembly of claim 1 wherein:
said corrugated tubing is annular.
- 3. The tubing assembly of claim 1 wherein:
said corrugated tubing is helical.
- 4. The tubing assembly of claim 1 wherein:
said polymer jacket is a thermoplastic polymer.
- 5. The tubing assembly of claim 4 wherein:
said thermoplastic polymer is a polyether-based polyurethane.
- 6. The tubing assembly of claim 4 wherein:
said thermoplastic polymer is a polyethylene.
- 7. The tubing assembly of claim 4 wherein:
said thermoplastic polymer has a minimum tensile strength of about 4000 psi.
- 8. The tubing assembly of claim 4 wherein said thermoplastic polymer has a minimum elongation of about 300%.
- 9. The tubing assembly of claim 4 wherein:
said thermoplastic polymer has a minimum flexural modulus of about 25,000 psi.
