TEC Splice Kit
A kit that joins two lengths of TEC, or the TEC to the gauge lead, restoring the conductor and the metal pressure barrier across the joint.
What it does
Makes the joint as strong as the cable itself, so a long string or a repair does not become the weak point of the monitoring system. Used on PCP and other artificial lift wells.
Basics
| Seal | Metal to metal |
| Materials | 17-4PH, Alloy 625 or Alloy C-276 |
| Rating | 20,000 psi external, 10,000 psi test |
| Temperature | Up to 150 °C |
Common failures
- Splice made without following the kit procedure
- No pressure or continuity test after making the splice
Troubleshooting
- Symptom
- Insulation drops right after a splice
- Likely cause
- Moisture or contamination in the joint, poor crimp
- What to check
- Remake following the kit steps: crimp, cure, pressure and continuity test
- Symptom
- Signal fine at surface test but lost downhole
- Likely cause
- Splice seal not holding under well pressure
- What to check
- Pressure test each splice before running
