Even/Uneven Wear Track
| EVEN WEAR TRACK | UNEVEN WEAR TRACK |
SYMPTOMS:
- Even/uneven wear track
CAUSES:
- Even wear on a seal face usually indicates good contact between the mating seal rings
- Uneven wear on a seal face indicates:
- Distortion of the seal ring due to over tightening, clamping, or excessive pressure
- Distortion due to insufficient gland support
- Misaligned seal rings in a split seal
- Improperly stress relieved component
FAILURE MODES:
- Misinstallation
- Quality/design related issue
SOLUTIONS:
- Review installation techniques/instructions
- Check/reduce torque and evenly tighten gland bolts
- Review operating conditions
- Reduce torque and evenly tighten gland bolts
