The crack on the titanium tubes which is the surface of condenser, was found during the commissioning.
There are a few causes of tube damage which may occur by one or more combined mechanisms during operation as below.
- Erosion at steam side
- Damage by impact
- Condensate corrosion
- Stress corrosion cracking at steam side
- Fretting and fretting corrosion from tube vibration
- Tube impact damage from tube vibration
Fatigue and corrosion fatigue from tube vibration
