SCOPE
Reasons for Corrosion Inspection and Monitoring
- Obtain information to enable a corrosion audit to be carried out on the state of operational equipment
- Obtain information on the interrelation between corrosion rates and process or operating variables
- Obtain information on the corrosion mechanisms or kinetics of degradation
- Assess material or inhibitor reactions
- Prove operational reliability
- Check on the status of cathodic protection, condition of coatings or other corrosion control measures
