The corrosion database provides corrosion rate data for various metals exposed to different process fluids. This comprehensive database supports corrosion allowance selection in PASS/START-PROF and enables remaining life calculations in the START-Operational Life module.
Corrosion rates depend on multiple factors:
Process fluid composition
Phase state (gas, liquid, or two-phase)
Material grade
Operating temperature
The START-Service Life module searches the database using keywords entered in the "product" field. The system matches against both "composition" and "detailed composition" fields. For example, entering "water" returns records for "water," "water vapor," and related entries.
