Roxar FSM Log Area Corrosion Monitor™
Roxar FSM Log Area Corrosion Monitor is a non-intrusive solution that can permanently track general and localized metal loss over a pre-defined surfaces in steel pipes, bends and vessels up to 500°C (932°F).
Due to its monitoring characteristics, Roxar FSM Log is widely used in process piping and line pipes in downstream, midstream and upstream applications for asset integrity management activities and risk based inspection optimization.
