High temperature corrosion mapping and weld inspections

Non Destructive Testing capability up to 500°C (932F)

To reduce turnaround time and to increase plant availability, high temperature corrosion mapping and weld inspection capability with advanced ultrasound techniques is available for inspections up to 485 °C (905F) when the plant is online.

The technology is standardized and ready to go for inspections up to 350 °C (662F). Above this temperature, preparation time will take from a few hours to a few days.

Inspection of partly filled “golden” welds at pre-heat temperature can avoid extension of your turnaround.

High temperature non-intrusive inspections are part of the Minimum Intervention Strategy for Inspection (MISI) concept to reduce turnaround duration further.
