High Temperature Corrosion Mapping and Weld Inspections
Non destructive testing capability up to 500°C (932F)
Page last modified
June 2 2023
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. High Temperature PAUT and TOFD are specialist Non Intrusive Inspection techniques, which enable the equipment to be inspected while in operation (on-stream).
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 (NII) are aimed to reduce turnaround duration and minimize risk of unplanned shutdowns.
Pro/con
