High Temperature Corrosion Mapping and Weld Inspections
Non destructive testing capability up to 500°C (932F)
Page last modified
November 25 2022
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
Reduction turnaround duration
Avoiding unplanned shutdowns
Online monitoring of indications
Execution of regular inspections outside shutdown
Increased plant safety
Strict safety pre-cautions
