Ultrasonic Thickness Testing
Ultrasonic thickness testing provides non-destructive wall-thickness measurements that help identify metal loss, corrosion trends and areas requiring further assessment. Results become most useful when tied to equipment history and repeatable measurement locations.
Structured, traceable inspection work.
Before requesting this service
Gather any available equipment data plates, previous certificates, inspection reports, drawings, repair records and site access information. The required method and final scope should be confirmed against the equipment, applicable requirements and APIA's formally approved scope.
APIA must not describe itself as accredited or approved for any activity until the relevant formal approval has been granted for that exact scope.
Questions about ultrasonic thickness testing
What does ultrasonic thickness testing measure?
It measures remaining material thickness using sound waves without cutting into the equipment.
Can UT detect all defects?
No. Thickness measurement is primarily used for wall-loss assessment. Other defect types may require additional NDT methods.
How often should thickness readings be repeated?
Intervals should be based on equipment condition, corrosion mechanisms, previous readings, risk and applicable inspection requirements.
