Ultrasonic Testing (UT)
Ultrasonic Testing (UT) is a powerful Non-Destructive Testing method used to examine materials for internal discontinuities and measure material thickness without damaging the component.
Looking Beneath the Surface
At KLASIC Oil Inspection Services Limited, we provide ultrasonic inspection services for equipment and components across the oil & gas, marine, petrochemical, power and industrial sectors.
UT uses high-frequency sound waves introduced into the material to identify changes in acoustic response associated with discontinuities or changes in material geometry.
OUR ULTRASONIC TESTING CAPABILITIES
Our UT services can support:
- Thickness measurement
- Weld examination
- Corrosion assessment
- Wall thickness monitoring
- Internal discontinuity detection
- Lamination assessment
- Material condition assessment
- Remaining wall thickness determination
TYPICAL APPLICATIONS
UT can be applied to:
- Pipelines
- Pressure vessels
- Storage tanks
- Process piping
- Structural components
- Welded joints
- Pressure-containing equipment
- Marine structures
- Wellhead components
- Steel plates and fabricated components
CORROSION & THICKNESS ASSESSMENT
One of the most common applications of UT is the measurement of material thickness.
Repeated thickness measurements can help establish whether an asset is experiencing material loss or deterioration and can provide valuable information for corrosion monitoring and maintenance planning.
Where historical inspection data is available, UT results can also contribute to the assessment of corrosion rates and remaining material thickness.
WELD INSPECTION
Ultrasonic Testing can be used to examine welds for internal discontinuities that may not be visible from the surface.
Depending on the application, UT can assist in identifying indications associated with conditions such as:
- Lack of fusion
- Lack of penetration
- Cracks
- Slag inclusions
- Internal porosity
- Other relevant internal discontinuities
Where a more detailed ultrasonic examination is required, KLASIC can also deploy advanced ultrasonic techniques such as PAUT and TOFD.
WHY KLASIC?
We combine appropriate ultrasonic equipment, competent personnel, controlled inspection procedures and reliable reporting to provide clients with dependable information about material and component condition.
Our UT services can support both routine inspection programmes and targeted integrity assessments.
