Ultrasonic Thickness Gauging (UTG)
Ultrasonic Thickness Gauging (UTG)
Ultrasonic Thickness Gauging (UTG) is a non-destructive testing method used to measure the thickness of materials, primarily metals, by transmitting ultrasonic waves through the material and analyzing the time it takes for the waves to travel through it. UTG is commonly employed in various industries to assess the thickness of pipes, tanks, vessels, and structural components, ensuring their structural integrity and safety.
Applications of Ultrasonic Thickness Gauging :
- Corrosion Monitoring: UTG is widely used for monitoring corrosion and erosion in metal structures, such as pipelines, tanks, and pressure vessels, by regularly measuring the thickness of the material and identifying areas of thinning or degradation.
- Pipeline Inspection: UTG is employed for inspecting the thickness of pipeline walls, detecting areas of corrosion, wear, or damage that may compromise the integrity of the pipeline
- Tank Inspection: UTG is used for assessing the thickness of tank walls, including above-ground storage tanks (ASTs) and underground storage tanks (USTs
- Structural Integrity Assessment: UTG is utilized for evaluating the thickness of structural components, such as beams, columns, and plates, to ensure their structural integrity and safety.
Advantages of Ultrasonic Thickness Gauging :
- Accuracy: UTG provides precise measurements of material thickness with high accuracy. It can detect even small variations in thickness, allowing for precise assessment of material integrity.
- Wide Range of Applications
- Portability: Ultrasonic thickness gauges are often portable, allowing for on-site measurements in various locations.
- High Penetration Depth: Ultrasonic waves used in UTG can penetrate deep into the material, allowing for the measurement of thickness through coatings, paints, and surface treatments. This capability ensures accurate measurements in challenging environments.
