How does NDT thickness measurement work?
NDT thickness measurement is commonly performed using Ultrasonic Thickness Testing (UTT), which uses high-frequency sound waves to measure the thickness of materials without cutting, dismantling, or damaging the equipment. The ultrasonic probe sends sound waves into the material, and the time taken for the waves to reflect back from the opposite surface is used to calculate the material thickness.
This method is widely used to detect corrosion, erosion, and material thinning in equipment and structures
that may weaken over time.
Where Thickness Measurement is Commonly Used
- Pressure vessels and storage tanks
- Pipelines and piping systems
- Boilers and heat exchangers
- Structural steel components
- Marine and offshore equipment
- Industrial machinery and fabricated structures
Benefits of NDT Thickness Measurement
- Detects corrosion and thinning without shutdown
- Helps assess remaining life of equipment
- Prevents leaks and structural failures
- Supports preventive maintenance planning
- Reduces downtime and repair costs
In India, thickness measurement is conducted as part of safety inspections in accordance with requirements under the Factories Act, 1948, standards from the Bureau of Indian Standards, and guidelines issued by the Directorate of Industrial Safety and Health.
At Uniquo, NDT thickness measurement is performed using calibrated ultrasonic equipment by trained professionals to ensure accurate, reliable, and compliant inspection results.
