Ultrasonic Thickness Measurement (UTM-Services) is a non-destructive testing (NDT) technique used to measure the thickness of materials such as metal, composites, and plastics. It utilizes high-frequency sound waves to determine the internal structure and integrity of an object without causing any damage.

How It Works

  1. Probe Contact – A transducer sends ultrasonic waves into the material.
  2. Wave Reflection – The waves travel through the material and reflect back from the opposite surface.
  3. Time Measurement – The time taken for the waves to return is analyzed to calculate the thickness.
  4. Data Interpretation – The thickness readings are displayed on a digital gauge or stored for further analysis.

Applications

  • Industrial Inspection – Used in pipelines, pressure vessels, and storage tanks.
  • Marine & Offshore – Checks corrosion and material loss in ship hulls and offshore structures.
  • Aerospace – Ensures the structural integrity of aircraft components.
  • Manufacturing & Quality Control – Verifies material specifications in production processes.

Advantages of UTM Services

✔ Non-destructive and does not require cutting or damaging the material.
✔ Highly accurate and reliable measurements.
✔ Quick and cost-effective solution for corrosion monitoring.
✔ Can be used on both accessible and hard-to-reach areas.

Benefits of Ultrasonic Thickness Measurement (UTM) on Vessels

Ultrasonic Thickness Measurement (UTM) is a crucial inspection method for vessels, including ships, storage tanks, and pressure vessels. It helps ensure safety, regulatory compliance, and operational efficiency.

6 Benefits of Ultrasonic Thickness Measurement (UTM) on Vessels

1. Corrosion & Erosion Monitoring

  • Detects material loss due to corrosion, pitting, or erosion inside the vessel.
  • Helps predict maintenance schedules before structural integrity is compromised.

2. Safety & Structural Integrity

  • Prevents catastrophic failures by identifying weak spots in the vessel structure.
  • Ensures leak prevention, avoiding hazardous spills or explosions.

3. Compliance with Regulations

  • Meets industry standards such as ABS, DNV, Lloyd’s Register, ASME, API, and IMO requirements.
  • Essential for classification surveys and vessel certification.

4. Non-Destructive & Cost-Effective

  • No need to cut or damage the vessel structure.
  • Reduces downtime compared to destructive testing methods.
  • Minimizes repair costs by addressing issues early.

5. Works in Hard-to-Reach Areas

  • Can be used on curved surfaces, tight spaces, and underwater sections.
  • Portable equipment allows for on-site inspections without removing components.

6. Data Logging & Trend Analysis

  • Provides historical data tracking for long-term corrosion monitoring.
  • Helps in predictive maintenance and life cycle assessment of the vessel.
