UCI Hardness Testing Services in UAE | Portable Non-Destructive Hardness Testing by AIMMS Group

Accurate On-Site Hardness Testing for Industrial, Marine & Offshore Assets

At AIMMS Group, we provide professional Ultrasonic Contact Impedance (UCI) Hardness Testing & Leeb Hardness Testing services across the UAE for the marine, offshore, oil & gas, petrochemical, fabrication, and industrial sectors.

Material hardness is a critical property that helps determine the strength, durability, and performance of metallic components. Our UCI hardness testing services provide a practical and efficient method for assessing the hardness of components, welds, and heat-affected zones directly at the inspection site.

As part of our comprehensive Non-Destructive Testing (NDT) Services, UCI Hardness Testing enables accurate hardness measurements without the need to remove components from service. This helps reduce inspection-related downtime while supporting material verification, quality control, and asset integrity.

What is UCI Hardness Testing?

Ultrasonic Contact Impedance (UCI) Hardness Testing is a portable inspection method used to determine the hardness of metallic materials. The equipment uses a Vickers diamond indenter attached to a vibrating rod. When a controlled force is applied to the test surface, the instrument measures the ultrasonic frequency shift and instantly calculates the hardness value.

This method is widely used for quality control, fabrication, maintenance, and in-service inspections where conventional hardness testing is not practical.

The inspection area is cleaned to ensure accurate hardness measurements.

2. Equipment Verification

The UCI hardness tester is verified using certified reference blocks before inspection.

3. Hardness Measurement

Multiple hardness readings are taken at specified locations using the appropriate test force.

4. Result Evaluation

Measured values are compared with the applicable project specifications, codes, and acceptance criteria.

5. Professional Reporting

Clients receive a detailed inspection report including:

·       Test locations

·       Hardness readings

·       Equipment details

·       Inspection procedure

·       Acceptance criteria

·       Inspection results

·       Remarks
