Ultrasonic Testing (UT) & Advanced Ultrasonic Examination

At High Technology Nondestructive Testing Service Co., Ltd, our Ultrasonic Testing (UT) services provide a high-precision “window” into the internal structure of your materials. Using high-frequency sound waves, we detect subsurface flaws, measure thickness, and evaluate material integrity with surgical accuracy—all without compromising the component’s functionality.

Our Ultrasonic Inspection Capabilities

1. Conventional Ultrasonic Testing (Manual UT)

Ideal for rapid onsite inspections of welds, castings, and forgings.

• Flaw Detection: Identifying volumetric defects such as porosity, inclusions, and cracks.

• Lamination Checks: Verifying the internal soundness of base plates before fabrication.

• Thickness Gauging: Accurate measurement of wall thinning caused by corrosion or erosion in piping and storage tanks.

2. Advanced Ultrasonic Solutions

For complex geometries or critical assets, we deploy state-of-the-art digital imaging technologies:

• Phased Array Ultrasonic Testing (PAUT): Utilizing multi-element probes to create “color-coded” cross-sectional views, offering superior probability of detection (PoD).

• Time of Flight Diffraction (ToFD): A highly sensitive method for precise crack sizing and monitoring of defect growth over time.

Technical Compliance & Quality

Our UT procedures are strictly governed by international codes, ensuring that every decibel of data is reliable:

• Standards: Compliance with ASME Section V, ASTM E164, ISO 17640, and AWS D1.1.

• Certified Expertise: All inspections are performed by ISO 9712 / ASNT Level II or III certified technicians.

• Digital Traceability: We provide comprehensive inspection reports, including A-scan, B-scan, or C-scan data, ensuring transparent documentation for your quality records.

Why Choose HTNDT for Ultrasonic Testing?

• Instant Results: Our portable, high-tech equipment allows for immediate on-site evaluation, helping you make informed “Go/No-Go” decisions quickly.

• Deep Penetration: Capable of inspecting thick-walled components that are difficult to evaluate via Radiography.

• Safety & Environment: Unlike X-rays, UT requires no radiation safety zones, allowing your other site activities to continue without interruption.
