At High Technology Nondestructive Testing Service Co., Ltd, we provide Automated Ultrasonic Testing (AUT)—the most advanced and productive inspection solution for pipeline construction and large-scale fabrication. By integrating high-speed robotics with phased array and ToFD technology, we deliver rapid, repeatable, and highly accurate inspection data that keeps your project moving.

Precision Engineering & Robotics

Our AUT systems utilize specialized mechanical crawlers and computerized control units to eliminate the variables of manual testing. This ensures that every millimeter of the weld is inspected with consistent pressure, angle, and sensitivity.

• Zonal Discrimination: Utilizing advanced focal laws to divide the weld into specific “zones,” allowing for high-speed detection of lack of fusion and other critical defects.

• Rapid Cycle Times: Designed specifically for the fast-paced environment of pipeline “lay-barges” and cross-country spreads, where inspection must be completed in minutes to match production speeds.

• 100% Data Integrity: Automated encoders track the exact position of the probes, ensuring that every scan is perfectly mapped to the physical weld for total traceability.

The AUT Advantage: Productivity & Safety

• Instant On-Site Analysis: Results are available immediately after the scan, allowing for “real-time” repair decisions and minimizing costly construction delays.

• The Safer Alternative to Radiography: AUT provides superior defect sizing and detection without the safety hazards, exclusion zones, or environmental concerns of Gamma or X-ray radiography.

• Engineering Critical Assessment (ECA): The high-precision sizing data provided by AUT allows for the use of ECA acceptance criteria, which can significantly reduce unnecessary repair rates compared to traditional “workmanship” standards.

Technical Compliance & Quality Assurance

Our AUT services are delivered by a team of elite technicians specialized in automated system calibration and data interpretation.

• Codes & Standards: Fully compliant with ASTM E1961, API 1104 (Annex A), and DNV-ST-F101.

• Advanced Reporting: We provide comprehensive digital “strip-charts” and color maps that offer a clear, permanent record of the weld quality for project owners and regulatory bodies.
