Phased Array Ultrasonic Testing (PAUT) Services

At High Technology Nondestructive Testing Service Co., Ltd, we bring the future of inspection to your job site. Phased Array Ultrasonic Testing (PAUT) is our premier advanced NDT solution, offering an unmatched level of detail through high-resolution, cross-sectional imaging of internal structures.

The Power of Multi-Element Technology

Unlike conventional UT, which uses a single fixed beam, our PAUT systems utilize multi-element probes and computer-controlled “focal laws.” This allows us to steer, focus, and scan beams at thousands of different angles simultaneously.

• Complete Volumetric Coverage: Detects defects regardless of their orientation within the weld or base material.

• Permanent Digital Record: Every scan is recorded as a high-definition color map (S-Scan and C-Scan), providing “visual proof” of integrity for auditors and clients.

• High Probability of Detection (PoD): Superior sensitivity to small cracks, lack of fusion, and porosity that traditional methods might miss.

Key Advantages for Your Project

• Speed & Efficiency: A single scan from one position can cover the entire weld volume, significantly reducing inspection time compared to manual UT.

• Radiation-Free Safety: PAUT is the ideal alternative to Radiography (RT). It requires no safety clearances or site evacuations, allowing other trades to continue working nearby without interruption.

• Complex Geometry Inspection: Highly effective for heavy-wall pressure vessels, turbine blades, and complex nozzle-to-shell welds.

Technical Compliance & Expertise

Our PAUT services are executed by specialized Level II and Level III technicians trained in advanced data interpretation.

• Codes & Standards: Fully compliant with ASME Section V (Article 4), ISO 13588, and ASTM E2700.

• Advanced Reporting: We provide comprehensive digital reports featuring encoded data, ensuring 100% traceability and repeatability for future maintenance cycles.
