The Synergy Advantage: Why ET+UT Combined Systems Deliver Superior Results

In the demanding world of steel pipe manufacturing and quality assurance, the stakes couldn't be higher. A single undetected flaw in critical applications like oil and gas pipelines, nuclear facilities, or aerospace components can lead to catastrophic failures, costly downtime, and safety hazards. That's why industry leaders trust our advanced Eddy Current Testing (ECT) and Ultrasonic Testing (UT) combined systems to deliver uncompromising quality control.

Steel pipes face numerous potential defects throughout their lifecycle - from manufacturing processes like forging and welding to service-related issues such as corrosion and fatigue. Understanding these defect types is crucial for implementing effective detection strategies.

Eddy Current Testing represents the pinnacle of non-contact surface inspection technology. By utilizing electromagnetic induction principles, our ECT systems generate eddy currents within conductive materials and monitor their variations to identify defects with exceptional precision.

Key Defect Types Detected by ECT:

Crack Detection:

• Longitudinal Cracks: Defects extending along the pipe's axial direction
• Transverse Cracks: Defects perpendicular to the pipe's axis
• Surface Cracks: Visible surface discontinuities
• Sub-surface Cracks: Near-surface defects just below the material surface

Corrosion Assessment:

• Pitting: Localized micro-cavity corrosion
• General Corrosion: Widespread surface material thinning
• Wall Thinning: Reduced wall thickness due to corrosion or wear

Manufacturing Defects:

• Lack of Fusion: Incomplete fusion between weld metal and base material
• Porosity: Gas-induced micro-cavities in welds
• Laps: Surface overlaps from rolling or forging processes
• Laminations: Internal layered defects from manufacturing impurities

The beauty of ECT lies in its speed and sensitivity to surface defects, making it ideal for high-speed production line integration.

While ECT dominates surface inspection, Ultrasonic Testing penetrates deep into material structures, revealing internal defects that could compromise structural integrity. Our UT systems utilize high-frequency sound waves to detect, locate, and size internal discontinuities with remarkable accuracy.

Comprehensive Internal Defect Detection:

Weld Quality Assessment:

• Weld Cracks: Including longitudinal, transverse, and crater cracks
• Lack of Fusion: Incomplete bonding between weld passes or base material
• Lack of Penetration: Insufficient weld root penetration
• Slag Inclusions: Non-metallic impurities trapped in welds
• Porosity: Internal gas pockets within weld metal

Base Material Integrity:

• Laminations: Parallel-to-surface layered defects from rolling processes
• Inclusions: Internal non-metallic impurities
• Shrinkage Cavities: Voids from casting or forging cooling processes
• Wall Thickness Monitoring: Precise measurement for corrosion assessment

Advanced Surface Detection:
Through specialized probes and surface wave techniques, UT can also detect:

• Surface cracks with precise depth measurement
• Corrosion mapping and profiling

In our 31 years of NDT automation experience, we've learned that no single technology can address every defect scenario. That's why our integrated ET+UT systems represent the gold standard in comprehensive pipe inspection.
