100% Weld Seam Non-Destructive Testing
The weld zone of every nickel alloy welded pipe and tube undergoes rigorous NDT inspection:
- Radiographic Testing (RT): Detecting internal weld defects, conforming to ASTM E94/E142 standards
- Ultrasonic Testing (UT): Detecting defects in weld and HAZ, conforming to ASTM E213 standard
- Penetrant Testing (PT): Detecting surface-opening defects in the weld, conforming to ASTM E165 standard
- Eddy Current Testing (ET): Suitable for full-body inspection of small diameter welded tubes
