نظرة عامة
Our OCTG آلة الكشف عن العيوب بالموجات فوق الصوتية is a fully automated, CNC digital control non-destructive testing system engineered to perform complete 100% volumetric inspection on both seamless and electric resistance welded oil pipes, oil casings and production tubing.
Equipped with high-performance ultrasonic transducer groups, it provides high-sensitivity detection of various pipe defects including longitudinal cracks, transverse fissures, oblique defects and laminar separations, while supporting synchronous full-length wall thickness measurement with outstanding precision.
All inspection procedures and data recording fully conform to authoritative industry standards including API 5CT and API 5L, meeting the strict quality testing requirements of global oil & gas OCTG manufacturing plants.
مبدأ العمل
The machine operates on the ultrasonic pulse-echo technique. High-frequency ultrasonic waves (2–5 MHz) are generated by piezoelectric probes and transmitted into the pipe wall via water-coupling.
- No defect: Ultrasound travels through the wall and reflects from the inner surface, producing a back-wall echo.
- With defect: Waves reflect earlier at discontinuities (cracks, inclusions, laminations), generating a defect echo before the back-wall signal.
- The system calculates defect depth, size, and position based on echo time and amplitude, enabling accurate, repeatable, and high-speed inspection.
