Product Introduction

Overview

Our High Precision Seamless Pipe Ultrasonic Testing Machine is a fully automatic CNC-powered NDT system designed for 100% volumetric inspection of seamless and ERW oil pipes, casings and production tubing.

Fitted with high-performance ultrasonic transducer arrays, it delivers high-sensitivity detection of longitudinal cracks, transverse fissures, oblique defects and laminar delaminations. It can complete accurate full-length wall thickness measurement alongside flaw detection in one inspection cycle.

All inspection processes and data logging fully comply with authoritative API 5CT and API 5L standards, effectively satisfying strict quality control standards for OCTG manufacturers across the global oil and gas sector.

Working Principle

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.
