1. Steel pipe geometry and shape inspection:
① Steel pipe wall thickness inspection: micrometer, ultrasonic thickness gauge, no less than 8 points at both ends and record.⑤ Steel pipe end bevel angle and blunt edge inspection: angle ruler, clamping plate.
No coupling medium is required, and it can be applied to high-temperature, high-speed, and rough surface flaw detection of steel pipes.
e. Penetration testing:
Fluorescence, coloring, and detection of steel pipe surface defects.
