Seamless steel pipe inspection specification

There are many things that seamless steel pipes(a53 seamless) need to be tested, especially after they leave the factory, they need to be continuously tested for all links and models of seamless steel pipes. What aspects should be tested for common seamless steel pipes?

1. Seamless steel pipe wall thickness inspection: micrometer, ultrasonic thickness gauge, no less than 8 points at both ends and record.

2. Check the outer diameter and ovality of seamless steel pipe: caliper, vernier caliper, ring gauge, and measure the maximum and minimum points.

3. Seamless steel pipe length inspection: steel  tape measure, manual and automatic length measurement.

4. Seamless steel pipe curvature inspection: straightedge, level (1m), feeler gauge, thin wire to measure the curvature per meter and the full length curvature.

5. Inspection of the bevel angle and dull edge of the seamless steel pipe end face: square, pallet.

Surface quality inspection of seamless steel pipe:

1. Artificial visual inspection: lighting conditions, standards, experience, signs, seamless steel pipe rotation.
2. Non-destructive flaw detection: ultrasonic flaw detection UT, eddy current flaw detection ET, magnetic particle MT and magnetic flux leakage flaw detection, electromagnetic ultrasonic flaw detection, penetrant flaw detection.
