  Inspection of geometric dimensions and shape of seamless steel pipes 1. Steel pipe wall thickness inspection: micrometer, ultrasonic thickness gauge, no less than 8 points on both ends and record. 2. Inspection of the outer diameter and ellipticity of the steel pipe: caliper gauge, vernier caliper ring gauge, and the maximum and minimum points are measured. 3. Steel tube length check: steel tape measure, manual and automatic length measurement. 4. Checking the bend of steel pipe: ruler, horizontal ruler (1m), ruler and thin line measure the bend of every meter and bend of every meter. 5. Check the angle and blunt edge of the end face of the steel pipe: square ruler, card board. Steel pipe surface quality inspection: 1. Artificial visual inspection: lighting conditions, standards, experience, logo, 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, elec...
