Steel pipe geometry and shape inspection:
` Inspection of steel pipe wall thickness: micrometer, ultrasonic thickness gauge, no less than 8 points at both ends and record.
aExamination of steel pipe outer diameter and ovality: caliper, vernier caliper, ring gauge, measure the maximum and minimum points.
b Steel pipe length inspection: steel tape measure, manual and automatic length measurement.
c Inspection of steel pipe curvature: straightedge, level (1m), feeler gauge, thin wire to measure curvature per meter and full length curvature.
d Inspection of bevel angle and blunt edge of steel pipe end face:
