Steel pipe geometry and shape inspection,Square, card board. Steel pipe surface quality inspection,Steel management performance inspection

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:

Square, card board. Steel pipe surface quality inspection: 100%

` Manual visual inspection: lighting conditions, standards, experience, signs, steel pipe rotation.

aNon-destructive inspection:

Standard: GB/T 5777-1996 Level: C5

Stalaoji.orgndard: GB/T 7735-2004 Level: Level B

Steel management performance inspection:

Tips:

ASTM A500 is a carbon steel cold-formed round section and special-shaped section welded square pipe and seamless square pipe for structural use.
