Wall Thickness Inspection: Utilize tools such as micrometers and thickness gauges to measure the wall thickness of steel tubes, ensuring it falls within the specified tolerance range.
Outer Diameter and Ovality Inspection: Employ tools like snap gauges, vernier calipers, and ring gauges to measure the outer diameter and ovality of steel tubes, assessing their geometric dimensional accuracy.
Length Inspection: Use steel tape measures to determine the length of steel tubes, confirming compliance with the requirements of fixed-length or multiple-length specifications.
Camber Inspection: Leverage tools like rulers, level gauges, and feeler gauges to measure the camber per meter and over the entire length of steel tubes, ensuring their straightness.
End Face Groove Angle and Blunt Edge Inspection: Inspect the groove angle and blunt edge dimensions of steel tube end faces using tools like angle squares and clamping plates to ensure they meet welding requirements.
