Method for measuring the length of rectangular tubes1. Use a steel ruler or tape measure to measure along the length of the pipeline.
2. Use measuring instruments for measurement, such as measuring instruments, laser rangefinders, etc.
Attention: When measuring the length, it is necessary to ensure that the measuring tool is placed flat and perpendicular to the length direction of the pipeline.
Method for measuring the width of rectangular tubes
1. Use a steel ruler or tape measure to measure along the width direction of the pipeline, or use a measuring instrument for measurement.
If the width of the rectangular tube is irregular, multiple measurements are required.
Attention: When measuring the width, it is necessary to ensure that the measuring tool is placed flat and perpendicular to the width direction of the pipeline.
Measurement method for thickness of rectangular tube
1. Use an outer diameter caliper or inner diameter caliper to measure along the four corners of the rectangular tube. If the rectangular tube is long, multiple measurements are required and the average value is taken.
2. Use ultrasonic measuring instruments for measurement.
Attention: When measuring thickness, it is necessary to ensure that the measuring tool is horizontal or perpendicular to the direction of the pipeline.
