The measurement of circular pipes requires the use of some tools, including vernier calipers, tape measures, micrometers, roundness measuring instruments, and other tools.
Vernier caliper: used to measure diameter or length. The size of the circular tube can be accurately read through the scale on the caliper.
Micrometer: used to measure wall thickness. The size of the circular tube can be accurately read through the scale of the micrometer or the screen display.
Tape measure: commonly used for measuring length. Choosing a tape measure with a locking device can facilitate single person operation.
Roundness measuring instrument: It can measure the roundness of a circular tube with a certain degree of accuracy and is suitable for situations that require high precision.
