The unit is mm. [for example, seamless steel tubes of phi 32 * 3. It means that the nominal diameter (outside diameter) is seamless steel pipe of phi 32mm and wall thickness 3mm.

Q: How do you measure the thickness of steel pipes?: There are several methods available for measuring the thickness of steel pipes, depending on the desired level of accuracy. One commonly utilized technique is ultrasonic measurement. This involves employing an ultrasonic thickness gauge, which emits high-frequency sound waves that travel through the walls of the pipe and reflect back to the gauge. By calculating the time it takes for the sound waves to travel and return, an accurate measurement of the thickness can be obtained. This method is non-destructive and can be applied to both ferrous and non-ferrous materials. Alternatively, calipers or micrometers can be used for measurement. This entails manually measuring the outer diameter (OD) and inner diameter (ID) of the pipe, and then subtracting the ID from the OD to determine the thickness. However, it should be noted that this method is less precise compared to ultrasonic measurement. In cases where extreme precision is not necessary, a simple tape measure or ruler can be employed to measure the outer diameter of the pipe. The thickness can then be estimated by referring to standard pipe thickness charts or tables. It is essential to emphasize the significance of accurately measuring the thickness of steel pipes in various applications, such as construction, manufacturing, and engineering. Consequently, it is advisable to utilize suitable measuring tools and techniques to ensure precise results.
