How can I find the outer diameter corresponding to the nominal diameter of a pipe?

What are the common sizes for 1/2" to 20"? Thank you
For American standard series: ASME B36.10, B36.19; see the following link: http://bbs.hcbbs.com/viewthread.php?tid=49362&highlight=36.10
Nominal diameter, also known as mean outside diameter. This is because the wall thickness of metal tubes is very thin, and the outer diameter and inner diameter are almost identical; therefore, the average of the outer and inner diameters is used as the diameter of the tube. The nominal diameter of seamless steel pipes refers to the outer diameter of the pipe; it is not equal to the outer diameter itself, but it is close to the inner diameter value. The nominal diameter of welded steel pipes refers to their outer diameter. The nominal diameter of containers, cylinders, and end caps refers to their inner diameter. The nominal diameter of a cylindrical vessel made of seamless tubing refers to the outer diameter of the steel tube. The nominal diameter of a flange refers to the nominal diameter of the cylinder, head, or pipe that it is fitted with. The nominal diameter of bolts and nuts refers to the major diameter of the thread, that is, the diameter of the crest of the external thread (bolt) or the root of the internal thread (nut).
It is recommended that the original poster visit this website on Haichuan Forum, where forum members have already provided the inner and outer diameters corresponding to the nominal diameter. http://bbs.hcbbs.com/thread-305462-1-1.html
