I would like to ask the teachers: Where can I find the wall thickness of pipes with the same nominal diameter but different pipe schedule numbers? It is best to include the outer diameter of Series A and the outer diameter of Series B

The last edit to this post was made by Asuka Sky on 2022-3-9 at 17:25. In HT/T 20553, steel pipe sizes are divided into three series: Ia, Ib, and II. The first two series have wall thicknesses corresponding to different pipe nominal sizes; why isn’t there a pipe nominal size for series II?

There is an explanation in 2.0.4 about where the charts are located

For example, for seamless steel pipes with dimensions of φ630*24, it is not possible to determine what the corresponding pipe schedule number SCH is
