Seamless steel pipe model pressure comparison table
Thread Content
Help: A table comparing seamless steel pipe sizes (outer diameter X wall thickness) with pressure ratings?
20 on the first line is GB8163
It can’t be simply compared in this way; different media and materials have varying corrosion margins.
It’s used quite often. Since the original poster didn’t provide parameters such as medium, temperature, and pressure, I’ve uploaded a regular table; you’ll need to calculate the corrosion medium yourself. Thank you

This should be based on standards. Refer to HG/T20553-2011
The formula is used for calculation; thereafter, the wall thickness is determined by querying the pipe code. The pipe code SCH is calculated as: DESIGN PRESSURE (MPa) / ALLOWABLE STRESS OF THE MATERIAL AT THE DESIGN TEMPERATURE * 1000
