Regarding the classification of pipeline pressure grades
Thread Content
Dear Haihao friends! I’m looking for the criteria and data used to classify pressure pipelines into categories such as normal pressure, low pressure, medium pressure, high pressure, and ultra-high pressure, as well as the corresponding pressure grades for steam pipelines. Could anyone share this information? Thank you!
Without such standards, everyone defines them on their own
How is it possible to define it oneself? It’s not convincing.
I remember having seen a classification before: below 1.6 MPa is low pressure, 1.6–4.0 MPa is medium pressure, 4–10 MPa is high pressure, and above 10 MPa is ultra-high pressure
Yes, I’ve seen such a regulation as well. Are there any more detailed classifications, such as those specific to steam pipes?
