How are the pressure grades for pressure pipelines classified? That is, how to classify high-pressure pipes, medium-pressure pipes, and low-pressure pipes? Which document specifies this? Thank you!
It is generally classified into GC123 categories according to GBT 20801. What is the purpose of high, medium, and low-pressure pipelines?
GC A-B-C 1-2-3
The general ranges are 1.6 MPa and 10 MPa: values below 1.6 MPa are considered low pressure, those between 1.6 MPa and 10 MPa are medium pressure, and values above 10 MPa are high pressure
Refer to GB/T 20801
