New version of HG/T20592-2009 flange pressure

Thread Content

Is the maximum pressure for flanges under the new version of HG/T20592-2009 16 MPa? If a pressure of 25 MPa is required, should one use the American standard Class1500 PN260? Seeking advice from experts!

That’s right, that’s how it’s designed; it is a bit troublesome! Hehe

The new standard specifies a maximum of 16 MPa, but this isn’t a problem; generally, industries don’t use such high pressures. Even in cases where 25 MPa is required, it’s more appropriate to use American standards
