Can a flange with a pressure rating of 1.6 MPa and a nominal diameter of 200 mm be denoted as PN16 DN200? Still PN1.6 DN200?

Now the flange standards are all HG/T 20592-2009, so PN16 DN200 is correct

In the standards, the pressure unit is Bar

It is recommended that the original poster check the standard GB 1048; following the standard specifications is what matters
