What is the difference between American standard octagonal gaskets PN10.0 and PN11.0? Aren’t they all 600 pounds?

They are two different pressure series. PN11.0 belongs to the American standard series, with values such as 2.0 and 5.0; PN10.0 belongs to the European standard series, with values such as 1.6； 2.5 ； 4.0 grade

The answer is upstairs~~~~~~~ The two belong to different pressure rating systems~~

The execution standards are all HG/T20633; they are indeed American-standard gaskets. The sizes and models are the same, but the specified pressure ratings differ

PN10.0 corresponds to the European standard HG/T20612-2009, while PN11.0 corresponds to the American standard HG/T20633-2009

One is European standard and the other is American standard; the sizes differ slightly.
