What do the various digits in this gasket model mean?

The gasket used on the lid of the chlorine acid mist catcher is model B22-1600-0.6. I would like to know what the numbers in this model mean. I assume that 1600 refers to the inner diameter of the gasket (since the inner diameter of the acid mist catcher is 1600). What do the other numbers represent? Please advise me; thank you
B22 refers to an inner ring gasket made of 304 material with flexible graphite; 1600 is the nominal pressure drop, and 0.6 is the nominal pressure
B22 should be the inner ring gasket; the material of the inner ring is 304, while the non-metallic material is graphite ； 1600 is the nominal diameter, and 0.6 might be the nominal pressure; I’m not sure, please advise!
If it’s a metal wound gasket, there are four types: A, B, C, and D. However, there should be four digits after the letters, which indicate the material of the inner ring, the metal material, the filler material, and the material of the outer ring. But here there are only two digits, so it’s not clear. I would appreciate advice from those who are more knowledgeable. 1# Yi Nuo Zhang
According to national standards, B--enhanced ring type outside the band; 22--metallic band material: 0Cr13; non-metallic band material: flexible graphite; 1600---nominal diameter of 1600 mm; 0.6--nominal pressure of 0.6 Mpa； Since there are many standards, it is first necessary to determine whether they are national standards or other non-national standards.
