Regarding metal wound gaskets for flanges
Thread Content
Metal wound gaskets for flanges are specified according to the HG20615-2009 standard. Could a situation like 0220 occur, where there is neither a central ring nor an inner ring?

0222: The first digit denotes the “outer ring”, the second digit indicates the “steel frame material”, the third digit represents the “non-metallic filler ring material”, and the fourth digit refers to the “inner ring””； Metal wound gaskets: Basic wound gasket (0220), wound gasket with inner ring (0222), wound gasket with outer ring (2220), wound gasket with inner and outer rings (2222)
