What are the differences between Series A and Series B flange gaskets? It would be best if everyone wrote down the specifications. For example, for DN150 flanges: metal wound gaskets for the inner and outer rings – Series A, PN2.0, T=4.5, D2222, SH3407-96; how should Series B be indicated?

The representation method is the same. Series A and Series B are designed for the outer diameter of pipes.

Agree with what was said above. Series A is the internationally standard series (imperial pipes) ； Series B is the commonly used series in China (metric pipes).
