I wonder if they use the size of the flange for piping, which in layman’s terms is the nominal diameter of the steel pipe. For example, if the flange size for piping is 57, does that mean the nominal diameter of a steel pipe with a diameter of 57 is DN50? We don’t call it that either; it’s my own idea. I’m not sure if it’s correct
