As the title suggests, does anyone know what these abbreviations mean? FLANGE WITH J.B WN 23.83MM RF 300# ASME B16.47-B, 32\": I’m not sure what J.B refers to here; why is there a dimension of 23.83MM? LINE BLANK BLK&SPC RF 150# ASME B16.47-B, 30\": If BLK means BLANK, then does SPC mean SPACE? SADDLE FLANGE (PAD FLANGE) RF 300#, 4\": Is this the so-called saddle flange? Does anyone have any relevant ASME/ANSI standards that I can refer to? Thank you very much.

So far, this flanged fitting design can only be found in the Ministry of Chemical Industry standard HG/T-21564.
