Standards of flanges vary worldwide, meaning that in most cases they are not interchangeable. The size, drilling and pressure range will be different (ie a PN16 flange is not rated to the same pressure class as a PN40 flange. ..nor would a PN16 flange fit an ANSI 150 flange)
To make the selection process easy we use flange tables which show the most common standards used worldwide. These include: ANSI / ASME (USA), PN / DIN (European), BS10, Table E, Table D, Table F (British), and JIS/KS (Japanese/Korean).
