Notes:-
The ANSI B 300 Class threaded flanges conforms to ASME B1. 20.1 NTP threads. (The only exceptions are small male and female plain face threaded flanges which use NPSL locknut threads). Class 300 and higher threaded flanges are counter-bored. Threads are chamfered to the counterbore at an angle of 450 (approx) ANSI B 300 Class flanges weights are based on manufacturer's data and are approximate
