Threaded Flanges :
ANSI B16.5 Class150 lb Threaded Flanges :
The thread conforms to ASME B1.20.1 NTP threads as described in Section 10. (The only exceptions are small male and female plain face threaded flanges which use NPSL recount threads);
Class 150 threaded flanges are made without a counterbore. Threads are chamfered to the major diameter (approx.) at an angle of 45 ° (approx.) at the back of the flange;
Weights are based on manufacturer’s data and are approximate.
