Threaded Flanges - ANSI B16.5
Notes- 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.- For tolerances see page 8-4.
