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.
