Notes
- The threaded pipe flanges 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 locknut threads)
- Class 1500 and higher threaded flanges are counter-bored. Threads
are chamfered to the counterbore at an angle of 450
(approx)
- Pipe flanges weights are based on manufacturer's data and are
approximate
