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 locknut threads)
Class 300 and higher threaded flanges are counter-bored. Threads are
chamfered to the counterbore at an angle of 450 (approx)
Weights are based on manufacturer's data and are approximate
