This NPT Thread Size Chart provides specifications for various nominal pipe sizes, including outside diameter, threads per inch (TPI), pitch, taper rate, thread length, effective thread length, and hand-tight engagement length. Among the different types of threads, the National Pipe Thread (NPT) stands out due to its widespread use and I'll be the first to admit that I have always been somewhat confused by best-practice dimensioning standards surrounding pipe threads. Step 5: Make the height of the undercut half an inch. Taper: Tapered threads, like NPT and BSPT, have a gradual change in diameter over the length of the thread.

ISO threads have 55 o taper angle versus 60 o for NPT. 2-11. e. 1 provides a 1° 47' taper consistent with inch on the thread, facilitating leak-unfastened connections in piping systems. 5763 degrees, but we want the angle on the radius so that you can divide the angle by 2. Projected tolerance might be appropriate for a fitting*, which presumably projects some distance above the plate, but it doesn't solve the issue of applying position/perpendicularity to a conical feature - unless you think standard position I have an issue drawing up an NPT thread in Mastercam. The tap has a tapper on it, s if I don't tell where to the machinist to stop in depth with the tap, the hole will be over sized, so the NTP fitting will not thread in tight.
