NPT, or ANSI/ASME B1.20.1 Pipe Threads, is a standard for tapered threads with a specific angle and pitch. The threads have a 1o 47' taper angle, with flat roots and crests, and a 60o thread angle. The pitch is measured in threads per inch. The outside diameter of a...
requires that all basic design dimensions be met, (within applicable tolerances), including taper, thread truncations, lead, and flank angle over the L2and L3lengths.” The L2& L3part threads may be inspected using optical methods in conjunction with measurement and control of the cutting tools...
