Pipe thread pitch
NPT is defined by ANSI/ASME standard B1.20.1. The taper rate for all NPT threads is 1 inch of diameter in 16 inches of length (3⁄4 inch per foot or 62.5 millimeters per meter) measured by the change of diameter (of the pipe thread) over distance of thread. The half-angle (between the taper surface and the axis of the pipe) is arctan(1⁄32) ≈ 1.7899° ≈ 1° 47′.

WebbPipe Threads ___. BASIC DIMENSIONS OF AMERICAN NATIONAL STANDARD TAPER THREADS, NPT (ASME B1.20.1) E = Pitch diameter at hand-tight plane. This is also the pitch diameter at the gauge plane. L 2 = Effective length of thread = Truncation from point of thread triangle to flat (not shown in diagram). WebbThe pitch is the distance from the crest of one thread to the next in milimeters (mm). TPI (threads per inch) is used by inch thread. Diameter The major diameter is determined by the thread tips. The minor diameter is determined by the groove of the thread.
WebbMaximum thread height according to standard is 6/8 H. H = 0.866 × P (H = Basic triangle height) (P = thread pitch) Maximum thread height is: 6/8 * (0.866 × 1.25) = 0.811 mm Actual thread height at a core hole of Ø 6.9 mm: (8–6.9) / 2 = 0.55 mm Thread height is then (0.55 / 0.81) × 100 = 68% Are you looking for tool recommendations?
