Taper angle of npt

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′. WebTaper Conical NPT Hole Prep End Mill Carbide end mills designed to prepare an existing hole for an NPT / NPTF tap or thread mill operation. Allows the user to mill an existing hole with a conical form in line with the minor diameter of a pipe thread created via thread milling.
