2. National pipe thread - Wikipedia

   en.wikipedia.org/wiki/National_pipe_thread

   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.

3. British Standard Pipe - Wikipedia

   en.wikipedia.org/wiki/British_Standard_Pipe

   In the modern standard metric version, it is simply a size number, where listed diameter size is the major outer diameter of the external thread. For a taper thread, it is the diameter at the "gauge length" (plus/minus one thread pitch) from the small end of the thread.

4. Nominal Pipe Size - Wikipedia

   en.wikipedia.org/wiki/Nominal_Pipe_Size

   Nominal Pipe Size (NPS) is a North American set of standard sizes for pipes used for high or low pressures and temperatures. [1] " Nominal" refers to pipe in non-specific terms and identifies the diameter of the hole with a non-dimensional number (for example – 2-inch nominal steel pipe" consists of many varieties of steel pipe with the only criterion being a 2.375-inch (60.3 mm) outside ...

   The major diameter still extends to within ⁠ 1 / 8 ⁠ H of the theoretical sharp V, but the total depth of the thread is reduced 4% from ⁠ 5 / 8 ⁠ H = ⁠ 5 / 8 ⁠ cos(30°) P ≈ 0.541P to 0.52P. [5] This increases the amount of the theoretical sharp V which is cut off at the minor diameter by 10% from 0.25H to ⁠ 7 / 8 ⁠ − ⁠ 0. ...
