  2. National pipe thread - Wikipedia

    en.wikipedia.org/wiki/National_pipe_thread

    Because of the pipe wall thickness of Schedule pipe, the actual diameter of the NPT threads is larger than the Nominal Pipe Size diameter, and considerably so for small sizes. Pipe of a given size in a different Schedule than Schedule 40 provides a different wall thickness while maintaining the same outside diameter and thread profile as ...

  3. British Standard Pipe - Wikipedia

    Taper threads, British Standard Pipe Taper thread (BSPT), whose diameter increases or decreases along the length of the thread; denoted by the letter R. BSPT threads [2] These can be combined into two types of joints: Jointing threads These are pipe threads where pressure-tightness is made through the mating of two threads together.

  5. British Standard Whitworth - Wikipedia

    en.wikipedia.org/wiki/British_Standard_Whitworth

    These threads are designated by a number between 1/16 and 6 that originates from the nominal internal diameter (i/d) in inches of a steel pipe for which these threads were designed. These pipe thread designations do not refer to any thread diameter. Other threads that used the Whitworth 55° angle include Brass Threads, British Standard Conduit ...

  6. 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 ...

    en.wikipedia.org/wiki/AN_thread

    The AN thread (also A-N) is a particular type of fitting used to connect flexible hoses and rigid metal tubing that carry fluid. It is a US military-derived specification that dates back to World War II and stems from a joint standard agreed upon by the Army Air Corps and Navy, hence AN.

  9. Unified Thread Standard - Wikipedia

    en.wikipedia.org/wiki/Unified_Thread_Standard

    The standard designation for a UTS thread is a number indicating the nominal (major) diameter of the thread, followed by the pitch measured in threads per inch.For diameters smaller than ⁠ 1 / 4 ⁠ inch, the diameter is indicated by an integer number defined in the standard; for all other diameters, the inch figure is given.
