BSPT Pipe Threads. 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. They always use a taper male thread, but can have either parallel or taper female threads. (International standards require all female threads to be parallel.) Longscrew threads These are parallel pipe threads used where a pressure-tight joint is achieved by the compression of a soft material (such as an o-ring seal or a washer) between the end face of the male thread and a socket or nipple face, with the tightening of a backnut. Thread form [ ] The thread form follows the standard: • Symmetrical V-thread in which the angle between the flanks is 55° (measured in an axial plane) • One-sixth of this sharp V is truncated at the top and the bottom • The threads are rounded equally at crests and roots by circular arcs ending tangentially with the flanks where r=0.1373P • The theoretical depth of the thread is therefore 0.6403 times the nominal pitch Pipe thread sizes [ ] At least 41 thread sizes have been defined, ranging from 1⁄ 16 to 18, although of these only 15 are included in ISO 7 and 24 in ISO 228. The size number was originally based on the inner diameter (measured in inches) of a steel tube for which the thread was intended, but contemporary pipes tend to use thinner walls to save material, and thus have an inner diameter larger than this nominal size. 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.

Brigandine Grand Edition Eng Eboot. For a taper thread, it is the diameter at the 'gauge length' (plus/minus one thread pitch) from the small end of the thread. The taper is 1 to 16, meaning that for each 16 units of measurement increase in the distance from the end, the diameter increases by 1 unit of measurement. Jquery 3d Carousel Slider on this page.
