Pipe thread sizes are described much as bolt sizes are,although the shapes are different. For example,½14 NPT identifies a pipe thread with a nominal inside diameter of ½ inchand 14 threads to the inch,made according to the NPT standard.American pipe threads - Sizes What does NPT thread stand for?What does NPT thread stand for?NPTstandsfor National Pipe Taper,and is the most common U.S. standard for pipe fittings. NPTfittings are measured on the internal diameter of the fitting. AN fittings were designed originally for the U.S. Military (The "A" standingfor Army,and the "N" standingfor Navy).What does NPT, BSP etc mean? - Mini Mania, Inc.

What is the size of a standard pipe thread?What is the size of a standard pipe thread?National Pipe Threadis a U.S. standard for tapered (NPT) or straight (NPS) threads used to join pipes and fittings.

Both NPT and ANPT taper pipe threads have the same general form andAmerican National Pipe - PipeandHoseBoth NPT and NPS have the same thread angle, shape, and pitch (threads per inch). However, NPT threads are tapered and NPS threads are straight (parallel). Both threads have a 60° included angle and have flat peaks and valleys (this is a Sellers thread form). If you've worked with pipe much at all, you've probably noticed that the size of the pipe isn't really what size the pipe is.

NPT has flattened peaks and troughs where BSP is rounded. NPT has a thread angle of 60º where BSP is 55º. At certain sizes, NPT and BSP share the same number of threads per inch - at ½" and ¾" - but at all other sizes the two are quite different. The table below lists the TPI for both NPT and BSP at sizes commonly used with domestic radiators.National Pipe Taper Railing - NPTR PipeandHoseNational Pipe Taper Railing - NPTR. This thread is used on stair banister railings and similar mechanical applications. Care must be taken not to confuse this thread with one intended to perform a hydraulic sealing function.

Sizes smaller than 1/8 inch are occasionally used for compressed air, while sizes larger than 2 inches are uncommon, due to the use of alternative methods of joining that are used with these larger sizes.
