The half-angle (between the taper surface and the axis of the pipe) is arctan(1 ⁄ 32) ≈ 1.7899° ≈ 1° 47′. The standard for Nominal Pipe Size (often abbreviated NPS, which should not be confused with the abbreviation NPS for the straight thread form standard) is loosely related to the inside diameter of Schedule 40 series of sizes.
Alternatively it is a short length of pipe with two female National pipe threads (NPT) (in North American terms, a coupler is a double female while a nipple is double male) or two male or female British standard pipe threads. If the two ends of a coupling are of different standards or joining methods, the coupling is called an adapter. Examples ...
The overstressed female fitting may split days, weeks, or even years after initial installation. Therefore many municipal plumbing codes restrict the use of threaded plastic pipe fittings. Both British standard and National pipe thread standards specify a thread taper of 1:16; the change in diameter is one sixteenth the distance travelled along ...
In plumbing and piping, a nipple is a fitting, consisting of a short piece of pipe, usually provided with a male pipe thread at each end, for connecting two other fittings. The length of the nipple is usually specified by the overall length with thread.
However, because the straight and tapered iron pipe threads differ only in their taper, it is possible for small NPSH/SIPT female hose couplings in sizes 1 ⁄ 2 inches to 4 inches (inclusive) to be joined to NPT male pipe ends. The connection uses a gasket to seal, and is temporary.
Type DC or Type IX: dust caps (female) Type DP or Type X: dust plugs (male) [2] Apart from these basic types, the hose/pipe connection side of a cam and groove coupler can be of various other types such as with a flange, for butt welding to a container, for truck use with a sight glass, etc. These couplings are available in the following diameters:
