Old English pipian "to play on a pipe," from Latin pipare "to peep, chirp" (see pipe (n.1)). Compare Dutch pijpen, German pfeifen. Meaning "convey through pipes" is first recorded 1887. Related: Piped; piping. Piping hot is in Chaucer, a reference to hissing of food in a frying pan; to pipe up (early 15c.) originally meant "to begin to play" (on a musical instrument); sense of "to speak out" is from 1856. Pipe down "be quiet" is from 1900, probably a reversal of this, but earlier (and concurrently) in nautical jargon it was a bo'sun's whistle signal to dismiss the men from duty (1833).

Old English pipe "musical wind instrument," also "tube to convey water," from Vulgar Latin *pipa "a pipe, tube-shaped musical instrument" (source also of Italian pipa, French pipe, Old Frisian pipe, German Pfeife, Danish pibe, Swedish pipa, Dutch pijp), a back-formation from Latin pipare "to chirp or peep," of imitative origin. All tubular senses ultimately derive from "small reed, whistle." Meaning "device for smoking" first recorded 1590s. Pipe-bomb attested from 1960. Pipe-cleaner recorded from 1863.

type of cask, early 14c., from Old French pipe "liquid measure, cask for wine," from a special use of Vulgar Latin *pipa "pipe" (see pipe (n.1)).

A pipe is a tubular wind instrument in general, or various specific wind instruments. The word is an onomatopoeia, and comes from the tone which can resemble that of a bird chirping.

A pipe is a tubular section or hollow cylinder, usually but not necessarily of circular cross-section, used mainly to convey substances which can flow — liquids and gases (fluids), slurries, powders and masses of small solids. It can also be used for structural applications; hollow pipe is far stiffer per unit weight than solid members.

In common usage the words pipe and tube are usually interchangeable, but in industry and engineering, the terms are uniquely defined. Depending on the applicable standard to which it is manufactured, pipe is generally specified by a nominal diameter with a constant outside diameter (OD) and a schedule that defines the thickness. Tube is most often specified by the OD and wall thickness, but may be specified by any two of OD, inside diameter (ID), and wall thickness. Pipe is generally manufactured to one of several international and national industrial standards. While similar standards exist for specific industry application tubing, tube is often made to custom sizes and a broader range of diameters and tolerances. Many industrial and government standards exist for the production of pipe and tubing. The term "tube" is also commonly applied to non-cylindrical sections, i.e., square or rectangular tubing. In general, "pipe" is the more common term in most of the world, whereas "tube" is more widely used in the United States.

Both "pipe" and "tube" imply a level of rigidity and permanence, whereas a hose (or hosepipe) is usually portable and flexible. Pipe assemblies are almost always constructed with the use of fittings such as elbows, tees, and so on, while tube may be formed or bent into custom configurations. For materials that are inflexible, cannot be formed, or where construction is governed by codes or standards, tube assemblies are also constructed with the use of tube fittings.

Pipe was a Belgian automobile manufacturer founded by the brothers Alfred and Victor Goldschmidt. The company was also known as Compagnie Belge de Construction Automobiles.

In 1900 they presented their first car in Brussels under the name Pipe. This model was similar to cars made by Panhard & Levassor. This Pipe car was powered by a two-cylinder engine.

In 1901, a sporty model was made, the Pipe 15 CV, with a four-cylinder engine. This model was a good design to use in racing, and was used in the Paris to Berlin race. Pipe also built cars with more powerful engines, such as the Pipe 90 CV from 1903, and the Pipe 60 CV from 1904. The latter model had a 13.5 litre four-cylinder engine.

In 1907, over 300 cars of the types 28, 50 and 80 CV were sold. Because of this, Pipe became one of the largest Belgian car manufacturers. Pipe cars were not only sold in Belgium, but they were exported to many different countries.

During the First World War, the factory was partly destroyed. Only in 1921 did it resume car manufacture. In that year, Pipe presented two new models, with 3.0 and 9.0 litre, but these models were presented badly. The management decided to switch to the manufacture of trucks instead.
