From Latin tubus, a tube is a hollow piece which usually has a cylindrical shape and that is usually open at both ends. The union of multiple tubes allows to create a pipeline , a conduit that allows the transport of water or other liquid.
The tubes can be made of various materials, according to the technical and economic needs. The iron, the steel , copper, lead and PVC are some of the most common materials.
A pipe, on the other hand, can be constructed from three basic manufacturing methods: seamless (helps contain pressure thanks to its homogeneity), with longitudinal seam (a straight weld that follows a generatrix) or with helical seam (welding is done in a spiral).
The pipes allow the transfer of drinking water to residential homes or facilitate the evacuation of sewage or sewage. Some pipes have specific names: when the pipeline carries oil, it is known as pipeline , while the pipeline that carries gas is called pipeline .
However, we must not overlook the fact that, at the colloquial level, the term tube is also used to refer to an elongated and cylindrical container that usually contains different types of gels inside. Specifically, we find tubes of dentifrices, gum, glue, paints or ointments.

Another variety of tube is the one used in the automotive field. In this sector we talk about the so-called exhaust pipes. These are the cylindrical type that have both cars and motorcycles or mopeds and are used to evacuate, from inside them to what would be the outside, the set of flue gases generated by these vehicles. These tubes usually generate noise pollution so it is advisable to install a silencer.
In the watersports As the surfing , a tube is a maneuver which is made from the particular characteristics of certain waves. The wave, when hitting the bottom of the breaker, generates a hollow space; there the athlete is introduced on board his board.
