What Does tube Mean
From the Latin tubus , a tube is a hollow piece that is usually cylindrical in shape and that, in general, is open at both ends. The union of multiple tubes allows to create a pipe , a conduit that allows the transport of water or other liquid.
The tubes can be made of various materials, according to technical and economic needs. Iron, steel , copper, lead, and PVC are some of the most common materials.
A pipe, on the other hand, can be built from three basic manufacturing methods: seamless (helps contain pressure thanks to its homogeneity), longitudinal seam (a straight weld that follows a generatrix) or helical seam (the welding is done in a spiral).
The pipes allow the transfer of drinking water to residential houses or facilitate the evacuation of sewage or sewage. Some pipelines have specific names: when the pipeline carries oil, it is known as an oil pipeline , while the pipeline that carries gas is called a gas pipeline .
However, we should not overlook the fact that, at a 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 toothpaste, gel, glue, paints or ointments.
Those are also characterized by being closed with a screw cap and because in order to obtain the material stored inside, what you have to do is press them.
But there are more types of tube. Thus, for example, in the scientific field there is talk of what is called a test tube. This is defined by being a glass tube open at the top that allows me to carry out different tests and chemical tests.
In the same way, we must not forget the so-called intestinal tube. This is a word that is used in the field of biology and veterinary medicine to refer to the set of intestines that a specific animal has.
Another variety of tube is the one used in the automotive field. In this sector we speak of the so-called exhaust pipes. These are the cylindrical type that have both cars and motorcycles or mopeds and that are used to evacuate, from the inside of them to what would be the outside, the set of combustion gases that these vehicles generate. These pipes usually generate noise pollution, so it is advisable to install a silencer.
In water sports such as surfing , a tube is a maneuver that is performed based on the particular characteristics of certain waves. When the wave hits the bottom of the breaker, it creates a hollow space; there the athlete introduces his board on board. In the event that the tube breaks, the person may suffer some kind of physical harm.
Finally, the notion of tube is used as a synonym for valve in the field of electronics . Valves or tubes, therefore, are elements that are part of radio and television sets.
