- Hose (tubing)
A hose is a hollow tube designed to carry
fluid s from one location to another. Hoses are also sometimes called tube or "pipes" (the word "pipe" usually refers to a rigid tube, whereas a hose is usually a flexible one), or more generally "tubing". The shape of a hose is usually cylindrical (having a circular cross section).Hose design is based on a combination of application and performance. Common factors are Size, Pressure Rating, Weight, Length, Straight hose or Coilhose and Chemical Compatabiltiy.
Hoses are made from one or a combination of many different materials. Applications mostly use
nylon ,polyurethane ,polyethylene ,PVC , or synthetic or naturalrubber s, based on the environment and pressure rating needed. In recent years, hoses can also be manufactured from special grades of polyethylene (LDPE and especially LLDPE). Other hose materials includePTFE (Teflon ),stainless steel and other metals.Hoses can be used in
water or otherliquid environments or to conveyair or othergas es. Hoses are used to carry fluids through air or fluid environments, and they are typically used with clamps, spigots,flange s, andnozzle s to control fluid flow.Specific applications include the following:
* Agarden hose is used to water plants in agarden orlawn , or to convey water to asprinkler for the same purpose.
* A Tough Hose is used to water crops inagriculture fordrip irrigation
* Afire hose is used byfirefighter s to convey water to the site of afire .
*Air hose s are used in underwaterdiving (e.g.,scuba diving ) to carry air from the surface or fromair tank s. (See alsoSnorkeling .) Industrial uses for operating flexible machinery and worktable tooling sush as pneumatic screw drivers, grinders, staplers, etc.
* In building services,metal orplastic hoses are used to move water around abuilding ; whilstair duct s are used to move air around (seeair conditioning ). They can also be used to take out vibration, and thermal or settlement movement.
* Automotive hoses are used inautomobile s to move fluids around for use in cooling, lubrication, and/orhydraulics . Hoses are also used to convey pressure or vacuum signals to control circuits or gauges, as well as conveying vacuum to heating, cooling, brake, and/or locking systems.
* Inchemistry andmedicine , hoses (usually called "tubes") are used to move liquid chemicals or gases around.
* Inbusiness , to hose means to take someone's money.
