A hose (or hose pipe) is a hollow tube designed to carry fluids from one location to another. Hoses are usually cylindrical in shape, with a circular cross section; they are all flexible, though the flexibility (or rigidity) depends on the composition of the material from which they are made.
Hose design is based on a combination of application and performance. Common factors are Size, Pressure Rating, Weight, Length, Straight hose or Coil hose and Chemical Compatibility.
To achieve a better pressure resistance hoses can be reinforced with fibers or steel cord. Commonly used reinforcement methods are braiding, spiraling, knitting and wrapping of fabric plies. The reinforcement increases the pressure resistance but also the stiffness. To obtain flexibility, corrugations or bellows are used. Usually circumferential or helical reinforcement rings are applied to maintain these corrugated or bellowed structures under internal pressure.
Hoses are made from one or a combination of many different materials. Applications mostly use nylon, polyurethane, polyethylene, PVC, or synthetic or natural rubbers, 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 include PTFE (Teflon), stainless steel and other metals.
Hoses can be used in water or other liquid environments or to convey air or other gases. Hoses are used to carry fluids through air or fluid environments, and they are typically used with clamps, spigots, flanges, and nozzles to control fluid flow. All of us have seen hoses being used in gardens. A similar application is to water crops in farms, for drip irrigation. And firefighting would be impossible without fire hoses. There are several other places where hoses are used: - in chemical and pharmaceutical laboratories, in air conditioning systems, and many more. The list is practically endless.
