Hose

From Wikipedia, the free encyclopedia

A hose is a hollow tube designed to carry fluids 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). In recent years hose are manufactured from special grade polyethylene (specially LLDPE).

Hoses are used in water or other liquid environments to convey air or other gases; they are used in air or other gaseous environments to convey liquids. Hoses are used to carry fluids through fluid environments, and they are typically used with clamps, spigots, and nozzles to control fluid flow.

Polyethylene hose and tubes are made in accordance to American Society of Agriculture Engineer (ASAE), Bureau of Indian Standards (ISI), ISO and American Standard for Testing and Materials (ASTM).

Specific applications include the following:

• A garden hose is used to water plants in a garden or lawn, or to convey water to a sprinkler for the same purpose.
• A Tough Hose is used to water crops in Agriculture for drip irrigation
• A firehose is used by firefighters to convey water to the site of a fire.
• Air hoses are used in underwater diving (e.g., scuba diving) to carry air from the surface or from air tanks. (See also Snorkel.)
• In architecture, metal or plastic hoses (usually called pipes) are used to move water around a building; air ducts are used to move air around (see Air conditioning).
• Automotive hoses are used in automobiles to move fluids around for use in cooling, lubrication, and/or hydraulics. 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.
• In chemistry and medicine, hoses (usually called tubes) are used to move liquid chemicals or gases around.
• In business, to hose means to take someones money.

Some of the more notable manufacturers of drip hoses are:

• Jain irrigation Systems (Jalgaon, India)
• Chapin Watermatics (New York, U.S.A.)
• Aquaris Brands, Inc (USA)
• Eurodrip (Greece)
