You must have seen a hose being used to water the garden, or to fill water from a tap to a drum in water scarcity areas. You might even have used one to wash your backyard or front yard. That flexible hollow tube conveys not just fluids, but also gases in certain cases as when a patient needs to be put on oxygen. However, are you aware of the kinds of hoses in normal use, or how a hose differs from a pipe?
Main Differences Between Hose and Pipe
Some people use the terms hose and pipe interchangeably. Till fairly recently, people called it a hose pipe. The principal differences between a pipe and a hose are the rigidity, and the end use. That is why pipes are usually made of metal, ceramic, concrete, or fiberglass; though modern drain pipes are made of a very flexible material which permits them to pushed through soft soil, and expand when in place. Though, both are normally measured by their inner diameter; pipes are meant to last a lifetime, or at least for very long periods. Hoses need to be replaced at specified intervals to assure security.
Materials used to manufacture hoses: Hoses might be made of natural fibers like rubber, or be rubber lined; or synthetic fibers like nylon; polymers like polyvinyl chloride (PVC); polyethylene like cross-linked polyethylene (XLPE); and polyurethane for food grade hoses used to transport milk, juices, and other edible materials like cooking oils.
Why Would Anyone Require Industrial Hoses?
You would be astonished to learn that there are more industrial uses of hoses than domestic ones. Industrial grade hoses are the extra high pressure hoses, pneumatic tool hoses, LPG hoses, sand blast hoses, hydraulic hoses; carbon free hoses, car wash hoses, CNG hoses, and high temperature hoses. They are used in as diverse industries as transportation — in vacuum brakes of railway coaches and wagons, or supply of CNG or LPG in automobiles; food processing; mining, and heavy earthmoving vehicles; cement manufacture; oil and petroleum industry; and steel manufacturing.
Always Use These Parameters When Ordering a Hose
Most of the parameters like size — length and diameter; preferred materials for manufacture; degree of flexibility required; and heat resistance will depend on end use, and what needs to be conveyed through the hose. Other factors like durability, pressure, connections and fitments required, wire or textile braiding for strengthening, volume and velocity of the material to be conveyed, and whether an inner tubing is required will flow from that.
Look for quality control measures used, the kind of rigorous testing the manufacture puts their products through, and the safety parameters which are guaranteed.
