A
hose is a flexible, hollow tube that can carry fluids from one place
to another. It's cylindrical in shape and is designed based on its
application and power to perform. Factors that come into hose
designing include size, weight, pressure rating, length, coilhose or
straight hose and chemical compatibility. Hoses are made from one or
combining many different materials together such as nylon, PVC,
polyethylene and natural rubbers.
Quality
flexible hoses are supplied to pharmaceutical, petrochemical,
chemical, food and beverage and textile industries. The composition
of various hoses differs a lot depending on its kind, for example a
food
quality hose
and a pharmaceutical hose will be made of entirely different
material. There's a lot of competition between hose
manufacturers
to get the best deals with companies that regularly need hoses,
couplings and related products in their day to day activities.
Different kinds of hoses have different kind of inner and outer
structure and are made of material best suited to their
application/purpose. For example, a petrochemical
hose
that is used by tank trucks, petrochemical stations etc. to carry
petroleum products from one place to another under pressure, suction
and gravity flow should be lightweight (at least half the weight of a
regular rubber hose) and its aromatic content should never go above
40%. The engineers of hose manufacturing companies discuss with their
clients and identify and assess options keeping in the mind the
conditions at hand before providing with the right hose using
approved and industry standard components.
Other
different kinds of hoses include silicone hose. They find use in the
food and beverage industries, medical and dairy industries among
others. Silicone is kind of a high purity platinum and it is the main
component of the tubing. PVC hoses are however the kind of hoses that
find usefulness in both industries and household applications. PVC
hoses with a polyester thread are very reliable at working under high
pressures. Being extremely flexible thereby allowing smooth flow of
fluid through the cross section of the hose, PVC hoses are slowly
become very popular. They are very suitable for handling industrial
fluids through air and water lines. But it must be ensured that the
hoses are made from PVC materials of low toxicity that has been
approved of contact with food materials and drinks. PVC hoses are
resistant to most liquids although the reason for its widespread use
is mainly because PVC is the only transparent hose material around.
Steam hose is another kind of hose used for steam applications that
operate in high temperatures. They are highly useful while high
pressure cleaning, streilising, pipe defrosting and fire snuffing.
A
new innovation in hose manufacturing is the production of composite
hoses. It's an unique kind of hose consisting of spirally bound plies
of thermoplastics and films put together by wire helices. The hose
has high radial and longitudinal strength which prevents the contents
from escaping. Composite hoses are constructed in such a way so as to
make its wall highly corrugated. This gives a high amount of
flexibility to the hose and allows to be easily lengthened under
pressure as opposed to rubber hoses. Both composite and rubber hoses
have similar uses but the former are much more lighter and flexible
which makes its a preferred choice over rubber hoses. Though among
rubber hoses, FEP
lined hose
whose inner tube is made of Chemofluor is similar to a composite hose
in terms of usefulness. This kind of hose employs C-Flex tubing made of a specialized thermoplastic elastomer that caters to the
needs of many different industry purposes.
