Applications
By Industry for Basket Strainers
|
|
|
|
|
| |
| 1 |
Water
Handling |
 |
|
| This
is probably the
greatest area of usage for basket strainers. They take sand, gravel, etc.,
from lakes, streams, and wells which might damage or clog equipment. They
take leaves, insects, feathers, etc. from cooling tower water where the
system is open to the atmosphere. They strain out hair and lint from large
swimming pools before the water passes to a filter. Basket strainers are
an important part of desalinization equipment where they take out dirt,
or other unwanted matter from the water before it is treated for salt removal.
Spent waste water from industrial use is frequently passed through a basket
strainer to take out material which should not go into a sewer or waterway. |

Food
Industry |
|
|
| Basket
strainers are used to remove traces of grape skins and seeds from wine
and to remove bits of pulp, skins, or other unwanted matter from fruit
juices. They are used to take out lumps from chocolate syrup
and wax from honey. The Baking Industry strains bone and gristle from molten
lard with basket strainers and also uses them to remove bits of dough,
seed, etc., from water they discharge into sewer systems to conform to
environmental regulations. |

Marine
Industry |
|
|
| Basket
strainers are used in
the Marine Industry for many purposes. One of the most important is handling
sea water in cooling lines, fire control lines, sanitary lines, and general
cleaning lines. This water comes from outside the ship and can contain
a good deal of undesirable matter. Strainers are used on board ships to
clean fuel, hydraulic and lubricating systems. |

Process
Equipment |
|
|
| Expensive
equipment is often protected against damage from
scale, dirt, by-products, etc., or from costly shutdown due to the presence
of these materials by installing a basket strainer ahead of them in the
line. Heat exchangers, condensers, and pumps use strainers on their intake
sides. Flow meters and spray nozzles are kept from clogging by basket strainers. |
|
| 5 |
Paint,
Ink, and Latex |
|
|
| The
presence of
"fish eyes" (lumps of un-disolved resin), skins, and clumps of pigment
is a perpetual problem. They are hard to detect and can spoil a batch run.
Basket strainers are used to remove all of them. |
|
| 6 |
Electric
Utilities |
|
|
| Strainers
are used in the
Power Industry to clean water and to protect equipment as descried above.
They also screen transformer oil to avoid clogging of the circulating lines. |
|
| 7 |
Pharmaceuticals
and Cosmetics |
|
|
| Ointments,
lotions and similar products which may contain clumps of undispersed or
undissolved matter are pumped through basket strainers. In the manufacture
of lipstick, for instance, unwanted lumps can ruin the product. |
| |
| 8 |
Refrigeration |
|
|
| Brine
lines can pick up dirt or corrosion products from action of the salt. Basket
strainer form an important part of the piping systems in refrigeration
plants to keep the brine clean. |
| |
| 9 |
Petroleum |
|
|
| Basket
strainers clean
unwanted material from petroleum products ranging from crude oil to gasoline.
A specific case is fuel oil, which can contain gums or tars or other dirt
which can plug the nozzles of an oil burner. Every industrial oil burner
is equipped with a basket strainer to screen these out. Strainers are used
in similar ways in refineries and in oil handling operation to keep undesirable
material away from pumps, meters and other equipment. |
| |
| 10 |
Pulp
and Paper |
|
|
| The
problem of
unseen lumps in coatings in the paper industry is an ever present one.
Smooth paper finishes require that coating be free of undispersed clumps
of pigment. Basket strainers in the coating lines catch and hold the lumps.
They are also used to clean trances of pulp or paper from white water effluent
before it is discharged into the environment. |
| |
| 11 |
Ceramics |
|
|
| Just
as the
paper industry needs lump free coating the Ceramic Industry does also.
The presence of unwanted solid particles in glazes, for example, can mean
rejection of a product. Basket strainers are installed just ahead of glaze
spray equipment to prevent this. |
| |
| 12 |
Transportation |
|
|
| A basket
strainer installed
on a tank truck or rail car which must dispense liquids, can catch solid
material which is not wanted. Many chemical products undergo changes in
storage or transport which result in solid residues. The presence of solids
in liquid fertilizers or pesticides, for example, can cause clogging of
spray equipment. For this reason, many tank trucks and cars are equipped
with strainers. |
| |
| 13 |
Chemical
Processing |
|
|
| This
industry is
perhaps the largest user of basket strainers. There are innumerable areas
where the presence of a basket strainer means a cleaner product, protection
of equipment, or simple separation of solids from liquids. There
is scarcely a chemical operation involving liquid flow which cannot be
improved or guaranteed longer running life by installation of a basket
strainer in the line. is perhaps the largest user of basket strainers.
