Plastic Tanks: Plastic Storage Tanks
|
|
Plastic Tanks up
to 20,000 gallons have replaced tanks of many other
materials (especially fiberglass) over the last decade.
Plastic tanks are especially good for storing water and
most chemicals including
chlorine, bleaches and acids.
|
One advantage that Plastic Tanks have over storage tanks
made from most other materials is much lighter weight.
The weight saving means lower costs and greater ease of
transport, handling and positioning. Tanks made from
plastic are usually less likely to react to the liquid
which is stored in them. The FDA has approved several
polyethylene resins for holding drinking water and food
products. Perhaps the most significant advantage that
plastic storage tanks have is lower cost. In sizes up to
about 20,000 gallons, tanks made from polyethylene are
significantly less expensive to purchase and deliver
than are tanks made from most other materials.
|
With the use of modern plastics, the lifespan of a
properly used plastic storage tank can rival or exceed
the life of most other tanks. Additionally, there are
virtually no maintenance costs associated with tanks
made of plastic.
|
There are many types of plastic that can be used to make
storage tanks. Polyethylene is by far the most common.
Tanks made from a high quality polyethylene resin will
be strong, durable and reliable over a long time. There
are some chemicals that do not store well in
Polyethylene and for those substances, other plastics
like polypropylene or kynar may be more suitable
|
When considering which plastic tank to use, you should
know that they are rated based on the 'specific
gravity' of the
substance they are designed to hold. To put it simply,
tanks with a higher specific gravity rating will have
thicker walls and will be designed for heavier duty use
when compared to another tank made from the same
material but with a lower specific gravity. As an
example, a polyethylene tank designed with a specific
gravity of 1.9 will be a stronger tank than a similar
tank with a specific gravity of 1.5 or 1.2. Because more
resin is required to produce tanks with a higher
specific gravity rating, the cost usually rises along
with the specific gravity rating of a tank.

Plastic storage tanks are available in an extremely wide
range of sizes and shapes. At Bailiff Enterprises, we
offer nearly all of the popular shapes and our sizes
range from 8 gallons to 20,000 gallons. Tanks come in open
top, closed
top and dual containment versions. Most plastic storage
tanks are round but we also produce rectangular tanks.
|
Double wall plastic tanks are
a particular specialty of Bailiff Enterprises. We
offer them in sizes up to 10,000 gallons of capacity for
the inner tank.
