Photos show the tank shapes but are not
necessarily the 1200 gallon size.
1200 gallon poly tanks
in several shapes including vertical, cone bottom, and
horizontal. Some of our 1200 gallon tanks are
available in more than one type of plastic.
Polyethylene is the most widely used plastic resin for
making storage tanks due to its relatively low price and
good chemical compatibility. The polyethylene used is
HDPE. HDPE (High Density Polyethylene) is sometimes
conveniently but incorrectly referred to as HDLPE.
Specific Gravity Ratings:
Most of our
1200 gallon poly tanks are available in more than one
specific gravity rating. We have some tanks that are
rated for "Water Only", while others are rated at 1.5
specific gravity, 1.9 specific gravity or even 2.2 specific
The Vertical Polyethylene tanks meet wall thickness
standards set by ASTM D 1998. The ASTM standards were
not written to apply to other shapes of tanks.
If you are selecting a
tank for chemical storage be sure to click on "Storage
Applications" on the menu. You can select the chemical
you are storing and find out the chemical compatibility with
each kind of plastic and the materials of construction of
