Photos show the tank shapes but are not
necessarily the 200 gallon size.
200 gallon poly tanks
in several shapes including vertical, cone bottom, and
horizontal. Some of our 200 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. Our
200 gallon vertical tanks are also available made from
Polypropylene and PVDF for those applications that require
Most of our
200 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
standards set by ASTM D 1998. The ASTM standards were
not written to apply to other shapes of tanks.
