SIZES FROM 80 TO 12,500 GALLONS
All tanks are constructed to the
requirements of the ASME Code.
These ASME Code tanks are available
at 125,150 &160 PSI working pressure.
Consult factory for ASME Code tanks
that have greater or lesser working
pressures with special configurations
or materials.
LINING AND COATINGS
Each lining and coating has particular
capabilities and limitations. Thorough
investigation on the service life of steel
tanks with protective coatings or linings
has led to the recommendation of the
following linings:
n
Glass Lined — All internal surfaces
exposed to water are glass lined per
ASME HLW Code procedures.
n
Cement Lined — Cement lining
consists of a specially formulated
cement applied over the interior of
the vessel. Cement lined tanks are
recommended when storing water
at 180°F or higher.
n
Epoxy Lined — The application of
specially formulated epoxy makes
this lining suitable for cold or hot
water storage.
Please consult the factory for
recommendations on the uses of linings
for
specific applications. All tanks
receive one prime coat of paint on
external surface.

unusual applications that may require

FACTORY INSULATION OPTIONS
Factory Jacketed and Insulation
n
INSULATION — Entire tank is surrounded with high-density fiberglass insulation to reduce costly heat loss; non-sagging and vermin-
proof. To meet or exceed the thermal efficiency and/or standby loss requirements of the U.S. Department of Energy and current edition
of ASHRAE/IESNA 90.1, depth of insulation cavity requires use of remote bulb-type tank temperature control and thermometer.
n
CABINET — Heavy gauge steel with high quality powder coat paint provides additional insulating qualities for greater energy savings.
n
Adds 6˝ to the diameter of the tank.
