UNDERGROUND FUEL TANKS- Application of 100% Solids Polyurethane Coatings
Since 1975 there have been over 300,000 cathodically protected, underground steel fuel storage
tanks installed in the United States and Canada !he tanks in Canada "ere designed according to
the Under"riter #aboratories of Canada standard S$031 !he %a&ority of the '%erican tanks
"ere built according to the S!()*3 standard of theSteel !ank (nstituteof #ake +urich, (# or the
Under"riters #aboratoriesU#17$
-irtually all of these tanks have been coated "ith 100. solids polyurethane coating !he
a%ount of steel coated is in e/cess of over 150,000 %illion suare feet !he design of the syste%
has been so effective that, to date, there have been ero failures reported as a result of e/ternal
corrosion of the tanks !he si%ple design involves a dielectric coating 2usually 100. solids
polyurethane, nylon bushings 2to electrically isolate the tank fro% the piping and sacrificial
anodes
!he fabricators of the S!()*3 tanks continue to use 100. solids polyurethane coatings and offer
a 30 year "arranty against e/ternal corrosion
' %ost recent develop%ent in underground fuel storage tank coatings is the use of 100. solids
polyurethane coatings in replacing the e/isting 4* 2fiber)glass reinforced polyester
technology !hick 2100 %ils or 6500 %icrons 4* coatings have been for a long ti%e the onlytechnology used for the e/ternal protection of fuel steel tanks "hen there are no anodes attached
o"ever, both theSteel !ank (nstituteand the Under"riters #aboratorieshave recently tested
and approved that a 70 %ils 21750 %icrons thick 8special designed8 100. solids polyurethane
coating can outperfor% in every aspect a 100 %ils 26500 %icrons thick 4* coating
!he 4* technology deals "ith aardous solvents, styrene, glass fibers, and very long curing

Single-Wall Fiberglass Tanks:FRP Single-Wall Tanks are 100% corrosion resistant inside and
outside and are built to be compatible with all petroleum products.
Compatibility:
The CSI fiberglass tank wall is composed of premium resin, glass and a specially treated silica. This
composite matrix is compatible with:
gasoline
jet fuel
av-gas
motor oil
kerosene
diesel fuel
fuel oil
ethanol and/or methanol blends
oxygenated motor fuels alcohols
alcohol-gasoline blends
Capacities range from 550 to 50,000 gallons and are available in diameters from 4' to 12'.
Quality manufacturing:
Tank walls and specially designed ribs form a structural system that has earned the UL 1316. CSI tanks
are built from the inside out on a rotating mandrel. Application of resin, glass, and specially treated silica
are precisely metered onto the mandrel which is controlled by acomputer,custom designed to
manufacture underground tanks. Because of this process, the inside surface is very smooth and free of
surface variations which eliminates air inhibited surface cure problems associated with other methods.
Fiberglass Tanks Simply Will Not Rust inside or out:
And thats what you need to know when comparing fiberglass underground storage tanks and
underground tanks made from steel.
After nearly 250,000 installations since the early 1960s, not a single leak has been attributed to internal
or external corrosion.

Accessories:Turbine Enclosures
Overview
Fiberglass Turbine Enclosures provide access to critical equipment and serve as a termination point for
piping.
Long-term performance:
Our turbine enclosures are fiberglass a proven material for long-term performance. Compared to other
unreinforced plastics and HDPE products, the rigid fiberglass construction minimizes deformation during
backfilling to help assure liquid-tight seals at fitting penetrations.
Installation:
Turbine enclosures must be mounted on top of a secondary containment collar. Primary piping is installed
from the submersible pump to the dispenser. In the event of an accidental spill from the primary piping,
the spilled product will drain into the turbine enclosure and accumulate in the secondary containment
collar. The secondary containment collar serves as a basin to allow early detection of leaks of thesubmersible pump or the product piping.
When there is concern about the ingress of water at the collar/turbine enclosure
seam, the turbine enclosure should be sealed to the secondary containment collar at the jobsite.
Containment Solutions provides an alcohol compatible adhesive kit to make this connection. Continuous
electronic monitoring of the secondary containment collar should be used to warn the operator of the
accumulation of petroleum product before the liquid level rises above the collar/turbine enclosure seam.
Specifications:
Turbine enclosures are available in 42" and 48" diameters with a minimum 2' length.
To accommodate deeper burial depths, longer turbine enclosures are available in 1' increments. The
turbine enclosure can be trimmed at the jobsite to adjust for the final burial depth.
Note: For high groundwater conditions at or above subgrade, a sealable or watertight turbine enclosure
should be used to prevent water infiltration.
Special Installations:
When a tank will be equipped with more than one turbine enclosure or manway riser, the tank may
require special installation (deeper burial, additional anchor straps, etc.). Contact Tank Technical Support
for specific installation details.
Warning: a turbine enclosure constitutes a confined space. Never enter a turbine enclosure without
proper training and OSHA-approved equipment.

Accessories:Fiberglass Secondary Containment Collar
An optional secondary containment collar provides a containment area for spilled liquids, as well as a
location for the leak-monitoring sensor.
Installation:Collars can be installed around other tank fittings and accessories, where space permits.Collars are constructed of fiberglass and are available in 42" diameter (with 22" manways) and 48"
diameter (with 22" and 30" manways).
The secondary containment collar is integrally attached to the tank top to provide a watertight seal. The
collar is factory installed and tested prior to shipment. Another collar leak test should be performed at the
jobsite by the installing contractor. See Containment Solutions installation instructions for details.
Leak testing:The secondary containment collar must periodically be tested for leaks at least once
each year or after collar maintenance is performed by adding water to the collar above the tank top.
The secondary containment collar must be continuously monitored with an electronic sensor for potential
spills or piping leaks.
Secondary containment fitting:
A 6" FRP threaded secondary coupling is concentrically positioned around
the 4" NPT primary tank fitting. The secondary containment coupling is surface-mounted onto the tank
and does not penetrate the outer wall. To directly monitor the cavity between the primary and secondary
pipe, a fitting with an access port should be installed.
Accessories:Anchoring Systems
-

12/24
Deadmen:
Containment Solutions can provide deadmen anchors and turnbuckles for selected models
of tanks. Deadmen anchors provide a means to prevent installed fiberglass tanks from floating out of the
ground when the tank installation is subject to ground water around the tank. Deadmen anchors, when
used with CSI fiberglass hold-down straps and other CSI or contractor supplied hardware and installed
according to CSI installation instructions, prevent tank flotation and cost less than a concrete pad under
the tank.
Turnbuckles:
The CSI deadmen and turnbuckles can usually be shipped with 4', 6' and 8' tanks at no additional
charge. Deadmen are available in various lengths and are designed with and without eyebolts. Ask for
"Deadmen Anchors and Turnbuckles" publication to select the proper deadman for a particular tank size.
Split-Strap Anchor System:
Containment Solutions can provide a split-strap anchor system for 6', 8' and 10' diameter Single-Wall
Tanks. The split-strap anchor system provides a method to attach and tighten the tank anchor straps todeadmen or to an anchor pad without entry into the excavation. The split-strap anchor system is safer
and less costly than traditional methods that require shoring or other hole stabilization techniques to allow
entry into the excavation.
Fiberglass Anchoring Straps:
When mechanical anchoring is specified, fiberglass anchoring straps are available for all single-wall
tanks.

(variable length, 42" or 48" IDs), an FRP reducer (42" or 48" IDs) with an oval flanged manway(23"x29" IDs), a flat gasket, SS bolts with non-galling silicone-bronze nuts (or optional bolt ring),
and an oval FRP lid with handle. The reducer opening must be large enough (minimum 28") to
allow for the removal of a 22" manway lid. The lid OD must be small enough to be removed
through a 36" street box. The enclosure body must be capable of joining to the 42" or 48"
diameter secondary containment collar with a leaktight adhesive joint. The reducer with oval
flanged manway must be capable of joining to the enclosure body with a leaktight adhesive joint.
With the lid installed, the assembly must provide a watertight seal with water up to 7' over the lid.
The lid may be supplied with an optional 6" NPT fitting with plug which can be used as an
observation port.

to bond the reducer to the enclosure body) and Sections I, J, K and L for the field installed fitting
kits (for electrical and plumbing connections to the turbine enclosure).
K.Turbine Enclosure Adhesive Kit
(Kit AD) - When properly installed and cured, the adhesive kit provides a watertight seal to
prevent the ingress of water. The adhesive kit includes 1/2 gallon of adhesive in a one gallon
capacity can. The kit also includes catalyst (hardener), a wooden mixing stick, a three inch wide
plastic putty knife, 60 grit sandpaper, and installation instructions. One adhesive kit is required for
each turbine enclosure; the watertight and sealed turbine enclosures require two kits.
L.Field Entry Boot (Model FEB-3 or FEB-4) The FEB-3 or FEB-4 is designed to interface with 3"
or 4" nominal OD FRP pipe.
M.FRP Coupling Kit (Kit FC-3 or FC-4) is designed to interface with 3" or 4" nominal OD FRPpipe. The coupling ID is tapered at both ends.
The two-piece coupling is constructed of fiberglass reinforced plastic and is field-installed using
the supplied adhesive. Both pieces of the fitting are threaded together to hold the fitting in
position while the adhesive cures.
Kit FC-3 or Kit FC-4 includes one 3" or 4" nominal ID FRP coupling, adhesive, catalyst
(hardener), plastic mixing stick and applicator, 60 grit sandpaper, and installation instructions.
The contractor must provide the hole saw (4-1/2 or 5-1/2 inch OD) or reciprocating saw to cut thehole in the turbine enclosure prior to installing the FRP coupling.
N.Electrical Coupling Kit Kit EC-1 is designed to interface with one inch steel electrical conduit.
The two-piece coupling is constructed of steel and is field installed using the supplied adhesive.
Both pieces of the fitting are threaded together to hold the fitting in position while the adhesive
cures.
Kit EC-1 includes two (2) one inch steel couplings, adhesive catalyst (hardener), plastic mixing
stick, 60 grit sandpaper, and installation instructions.
The contractor must provide a two inch hole saw or reciprocating saw to cut the hole in the
