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

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

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.
