Double-Wall Tanks from Containment Solutions

Why our tanks are your best investment.The fiberglass underground storage tank owes its very existence to theshortcomings of steel tanks — and their resulting environmentalproblems.

In the early 1960s, the American Petroleum Institute challenged us (we were then known as the SpecialProducts Division of Owens-Corning) to develop a rustproof underground storage tank that would be safe andstrong enough to satisfy the petroleum industry’s most stringent long-term storage demands.

Our engineers accepted the challenge and pioneered the underground fiberglass tank technology. The majoroil companies responded to our achievement by specifying fiberglass tanks for approximately 95% of theirunderground fuel storage installations. Their keen awareness of the limitations of a steel tank in a corrosiveenvironment and their confidence in fiberglass tank technology helped us earn a reputation for safe, rust-free,long-term underground storage in approximately 250,000 installations over the last 30 years.

Along the way, we’ve earned a leadership position in this industry. Our pioneering design work resulted in theUL 1316 specification which governs fiberglass tank manufacturing.

As the inventors of fiberglass underground storage tank technology, many of the basic patent standards beganwith Owens-Corning and continue with Containment Solutions today and in the future.

Processes

The product of precision engineering and forward thinking.The process by which our fiberglass tanks are manufactured speaks volumes about their quality, integrity,safety and longevity.

Since the very first non-corrosive tank was designed back in the 1960s, we have maintained the highest qualitystandards and have leveraged promising technologies to engineer and build the world’s premier fiberglassstorage tank.

Our tanks are made on steel molds from the inside out.We use steel mandrels (cylindrical steel molds) and build our tanks from the inside out. Steel molds provideus with a firm and consistent surface upon which we apply materials to make our tank. The rotation of themandrel and the application of the materials are controlled by a computer, custom designed to manufactureunderground tanks. As the mandrel rotates, resin, glass and specially treated silica are precisely metered ontothe mandrel from above. The result is a closely controlled process and a very consistent tank wall compositionand thickness.

After the tank wall is made, its thickness is precisely determined. Aninstrument that magnetically senses the metal mold surfacethrough the fiberglass reinforced plastic laminate is used toaccurately measure the thickness of the laminate at many points allover the surface of the tank wall. This method of thicknessmeasurement with a metal mold is quick, easy and more exact thanthe ultrasonic methods used by other manufacturers.

Stronger tanks, inside and out.The inside-out approach to building the tank wall has some otheradvantages as well. The first layer of materials forms the insidesurface of the tank. Because of the smooth steel mold, the insidesurface of the tank is very smooth and free of surface variations.

The inside surface is not exposed to air as it cures, which eliminates the air inhibited surface cure problemssometimes associated with other methods. The result is a well cured and very smooth tank interior that willbe exposed to the fuel in the tank.

By applying materials to the outside of the tank, we can easily add additional thickness, reinforcing ribs,filament winding glass in tension, glass woven roving, glass mat, or any other materials in specific locationson the tank wall. With this capability, we use the most efficient materials in the most efficient locations to meetthe design requirements of the finished tank. Additional wall thickness is added exactly where it is needed.Ribs are applied in optimal locations, made in the most efficient shapes, and constructed of the most efficientreinforcing materials. If a different rib shape or height or location would be better, the form or the location ofthe rib can be changed. If the rib form shape was a part of the mandrel, these changes could not be madewithout changing the mandrel itself.

Engineered and tested corrosion resistance.The Containment Solutions’ tank wall is composed of resin, glass and a specially treated silica that togetherresult in a composite matrix that is compatible with petroleum products, including gasoline, jet fuel, av-gas,motor oil, kerosene, diesel fuel and fuel oil, and up to 100% ethanol and/or methanol blends and oxygenatedmotor fuels.

Containment Solutions pioneered and per-fected the use of a specially treated silica thatis a part of our laminate matrix. The additionof this material has been proven to increaseand improve the performance of our laminatein all fuels, including alcohols.

Our laminate has been thoroughly tested tomeet the requirements of UL 1316. Additionallong-term corrosion testing continues at ourResearch and Development Center. Thistesting is done in conditions that match actualinstallation conditions. This results in datathat can be used to accurately predict thelong-term properties needed for accurate tankdesigns. Data has been accumulated forcurrent fuels and blends as well as its effectson the laminate after a number of years. Thisdata includes tests on current fuels andblends and other oxygenates. We areconstantly testing new products that can bestored in our tanks in the future.

Our R&D Center never stops asking questions.We could never maintain our position on the leading edge of fiberglass tank design without anuncompromising commitment to research and development. Our newly expanded R&D Center gives us theability to look at new and promising ways to improve our products, expand our capabilities and better serveour customer’s ever-changing needs.

Our underground tank test pit helps us perfect our product.Containment Solutions is the only fiberglass tank manufacturer that studies tanks in all buried conditions andconfigurations. To do this, we constructed a full-scale test pit at our Conroe, Texas R&D Center, which allowsus to test various tank designs with different backfill materials, anchoring methods, groundwater conditionsand many other variables.

Our Line of Type II Double-Wall Tanks isRustproof.Fiberglass tanks simply will not rust— inside or out, on all four surfacesof the inner and outer tank.

That’s the reason ContainmentSolutions’ fiberglass tanks haveproven to be safe, cost-effectivecontainment solutions for petro-leum and related products. The factis, after nearly 250,000 installationssince the early 1960s, not a singleleak has been attributed to internalor external corrosion.

True Double-WallConstruction Means HighStrength.We build strength and quality intoevery double-wall tank from thebeginning.

Tank inner and outer walls andspecifically designed ribs acttogether to form a structural systemthat has earned the UL 1316 listingthat distinguishes this as a truedouble-wall tank.

Secondary ContainmentProvides 360˚ of Protection.You can count on total protectionfrom our double-wall tank.

Our tanks are available with dry orwet monitoring of the annular spaceand will detect leaks in inner andouter walls under all conditions.

Our Double-Wall Tanks deliver state-of-the-art protection.CSI’s advanced double-wall technology gives owners, municipalities, counties and states proven protectionagainst petroleum contamination of underground water supplies. In addition to our UL listing, our tankscomply with the American Petroleum Institute’s recommendation for secondary containment systemswherever underground tanks are located within 300 feet of underground water supplies.

As liabilities associated with leaking fuels soar, UL-listed fiberglass Type II Double-Wall Tanks for undergroundstorage applications provide you with your best long-term protection.

Don’t settle for less than the ultimate in risk management.Type II Double-Wall Tanks give you two levels of protection, so you have twice the assurance and twice therisk management that any single-wall tank can offer. The primary tank is designed to contain your fuel. In theunlikely event that there is a breach in this wall, the secondary wall is designed to contain your product andprevent a spill into the environment.

System testing assures you of product tightness.Continued assurance of the integrity of our double-wall tanks can be determined by testing at the jobsite –prior to and after installation – to prove the durability and product tightness of both the primary and secondary

tanks. With some competitive tanks, the secondary wallsor jackets cannot be tested after the tanks have beeninstalled.

Continuous monitoring and precision tank-testing capabilities are built in.Because it is comforting to be able to test the ongoingintegrity of any storage tank, CSI built into each of ourdouble-wall tanks both continuous monitoring andprecision tank-testing capabilities.

Our Type II Double-Wall Tanks provide a defined annular space to accommodate virtually any type of moni-toring method you choose — wet or dry. Our tanks can be supplied with a factory installed HydrostaticMonitoring System with a brine monitoring fluid. The brine is a dark green color preinstalled in the interstitialspace at the factory and is used to perform visual leak testing during shipment and at the jobsite.

We recommend the Hydrostatic Monitoring System because it offers a leakdetection capability that is superior to other methods. It constantly monitors 100%of both the inner and outer walls under all installed conditions. Most steel tanks donot offer this feature. The Hydrostatic Monitoring System can also double as aprecision tank test, which has been independently tested and validated to meet EPAprecision tank-testing requirements, able to detect leaks as small as 0.1 gallons perhour. The precision tank-testing procedure is easy to perform and consists of a fewsimple steps.

MonitoringHydrostatic Monitoring System helpsguard against leaks and liabilities.Containment Solutions recommends the HydrostaticMonitoring System for double-wall tanks because of itssuperior leak detection capability. By filling the cavitybetween the inner and outer tank walls with a non-hazardous liquid, hydrostatic pressure is continuouslyapplied to both the primary and secondary tank. Thissystem is capable of detecting tank leaks in either theprimary or secondary tank walls for all installedconditions.

The Hydrostatic Monitoring System, with a stand pipe,can also serve the dual function of a precision tank test.The system has been independently tested andstatistically validated to meet the EPA and National FireProtection Association’s criteria as a precision tank test.Using a stand pipe, the system has been shown to becapable of detecting leaks as small as 0.10 gallons perhour with a 99.9% probability of detection and less thana 1.2% probability of a false alarm.

All the fiberglass double-wall tanks in this brochure caninclude the optional fiberglass reservoir necessary forthe Hydrostatic Monitoring System.

The Hydrostatic Monitoring System providescontinuous leak detection while avoiding false alarmscaused by changes in product temperature, productlevel, tank deflection under loads, or groundwaterconditions.

Accessories Antifreeze MixturesIn areas where ambient temperatures or deliveredproducts may be subjected to freezing conditions, anantifreeze solution must be used with our HydrostaticTank Monitor to avoid potential tank damage.

Brine Antifreeze SolutionOur pre-mixed and blended calcium chloride solutionprovides freeze protection to -40˚F. This non-toxic brineantifreeze can be factory-installed into tanks measuringup to 10' diameter and 30,000-gallon capacity. Its colortracer helps detect hidden damage from shipping orjobsite handling.

Dry Annular SpaceContainment Solutions provides a factory-installed “drawstring” at the annular space monitoring fitting, toassist in positioning liquid sensors at the bottom of the annular space. If your tank is ordered with a dryannular space, but fitted with the optional fiberglass reservoir (instead of a monitoring fitting), the drawstringwill be positioned within the reservoir.

The HydrostaticMonitoring Systemis the best at leakdetection because

it’s continuouslymonitoring thecomplete innerand outer tank.

Monitoring

Footnotes:(1) Only monitors the portion of the inner wall which is in contact with liquid product.(2) Only monitors the portion of the outer wall which is submerged in groundwater.(3) With an inner wall leak, product can leak to the outer wall. Then, if the outer tank has an unknown leak, product will spill.(4) The vacuum or pressure pump can mask small leaks in the inner and/or outer tank wall. This pump is normally required to

compensate for pressure and vacuum losses caused by line losses or changes in product temperatures.(5) Does not monitor any portion of the outer wall.(6) If the outer wall has a larger leak than the inner wall, product may spill without accumulating in the annular space.(7) If the annular space is contaminated with product, residual fumes are difficult to remove.

ElectronicsContainment Solutions’ monitoring and inventory control components can be configured to satisfy a widerange of customer requirements.

Optional Containment Solutions’ components – control and switch panels, sensors, probes and gauges – areavailable for all double-wall, single-wall, compartment and oil/water separator tanks as well as for single ormultiple tank installations.

Tank Specifications

Standard Tank Notes1. The primary tank’s standard pipe fittings are 4" NPT half couplings. All tanks include one manway with

three or more primary tank fittings in the cover. All other primary tank fittings are mounted on the tank.Additional manways and tank fittings are available on a made-to-order basis.

2. Tank bottom deflector plates are standard under every manway and primary tank fitting.

3. An optional fiberglass reservoir for leak monitoring can be integrally bonded to the top of all 6' diameter and larger double-wall tanks. It includes a 4" NPT half-coupling fitting mounted on top of thereservoir, which allows access to the cavity between the inner and outer tank walls. On 6' diameter andlarger tanks with an optional fiberglass reservoir, the reservoir is positioned over the normal monitorfitting position and the tank will not include a separate monitoring fitting. The rib under the reservoir ishollow if the annular space is not factory filled with monitoring liquid.

4. For all double-wall tanks without a reservoir, a 4" NPT annular space fitting is included on the top of thetank for monitoring. It permits access to a hollow rib which accommodates the installation of liquidsensors.

5. Fiberglass reservoirs are not included on 4' diameter tanks. A contractor-supplied 4" diameter riser pipemust be inserted into the 4" diameter annular space fitting to serve as the tank’s reservoir. This riser pipemust be at least 2" longer than the electronic sensor.

6. All primary tanks must be vented. They areintended to be operated with fluid levels nohigher than the tank top. Fiberglass tanksare designed to be operated at atmosphericpressure only – except when using vapor-recovery systems – provided the pressure orvacuum does not exceed 1 psi on theprimary tank. Over-pressurizing the primarytank will result in tank failure. When ventingthe monitoring cavity between the inner andouter tank, it must be vented independentlyfrom the primary tank (annular spaceventing is required for all hydrostaticallymonitored tanks).

See pages 14-22 for standard tank data andconfiguration.

Tank Specifications

Made-to-Order Double-Wall TanksSuggested Fitting LocationsAlthough our standard double-wall tanks are designed to accommodate most storage applications, they canbe modified to include additional manways, tank-mounted fittings or other double-wall tank accessories.Made-to-order tanks require additional lead time for production and are more expensive to purchase.

The standard tanks are shown with tank-mounted fittings in the standard positions. Monitoring fittings,reservoirs, lift lug locations and anchoring strap locations can sometimes be relocated, but require specialapproval prior to any relocation.

In addition to the standard tank notes, the following notes apply:

1. The location of additional and/ormodified tank accessories should bereferenced by the numbered fittingposition between the ribs.

2. The primary tank’s standard pipefittings are 4" NPT half couplings. Alltanks require at least one manway.The manway cover should include atleast one fitting to facilitate futurevolumetric tank testing.

3. Specifying more or larger manwaysthan available on standard tanks mayalter the anchoring strap locations.These can often be relocated, butrequire special approval prior to anyrelocation. Larger manways alsorequire larger containment collars.

4. We recommend that all additional manway covers include at least one fitting to facilitate future volumetricprecision tank testing.

5. Tank bottom deflector plates are standard under every manway and fitting.

6. Monitoring fittings, reservoirs and lift lug locations can sometimes be relocated, but require specialapproval prior to any relocation.

Containment Collars

Optional tank accessories for secondary containment systems.

Fiberglass Secondary Containment CollarAn optional secondary containment collar provides a containment areafor spilled liquids, as well as a location for the leak-monitoring sensor.Collars can be installed around other tank fittings and accessories,where space permits. Collars are constructed of fiberglass and areavailable in 42" diameter (with 22" manways) and 48" diameter (with 22"and 30" manways) sizes.

The secondary containment collar is integrally attached to the tank topto provide a watertight seal. The collar is factory installed and testedprior to shipment. Another collar leak test should be performed at thejobsite by the installing contractor. See CSI installation instructions for details. The secondary containmentcollar 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 continuouslymonitored with an electronic sensor for potential spills or piping leaks.

Secondary Containment FittingA 6" FRP threaded secondary coupling is concentrically positionedaround the 4" NPT primary tank fitting. The secondary containmentcoupling is surface-mounted onto the tank and does not penetrate theouter wall. There is no access to the tank annular space at the 6"secondary containment coupling. To directly monitor the cavitybetween the primary and secondary pipe, a fitting with an access portshould be installed.

Turbine Enclosures

Fiberglass Turbine Enclosures provide access to critical equipment andserve as a termination point for piping.

Our turbine enclosures are fiberglass – a proven material for long-term performance. Compared to otherunreinforced plastics and HDPE products, the rigid fiberglass construction minimizes deformation duringbackfilling to help assure liquid-tight seals at fitting penetrations.

Turbine enclosures must be mounted on top of a secondary containment collar. Primary piping is installedfrom the submersible pump to the dispenser. When the double-wall piping is installed over the primary piping,the double-wall pipe connects to the turbine enclosure using optional fittings, available from CSI or yourpetroleum equipment distributor. In the event of an accidental spill from the primary piping, the spilled productwill drain into the turbine enclosure and accumulate in the secondary containment collar. The secondarycontainment collar serves as a basin to allow early detection of leaks of the submersible pump or the productpiping.

When there is concern about the ingress of water at the collar/turbine enclosure seam, the turbine enclosureshould be sealed to the secondary containment collar at the jobsite. Containment Solutions provides analcohol compatible adhesive kit to make this connection. Continuous electronic monitoring of the secondarycontainment collar should be used to warn the operator of the accumulation of petroleum product before theliquid level rises above the collar/turbine enclosure seam.

Turbine enclosures are available in 42" and 48" diameters with a minimum 2' length. To accommodate deeperburial depths, longer turbine enclosures are available in 1' increments. The turbine enclosure can be trimmedat the jobsite to adjust for the final burial depth.

Note: For high groundwater conditions at or above subgrade, a sealable or watertight turbine enclosure shouldbe used to prevent water infiltration.

Warning: When a tank will be equipped with more than one turbine enclosureor manway riser, the tank may require special installation (deeper burial,additional anchor straps, etc.). Contact Tank Technical Support for specificinstallation details. Warning: a turbine enclosure constitutes a confined space.Never enter a turbine enclosure without proper training and OSHA-approvedequipment.

Turbine Enclosures

Turbine EnclosuresTurbine enclosures are available in three models - Non-Sealed (NTE), Watertight (WTE), and Sealed (STE). Forall models, the turbine enclosure body is mounted on the tank collar. If a leakproof joint is required, cementthe enclosure body to the tank collar using the adhesive (Kit AD). (It is recommended that the joint always becemented.) All turbine enclosures are supplied with adhesive kits.

A minimum 36" diameter street box is required with all FRP models to allow the removal of the FRP lid afterthe turbine enclosure is installed. This also allows the removal of the manway cover.

To leak test the turbine enclosure, use a standing water test. DO NOT use an air pressure test.

Non-Sealed FRP Turbine Enclosure (NTE)Friction fit lid to repel water from aboveThe Non-Sealed FRP Turbine Enclosure includes anFRP enclosure body (variable length in 12" increments,42" or 48" ID’s), an FRP reducer (42" x 30" or 48" x 30"ID’s), and a loose fit FRP lid (32.5" OD) with handle.The enclosure body is field cemented to the tank collarusing the supplied adhesive kit (Kit AD). The reducerand the lid fit over the enclosure body with a loose fit.The 30" opening allows for the removal of a 22"manway lid (28" OD).

Field-installed piping and electrical fittingsSecondary pipe fittings can be field installed using one of our optional two-piece FRP couplings.

When used for piping connections, the FRP coupling is designed to provide secondary containmentconnections only to the turbine enclosure. Do not use the FRP coupling for primary piping connections to theturbine enclosure.

FRP Coupling Kit (3" or 4")A two-piece field-installed 3" or 4" FRP coupling can be cemented in the turbineenclosure to provide a watertight seal for piping penetrations in high groundwaterenvironments.

The FRP coupling is a two-piece fitting which is cemented to the turbineenclosure. The FRP coupling’s male and female sections are threaded together tohold the fitting in place while the adhesive cures. Each kit (Kit FC-3 or FC-4)includes the adhesive and mixing instructions.

Flexible Entry Boot (FEB)Flexible entry boots are rubber compression type boots installed into the wall ofthe turbine enclosure to seal all pipe and conduit entries. These boots aredesigned to permit up to a 300° angle of flexibility for entries. This flexibility isimportant for aligning pipe connections or as a stress relief for the pipe duringbackfilling and ground movement. The flexible entry boot is available for standard3" and 4" secondary piping and 3/4" conduit lines.

Tank LaddersOur optional tank ladders are available in either carbon steel,aluminum or stainless steel. These ladders are shipped along withthe tank and are field attached to the tank bottom with FRPmounting lugs. Ladders are retained at the top with FRP slip lugson the trunk of the manway to allow for vertical movement of theladder. (Manway and ladder are sold separately.)

Tank ladders are not recommended on 4' diameter tank capacities.Because of limited space, the ladders interfere with tank entry.

Probe DrawstringOn tanks with a dry annular space, we provide a factory-installed“drawstring” at the annular space monitoring fitting to assist in positioning liquid sensors at the bottom of theannular space.

Anchoring Systems

Deadmen/TurnbucklesContainment Solutions can provide deadmen anchors and turnbucklesfor selected models of double-wall tanks. Deadmen anchors provide ameans to prevent installed fiberglass tanks from floating out of theground when the tank installation is subject to groundwater around thetank. Deadmen anchors, when used with CSI fiberglass hold down strapsand other CSI or contractor supplied hardware and installed according toCSI installation instructions, prevent tank flotation and cost less than aconcrete pad under the tank.

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 andwithout eyebolts. Ask for “Deadmen Anchors and Turnbuckles”publication to select the proper deadmen for a particular tank size.

Split-Strap Anchor SystemContainment Solutions can provide a split-strap anchor system for 6',8' and 10' diameter double-wall tanks. The split-strap anchor systemprovides a method to attach and tighten the tank anchor straps todeadmen or to an anchor pad without entry into the excavation. Thesplit-strap anchor system is safer and less costly than traditionalmethods that require shoring or other hole stabilization techniques toallow entry into the excavation.

Fiberglass Anchoring StrapsWhen mechanical anchoring is specified, fiberglass anchoringstraps are available for all double-wall tanks.

WARNING: An underground tank constitutes a confined space.Never enter a tank without proper training and OSHA-approvedequipment.

NOTE: The use of manways is not intended to encourage tank entry,which can pose a safety hazard for unqualified mechanics,especially after product has been stored in the tank.

All fiberglass double-wall tanks include one manway. Some of the primary tank fittings are clustered in themanway cover to facilitate secondary containment of the pump and piping.

Stainless Steel Bolt RingsContainment Solutions can provide a stainless steel bolt ring for use with fiberglassmanways and sealed turbine enclosures on double-wall tanks. The bolt ring ismanufactured in two halves and provides a flexible semi-circle of bolts that will stay inposition in a flange and allow the nuts to be tightened without the use of a wrench tokeep the bolt from turning.

The bolt ring is manufactured of 304 or 316 stainless steel with non-galling siliconebronze nuts, providing improved corrosion resistance over plated bolts, nuts andwashers.
