ALUMINUM

DOME

ROOF

Aluminum alloy is one of the world’s most commonly used metals.

Lightness - Strength - Excellent Corrosion Resistance

The ATECO aluminum dome roof is a system of:-

• triangular lightweight extruded profiles• connected through node points• transmitting all the roof loads laterally to the

integral tension ring• then through sliding or fixed supports to the

tank shell and the tank foundation.

The framework is covered with a1.2 mm thick aluminum sheeting

ALUMINUM DOME ROOF

All bolted structure and no welding is required atsite for its assembly and erection

Complies with the requirements of API 650 App.G.

The standard ATECO aluminum dome roof is fitted with

Sliding Supports and an Integral Tension Ring. This

reduces the forces being transmitted to the tank shell

and generally means that there is no significant

modification required to the tank.

Totally supported on the tank shell without any need for internal supports .

Aluminum dome roof do not require painting – EVER

Maintenance free for the entire lifetime of the tank.

Ateco offer the following features

in our standard design:

• Integral Tension Ring

• Sliding Supports

• Free Vent

Any equipment that you have on a conventional steel dome or cone roof tankcan be fitted on the ATECO aluminium dome roof and without any significant modification to the equipment or the roof.

The ATECO dome roof ratio

(dome height : tank diameter) is about1:6.

ATECO aluminum dome roof can be designed to

support a suspended aluminum internal floating roof.

Design Features of the ATECO Aluminum Dome Roof

ATECO can supply all the necessaryassembly and erection equipment

Assembly inside or outside the tank - lifted using

either a system of pulley blocks or a crane

If using the “jacking method” to erect the

tank, the Dome Roof is fitted on the top course

and jacked up with the shell Dome assembly on top of a floating roof

Erection of the ATECO Aluminum Dome Roof

• ATECO aluminium dome roof is a self-supporting

structure

• ATECO aluminium dome roof lightweight

construction means that when fitting on an existing

external floating roof tank it is not normally

necessary to reinforce the tank shell

• ATECO aluminium dome roof is fitted with an

Integral Tension Ring to avoid any additional

stiffening requirement of the tank shell

• ATECO aluminium dome roof does not require

painting, EVER - in this respect it can be

considered as maintenance free for the entire

lifetime of the tank

Main advantages of the ATECO Aluminum Dome Roof

• Bolted construction makes site assembly

quick and easy

• completely prefabricated panels

incorporating factory applied surface

protection

ATECO supply an aluminum and galvanızed steel formed flat panel roof for bolted tanks in

accordance with AWWA and API 12B

• Pivot hinged connection to the tank

shell

• light weight

• does not require internal supports

• desıgned for a combıned Dead Load

and Snow Load of 85kgs per sq. meter.

Dome and Flat Roofs for Bolted Panel Tanks

For smaller diameter tanks

they are generally more

competitive than a steel

welded tank

Geodesic – means the shortest line between two points

on a curved surface.

Mr Buckminister Fuller from USA developed the

principal of the geodesic dome in the 1940’s

primarily for social housing .

The aluminum dome roof used on tanks is not strictly

geodesic - the main profile beams are connected

at node points on the surface of a sphere.

INTERNAL

FLOATING

ROOF

ATECO offer as standard a simple double

polyethylene foam seal on all internal floating roofs

• ease of assembly and installation - all componentparts pass through a standard tank shell manhole

• no welding at site - complete installation cannormally be carried out in a matter of weeks

• can accommodate both primary mechanical shoe

seal and a secondary seal

Internal Floating Roofs are installed in Fixed Roof Tanks to control thevapour emissions from volatile hydrocarbon liquids.

The pontoon type has the most cost effect features:-

ATECO offer pontoon and full contact types, that meet and in most cases

exceed the requirements of API 650 Appendix H.

Although there is a fundamental difference in the design of each type of roof, many of their features and accessories are the same.

Selection is primarily based upon the preference of the owner.

The Ateco Robust Pontoon Aluminum

Internal Floating Roof has 254 mm (10

ins) dia. X 2.5 mm thick extruded

aluminum alloy pontoons - 0.5 mm

thick aluminum sheet. Designed to

withstand loads up to 500 lbs/sq.ft.

The Ateco Ultimate Pontoon

Aluminum Internal Floating Roof has

200 mm (8ins) dia. X 2 mm thick

extruded aluminium alloy pontoons

- 0.5 mm thick aluminium sheet.

Designed to withstand loads up to

500 lbs/sq. ft

The pontoons are an integral

component of the basic structure

The pontoons are suspended

from the basic structure

The Ateco Ultra 2000 Internal Floating Roof is anupgrade to the very successful ATECO UltimateInternal Floating Roof can accommodatestorage tanks with a high frequency of fillingand discharge of product.

Designed to withstand loads up to 1000 lbs/sq. ft.

Installation all ATECO pontoon type of internal floating roofs is quick andefficient as it is sent to sitecompletely prefabricated, nowelding is required to complete the assembly and all component parts fit through a standard tank 24 ins shell manway.

ATECO offer the following design of full contact internal floating roof: -

ATECO OpenDeck - Pan Type

The ATECO OpenDeck Internal Floating Roof features include:-

manufactured in either aluminum or stainless steel

product vapors or liquid cannot leak ınto or be trapped in buoyancy chambers

completely prefabricated panels are bolted together at site

A very efficient and cost effective IFR compatible with most stored products.

allows roof height adjustments to be

completed from the outside the tank

no leg structure under the roof - cleaning

inspection and repairs to the tank bottom are

simplified

more efficient in the control of vapour

emissions as the roof does not have the

penetrations in the deck sheets to

accommodate the roof legs.

ATECO internal floating roofs can be suspended from

cone roof tanks or aluminum dome roofs:-

Primary

and Secondary

Seals

for

External

Floating Roof

Tanks

. The ATECO Weighted Pantograph Primary

Seal comprises 1.6 mm galvanised or

stainless steel shoe plates which are held

against the tank shell by a system of levers

and heavy weights.

A vapour barrier is then fastened between

the top of the shoe plates and the top of

pontoon on the floating roof

The pushing force is gravity and sincethis is always present this type of seal hasproved to me robust and very reliable.

However, installation, maintenance and repair is relatively difficult and for this reason ATECO has introduced the ATECO Pusher Plate Primary Seal which is commonly referred to as a “top mounted seal” meaning that this seal can be initially installed and subsequently accessed for maintenance and repair from the top of the floating roof.

The Ateco Pusher Plate Primary Seal comprises 1.6 mm

galvanised or stainless steel shoe plates which are

held against the tank shell by hardened staınless steel

spring steel plates.

Installation, maintenance and repair is

relatively straight forward since all parts of the

seal can be access from the top of the floating

roof and even with the tank in service.

The Ateco Double Compression Plate Seal is a very efficient

and most cost effective seal system since it comprises a primary and

secondary seal in the same unit.

Features include 1.6 mm thick independent and overlapping galvanized or 1.2 mm stainless spring steel compression plates. A

continuous vapour barrier membrane can be included.

The ATECO Foam Log Primary Seal comprises a 2 mm thick

PVC Nitrile envelope surrounding ccompressible polyurethane foam.

The main primary seal in the non mechanical category is the Foam Log Seal

The more “pressure points” that are applied to the shoes plates the

more efficient the seal – the ATECO Weighted Pantograph Seal and the

ATECO Pusher Plate Seal have six (6 No) pressure points per plate.

ATECO supply a foam dam that bolts on the pontoon rim angle and has the same hole spacing as the primary and secondary seals, With either 1.6 mm Galvanized or 1.2 mm Stainless Steel Plates the ATECO Foam Dam meets the intentof API 650 and NFPA 10 however, to fully comply with NFPA 10 we also offer 3.5mm thick plates for bolting or welding to the tank roof.

Mechanical seals can be fitted with a wax scraper and where highly volatile products are stored a drip

curtain can be attached and this has the effect of enhancing the sealing efficiency in areas where seal tip

to shell contact is less than perfect due to protruding welds or severe corrosion of shell plates.

ATECO have a range of seal tips

manufactured from composite material

compatible with most stored products

The ATECO Compression Plate Secondary Seal with 1.6 mm independent and overlapping galvanized or 1.2 mm stainless steal spring steel plates is the

most popular secondary seal and can be used with all the ATECO primary

seals. A continuous vapour barrier membrane can be supplied

A mechanical seal has lower frictıon resistance and Ateco has developed a lighter weight mechanical pusher plate type of primary seal specıfıcally for use with an aluminum internal floating roof.

The Pusher Plate Prımary Seal ıncorporates threehardened staınless steel plates provıdıng sıxpressure poınts on each 1.6 mm thıck shoe plate.

Thıs ıs a top mounted seal whıch means ıt can be ınıtıally ınstalled and subsequently maıntaınedfrom the top of the ınternal floatıng roof.

The Ateco Pusher Plate Prımary Seal ıs compatıble wıth most stored products and wıll maıntaın a very tıghtseal over a rım gap varyıng from 100 mm to 300 mm with six pressure points on each shoe plate.

We also ıncorporarte ‘faıl save’ features to prevent damage to the seal and tank ın the event that theworkıng tolerances of the rım gap are exceeded.
