ATECOALUMINUM

DOMEROOF

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 a 1.2 mm thick aluminum sheeting

ALUMINUM DOME ROOF

All bolted structure and no welding is required at site 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 tank can 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 necessary assembly 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

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

The Astrodome in Houston is 200 meters diameter.

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 component parts pass through a standard tank shell manhole

• no welding at site - complete installation can normally 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 the vapour 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 an upgrade to the very successful ATECO Ultimate Internal Floating Roof can accommodate storage tanks with a high frequency of filling and discharge of product.

Designed to withstand loads up to 1000 lbs/sq. ft. Installation all ATECO pontoon

type of internal floating roofs is quick and efficient as it is sent to site completely prefabricated, no welding 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.

Cable-Supported Internal Floating Roof

ATECO internal floating roofs can be suspended from cone roof tanks or aluminum dome roofs:-

Primaryand

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 since this is always present this type of seal has proved 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 intent of API 650 and NFPA 10 however, to fully comply with NFPA 10 we also offer 3.5 mm 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 three hardened staınless steel plates provıdıng sıx pressure poınts on each 1.6 mm thıck shoe plate.

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

The Ateco Pusher Plate Prımary Seal ıs compatıble wıth most stored products and wıll maıntaın a very tıght seal 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 the workıng tolerances of the rım gap are exceeded.
