The Ateco Aluminium Geodesic Dome Roof is an all bolted structure and no welding is required at site for its assembly and erection. It fully complies with the requirements of API 650 Appendix G. Being a self-supporting structure internal roof column supports are not required. The aluminium dome roof is now the design of choice for most tank operators and is frequently to be found on oil and refined storage tanks as well as potable and waste water tanks. Because of the corrosion resistance of aluminium alloys the Aluminium Dome Roof does not require painting – EVER, and can therefore be considered as maintenance free in this respect.
Ateco offer various designs of internal floating roofs - pontoon and full contact 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 pontoon internal floating roof is without doubt the most cost effective type due to ease of assembly and installation and with various designs to choose from we have an internal floating roof to suit most operational requirements.
API 650 advises that all tanks storing hydrocarbon liquids should be fitted with a seal system comprising a primary seal and a secondary seal. Ateco manufacture a range of primary and secondary seals designed for a rim gap of 200 mm to 250 mm +/- 100 mm, however most can be modified to accommodate varying gaps. The most popular seals are mechanical seals and this simply means that most of the seal parts are made from metal, however we also supply foam and liquid filled seals. Most mechanical primary seals can if necessary be fitted with a wax scrapper and drip curtain.
Ateco offer two types of roof drain systems for external floating roof tanks – articulated pipe with BendMaster and articulated pipe with swivel joints. The articulated pipe with BendMaster is the most practical and cost effective roof drain system incorporating the maintenance free BendMaster. The articulated pipe with swivel joints is another practical and cost effective roof drain system incorporating dependable and long lasting swivel joints which are custom built to ensure they are compatible with most stored products.
Floating Suction Units are primarily used to draw off product from just below the surface of liquids stored in fixed roof tanks to avoid transferring contaminants to the pumps and process equipment. We manufacture a range and size of swing joints including double and single arm with component parts compatible with most stored products and in diameters from 75 mm (3 ins) up to 1000 mm (36 ins).
The Ateco Guide Pole Sleeve, Leg Seals and Leg Socks are designed to control the vapour emissions coming from the slotted guide/gauge pole and the roof support legs on an external floating roof tank. Made from high quality urethane laminated fabric compatible with most hydrocarbon products these cost effective measures are an essential addition on a tank to obtain the maximum control of vapour emissions.
The Ateco Rewinder Earthing System for external floating roof tanks is an effective and virtually maintenance free electrical grounding system specifically designed for subduing sustained arcs during lightning storms. The unit is bolted to the highest point of the tank and the tinned copper braided cable is bolted to a point on the floating roof - it extends and retracts as the floating roof travels up and down.
Ateco design and supply a completely integrated fire detection and suppression rim seal protection system as well bladder tanks, the essential component equipment in a balanced pressurized foam proportioning system, for external floating roof tanks to meet the requirements of NFPA 11.
AKTEK an Ateco Group Company design and manufacture a complete range of equipment for storage tanks, including:- Pressure Vacuum Vent - Gauge Hatch - Emergency Vent - Rim Vent - Manhole Cover - Flame Arresters.
Ateco has qualified and experience engineers who can support the installation of all Ateco tank equipment on site, we also offer inspection services to give advice on the operation, maintenance, repair or replacement of all Ateco supplied tank equipment.
