Storage tanks,Fixed-roof tanks,Floating roof tanks

Fixed-Roof Tank.Of currently used tank designs,the fixed-roof tank is the least expensive to construct and is generally considered the minimum acceptable equipment for storing liquids.A typical fixed-roof tank consists of a cylindrical steel shell with a cone- or dome-shaped roof that is permanently affixed to the tankSteel Water-Storage TanksBolted tanks are currently offered in incremental sizes depending on the tank manu-facturers panel size.Capacities offered range from 4,000 gal (15,000 L) to approxi-mately 2.5 mil gal (6.8 ML).Bolted tanks are available in reservoir and standpipe configurations.Maximum tank heights and capacities are limited by the manufactur -Steel Tank FeaturesTanks are supplied ready for erection,complete with external ladders,walkways,roof and shell manholes and various other fittings as required.Heating and cooling coils can also be provided.Capacities range from 2,000 litres to 190,000 litres.Larger capacities are available on request.VERTICAL STEEL TANK FEATURES A broad range of uses:
