Many industries require on-site storage of either liquids or dry goods, typically in large exterior tanks that provide easy access for loading and unloading the materials. Traditionally, these storage tanks have been made out of concrete or welded steel, for larger tanks, or plastics or composites, for smaller tanks, each of which has certain strengths and weaknesses.
Another option is bolted tanks, which are made from individual steel or aluminum sections that are manufactured and finished in a controlled manufacturing facility, then transported to the site and assembled, using EPDM rubber gaskets and galvanized bolts to provide a strong, leak-free seal between adjoining sections. Because of their unique construction, bolted tanks have a longer life than competing systems, with fewer maintenance costs and easier repairs. They are stronger than plastic or composite tanks, harder to puncture, and do not suffer from UV degradation. They are lighter than traditional steel or concrete tanks, easier to install, and it costs less to transport the materials for the tank to the site. They can be customized to fit in tight locations, and as storage needs increase, the capacity of bolted tanks can be easily expanded.
Bolted tanks are used in by many industries for storing water, fuel, chemicals, dry goods and other products. Here are a few of the most common applications:
#1 Municipal Water Systems
Tanks for municipal water systems must store potable water safely and provide enough capacity for a village, town or city. Bolted tanks for potable water storage are available in sizes from 4000 gallons to over 3 million, and can be made with different materials to fit the application, including factory-coated carbon steel, galvanized steel, stainless steel or aluminum. With a variety of diameters from 9 feet to 148 feet, bolted potable water tanks can be customized to fit nearly any location, and they meet USDA, FDA and NSF Standard 61 requirements for potable water storage.
Unlike welded steel or concrete tanks, bolted tanks are quick and easy to install, allowing a municipal water supply facility to install a new tank with minimal disruption to the water system and to add more storage easily as the supply needs increase. Individual bolted tanks can also be expanded, allowing for increased storage in the same physical footprint.
#2 Well Storage Tanks
Rural and suburban wells sometimes cannot supply the instantaneous needs of a household or business, especially those in drier climates or where the water table is extremely low. In those cases, storage tanks are often used to collect water from lower-capacity wells, serving as a buffer for when water demand is higher than what the well can supply on its own. They can also function as overnight storage for remote areas that rely on solar power to drive the well pump, allowing the high-energy pumping to be done only during sunlight hours, with the tank providing storage that can be utilized with a gravity-feed system or a small low-power pump after the sun goes down.
Bolted tanks can be used to store either potable or non-potable water from wells, and are available in a variety of sizes for home or business use, starting at 4000 gallons. They offer more value to homeowners and small businesses than tanks made from competing materials, as they are more durable, require less maintenance, and can easily be expanded as storage needs increase. They are easy to repair if there are problems in the future, and they do not suffer from corrosion as much as welded steel tanks, which must be finished on-site. Bolted tanks are a cost-effective option for small installations.
#3 Fire Prevention Systems
Large storage tanks are often used at manufacturing facilities, air ports, fire stations, and remote locations to store water for fire suppression purposes. Bolted tanks work well for this purpose, as they offer plenty of capacity and they are quick and easy to install. They are compact and light compared to welded or steel storage tanks, so they can be easily transported and installed in remote locations. They can be customized with different coatings and gaskets to handle not only water, but other types of fire suppressants as well, such as foam or special chemicals.
#4 Waste Water
When water from industrial processes, manufacturing plants, municipal waste facilities or storm water management systems must be stored or treated, large storage tanks are required. Bolted tanks can be customized with a variety of coatings, gaskets and fasteners that are both chemical and corrosion-resistant, allowing for the storage and treatment of the worst kinds of waste water.
Bolted tanks can be used for processes such as aerobic or anaerobic digestion, chlorination, biological treatment, or they can store the various forms of waste water during each step in the process, such as raw sewage, dewatered sludge or even treated water. They can also be used to store the chemicals used for treatment, such as chlorine or carbon. Bolted tanks provide an efficient solution for the storage of all types of waste water, and new tanks can be easily added or existing tanks expanded to increase storage and treatment capacity.
#5 Dry Storage
Bolted tanks can also be used for the storage of dry goods and materials, such as the sand and cement used at a cement factory, dry chemicals used at a manufacturing facility, or for corn, wheat, rice and other grains stored at a farm for human or animal usage. Bolted tanks can be customized with a number of different coatings and gaskets, including food grade materials, for the storage of just about any dry product. The size, shape and capacity of the tanks can also be customized to meet the needs of the particular installation. Bolted tanks provide a cost-effective solution for the storage of just about any dry good.
Bolted tanks offer a durable, long-lasting alternative to steel or concrete tanks that are also cost-effective and easy to repair and maintain. They can be used to store just about anything, including liquids like fuel, chemicals or water, as well as dry goods, including food products, and can easily be expanded as requirements change.
