Types of Storage Tanks
Industrial chemicals are notoriously hazardous, necessitating tanks made from sturdy materials for the safe storage of both raw materials and finished products. These tanks serve an integral function during production by mixing natural ingredients before being used to store finished items. Find out the best info about storage terminals.
Small bolted tanks are well suited to remote production fields, while larger welded storage tanks may be employed at refineries and distribution terminals. API Spec. 12D Field Welded Tanks for Storage of Production Liquids provide standard designs for these tanks.
Bolted Steel Tanks
Bolted steel tanks offer an ideal industrial, commercial, and residential solution. Their capacity ranges from hundreds to millions of gallons and can accommodate almost any liquid imaginable. Bolted steel tanks offer an alternative to concrete as they can easily be customized according to project specifications such as AWWA, NFPA, and API standards.
These tanks are constructed using carbon or galvanized steel sections formed, welded, and finished in a controlled manufacturing facility, making assembly quicker and repairs more straightforward when necessary.
Bolted tanks offer more durability than concrete or welded steel storage tanks due to their factory-applied coating and corrosion-resistant interior liner, plus they’re easy to expand should more storage capacity become necessary in the future.
Polyethylene tanks are ideal for chemical-based liquid products as they are durable and corrosion-resistant. Furthermore, production costs for polyethylene tanks are much less than for stainless steel ones, and these models also boast superior leak resistance due to being seamless units without seams or seam seals.
Plastic tanks may not be as durable as concrete ones, and owners must take caution when placing heavy objects atop them. Too much weight could dent or warp the plastic surface, so they are typically only used for aboveground storage purposes.
UV radiation can weaken polyethylene tanks, so their structural integrity may diminish. Cracked areas in the tank’s shell may appear similar to dry rot or alligator skin – usually visible only with a close examination of the skin itself.
Corrugated Steel Tanks
Corrugated steel tanks are often used for rainwater storage, making great biosolids and sludge storage solutions. Their superior compressive load resistance makes them popular among businesses needing bio-solids or sludge management systems.
These tanks provide a cost-effective, hassle-free alternative to concrete water storage tanks and can be assembled easily. Their features include extended manways and thief hatches for added safety, plus they don’t leach calcium into the water supply and boast more sanitary interior conditions than concrete tanks.
These tanks can be field installed onto a gravel foundation without anchors to meet seismic safety standards without incurring extra costs of installing concrete foundations, making them easy to transport between locations or for permanent use.
Pillow tanks are versatile water storage solutions designed to hold drinking water, brine water, frac fluids, and mineral mining water. When empty, they lay flat before rising to form a pillow shape when filled. Pillow tanks are perfect for locations requiring quick set-up times at reduced shipping costs and tight spaces where easy movement may be needed.
These bladder tanks are safe, durable, and designed to withstand harsh environmental conditions. Unlike standard tank designs, bladder tanks feature high-grade elastomer-coated fabrics for added strength against tears or punctures; furthermore, these tanks feature easy refueling nozzles.
Folding tanks are collapsible water tanks designed for emergencies and locations with limited space. They are easily transported between locations via fire truck, helicopter, or water bowser – known as collar tanks- these water containers can be set up within minutes and used for everything from fire fighting, disaster relief, and military operations to oil spill containment.
Flexible tanks (also referred to as flexitanks, loose, and flexitank systems) are constructed from high-tensile polyethylene that has been blown and cross-linked for maximum flexibility and minimal weight. Rustproof, foldable, and quick to set up quickly, these lightweight solutions offer many advantages over steel tanks with similar capacities; they are lower in weight than their steel counterparts. However, flexible tanks should only store gases and common pressure chemicals; liquid storage requires pressure tanks.
