All about bolted storage tanks

Bolted Steel tanks have a history of nearly centuries back, from the 1800s, these tanks were used in storing materials and have ever since been evolved through its precursor days. They are used to store any sort of liquids or solids which include waste water, food produce and grains. They are present in the municipal corporations, rural level, commercial and residential spaces depending on their varied sizes ranging from 60,000 to a million tones capacity.

They are also known by the name of atmospheric storage tanks which are used in place of welded tanks. Welded tanks are relatively new, however, bolded tanks are tried and tested for years on end and they are highly suggested in most industries as a safe storage option structure.

Bolted Tanks: Varied Industries

These tanks are seen in various industries and plants where heavy storage is required of goods which can be contained in large quantity.

Water Industry:

Water is the source of life and is used in practically all viable industries. Bolded tanks are used to contain drinking water in housing societies, portable water from lakes and rivers, village dam storage, municipality institutions towards city water services, private and clinical usage of healthcare divisions on rooftops, fire ambulance systems, pest control units, wastewater management, disinfection treatment plant sites and water purification spots throughout the city.

Food Industry:

Manufacturing units of large collegemates like TATA, UNILEVER and small-scale businesses as well. These provide for storage of salt companies, flour and rice brains, sugar and spice brands. All these come under the dry precooked materials. However, bolded tanks are used to keep intact perishable products like fish, meat, corn grains, milk, scratch solids, and even cocoa beans.

Mineral Industry:

Minerals like Gypsum, potassium, coal, iron ore, silica, phosphate, cure oil and mineral oil are also stored in bolded tanks.

Chemical Industry:

Construction materials like concrete, glass, bio chemicals, bio fuels, carbon black, cement, nitrate, carbonate and methanol too.

Storage of Bio-Fuels: Caustics, Glycerin, Syrup, Bulk Bio-Diesel, Methanol, Yeast Tank, Raw ingredients and bio degradable waste storage units.

Types of Bolted Tanks

Low-Capacity Bolted Tanks – Tanks that are in circumference of 29 feet size bottom width and 85/8 inches in length.

1 BBL = 40 gallons of Oil

So, capacity bolted tanks that are of:

LOW: 100 BBL, 200 BBL, 250 BBL,500 BBL

HIGH: 750 BBL, 1000 BBL and 1500 BBL

The above capacity bolted tanks are self-supporting.

Medium Capacity Bolted Tanks – Tanks that have a diameter circumference of 29 feet size and 85/8 inches in length.

1 BBL = 40 gallons of Oil

So, capacity bolted tanks that are of:

LOW: 1000 BBL, 2000 BBL and 3000 BBL

The above capacity bolted tanks are fitted with strong tall center poll like structure including a rafter support ring.

High-capacity Bolted Tanks –

1 BBL = 40 gallons of Oil

So, capacity bolted tanks that are of:

HIGH: 5000 BBL and 10,000 BBL

The above high-capacity bolted tanks are bigger than 29 feet and 85/8 inches. Also, inbuilt with a center support pole.

Features of Bolted Storage Tanks

Production Precision

API specifications have various guidelines like cutting, blending, rolling and using superior materials in coating the surface of the internal and external tanks which can then be further bolted throughout the slides and surface.

Easy Installation

The erection of bolted tanks is on the spot and flexible. Unlike a regular storage tank that requires mixing, welding and coaxing of supervisors at every stage. The bolted coating is easily sprayed over the tank which gives it a shine and this can not only be useful as a storage element but also a good-looking piece in the workplace. This tank is basically a ready to assemble structure which makes the period of installing very quick and easy.

Cranes and lifters will have to be on standby to move and shift parts during the process of steady installation.

Durable Coating

The powder coating level of durability is known to be the best used for bolted tanks. This can be done on the tank pre-transport rather than on the job site itself.

The painting and coating for other types of tanks like welded tanks require a mandatory paint job until the erection is completed. Depending on zinc-coated or hot-dip galvanized bolted tanks can be manually done or mechanically manufactured based on company instructions and needs.

Low and Easy Maintenance

These bolted tanks can get damaged as they are not pre produced and rather built on the spot. Corrosion due to rainfall and water leaks is a serious threat to tank storage which is an easy fix to maintain by unbolting and troubleshooting the problem on site. Bolted Tanks can sometimes due to substandard material used during construction gather cracks resulting in leaks. However, these minor issues are easily rectifiable.
