7 Reasons to Choose Bolted Steel Tanks for Your Storage Needs

[Posted on July 27, 2016 by Gulf Coast Tanks & Construction]

Storage tanks play a vital role in many types of businesses and organizations including manufacturing and processing plants, agricultural or ranch operations, fire protection services, water treatment facilities and municipal water distribution systems. They can be used to store many types of liquids or dry goods, including potable or non-potable water, wastewater, food products, drilling mud, sand and other materials. To be cost-effective and reliable, they must be able to be manufactured and installed quickly and easily and be durable enough to last for years without leaks or frequent maintenance.


Both concrete and welded steel tanks are durable and reliable storage options, but they are expensive, difficult to install and hard to maintain. Another option is bolted steel tanks, which are manufactured in sections at a controlled facility, then shipped to your location and assembled on site, quickly and efficiently. They offer the strength of welded steel tanks, with greater flexibility and simple maintenance.



Here are a few of the best reasons to choose bolted steel tanks for your organization’s storage needs:



#1 They Are Available in Many Sizes

Bolted steel tanks can be manufactured in a wide variety of capacities, ranging from a few thousand gallons to over a million. They can be custom designed to fit your particular application, with varying widths, heights and other characteristics. In areas where space is limited, the tanks can be made tall and narrow for a smaller footprint, or they can be made wider where vertical space is constrained. The design options are practically limitless and can allow for great flexibility in demanding applications.

#2 They Are Extremely Durable

Bolted steel tanks are made from individual sections that are formed, welded and finished at a controlled manufacturing facility, using high-quality carbon, galvanized or stainless steel that meets applicable ASTM and API requirements. Carbon steel sections receive a durable epoxy powder-coat finish that inhibits corrosion, resists electrochemical reactions and provides better coverage than the field-applied finishes common on welded steel tanks. Each section is bolted together in the filed using the appropriate gasket material for the tank contents, such as EDPM rubber or Buna-N gaskets, along with fasteners made from carbon, galvanized or stainless steel. For extra protection from contamination, leaks or corrosion, the fasteners can be capped or fully encapsulated with poly-based materials, or installed using neoprene washers. These features result in a tank that is extremely durable, with a long life cycle and minimal maintenance.

#3 They Are Easy to Maintain and Repair

Concrete and field-welded steel tanks require frequent maintenance and can be difficult to repair if they become damaged, requiring special equipment and personnel with the appropriate welding or concrete experience. Bolted steel tanks require minimal maintenance, because of their durable finish and reliable gaskets and hardware. Because they are made from individual sections, repairs are relatively easy. If a section begins leaking, hardware deteriorates, a gasket fails or an accessory malfunctions, the affected section can be disassembled and replaced, without cutting, welding or labor-intensive concrete work. This minimizes labor and maintenance costs, and leads to a storage solution with a far longer life cycle.

#4 They Are Quick to Install

With concrete or welded steel tanks, much of the manufacturing and instillation process happens on-site, requiring large amounts of skilled labor and plenty of time. In addition, because of the nature of the process, the installations of concrete and welded tanks are often subject to delays during inclement weather, increasing downtime and potential costs. With bolted steel tanks, much of the manufacturing is done off-site. Once the components arrive at the installation site, the assembly process is quick and efficient, requiring a minimal amount of time and fewer labor costs. The process can be completed in nearly any type of weather, reducing delays, and it allows the tank to be used almost immediately after completion, minimizing downtime. With proper preparation, bolted steel tanks can be installed in a matter of days.

#5 They Are Cost-Effective

Over their complete life cycles, concrete and field-welded steel tanks can be expensive to install, maintain and repair. Bolted steel tanks can offer significant cost savings for many applications, because they are quick to install, require minimal maintenance and are easy to repair. They often have a longer life cycle than competing designs, and they require fewer labor expenditures for maintenance and repairs. They area cost-effective storage solution for many types of businesses, and offer a quick return on investment.

#6 Capacity Can Be Easily Expanded

With concrete or welded steel tanks, if your capacity needs increase, often the only cost-effective option is to add additional tanks. Expanding or replacing the current tanks may be not be feasible or may require too much labor. With bolted steel tanks, new tanks can be added with minimal time and effort, thanks to the quick installation process. In many cases, it is also possible to expand the existing tanks, simply by adding additional sections. This minimizes the extra costs involved for labor and materials, and reduces the amount of space required and the downtime associated with the project.

#7 They are Extremely Flexible

Bolted steel tanks can be sued to store many types of materials, such as clean water for drinking, manufacturing, fire protection or agricultural purposes, as well as wastewater for treatment purposes. They can store food products, including liquids like orange juice or milk, as well as dry goods like grains or animal feed. In the oil industry they can store drilling fluids or sand, and for the concrete industry they can store sand, cement or aggregate for easy dispersal. The can be made in just about any size, and can be custom-designed for your application, with the appropriate gaskets, fasteners, fittings and other components for the materials that will be stored.

Bolted steel tanks offer many other advantages over conventional tank designs, including concrete, field-welded steel and composite tanks. With their long life cycle and easy maintenance and repairs, they are a worry-free long-term storage solution for just about any business or application, large or small.
