Do you need a metallic storage tank that can be used to store water or other food-grade substances? Various materials can be used to fabricate a storage tank, and this is mainly determined by what you plan to store, how you use the tank and storage conditions. One of the best materials you can use is stainless steel, and with good reason.
Stainless steel is capable of resisting corrosion compared to carbon steel, and this makes it highly durable. So, even if you store the tank outdoors, it will withstand the UV rays. You won't face weathering problems that occur when using a plastic or steel tank. Stainless steel is also easy to recycle, ideal for low-temperature applications and can be easily customised to suit your fabrication requirements. Moreover, it comes in multiple grades, so you can choose the ideal fabrication material depending on the application. The maintenance costs of stainless steel over the years are also low, making it a better option.
Here are kinds of storage tanks you can instruct your stainless steel fabrication expert to make.
Fixed roof tank
A fixed roof tank is one of the less costly storage tanks you can fabricate and is ideal for storing liquids. Typically, this tank comprises of a cylinder-shaped shell with a dome- or cone-shaped roof. The roof is attached to the shell of the tank permanently. Because these tanks are completely welded, they are vapour- and liquid-tight. A breather valve is also mounted on the roof of the tank so when temperature, liquid level and barometric pressure change, the valve will prevent the release of vapour. Older tank designs, however, have riveted construction and aren't vapour tight.
Horizontal tanks are smaller storage tanks that are often constructed for both underground ad above-ground service. Their design incorporates features such as manholes and pressure-vacuum vets, including gauge hatches that make it easier to access the tank and its contents. Usually, the tank's length shouldn't be six times greater than its diameter. When you use stainless steel material to fabricate the tank you won't have to worry about corrosion. Underground horizontal tanks made with other metals that can corrode have to be protected cathodically—placing sacrificial anodes in the tanks.
If you would like to store high-pressure fluids in the tank, consider installing a spherical storage tank. Thanks to their perfectly curved shape and smaller surface area per unit volume, these tanks are stronger. The shape balances pressure distribution on the tank surface, eliminating weak points. For this reason, it costs more to fabricate a sphere storage tank.
