3 Fuel Integrity Issues to Confirm With Storage Tank Manufacturers

Once these agents compromise the integrity of your stored fuel, the equipment that will use the fuel may develop mechanical problems. That may further cause you to incur more costs in repairing the machine, or in a lawsuit that your customers may file against you for offering them poor quality fuel.

Here are some of the problems you need to watch out for:

Particles in Stored Fuel

Always confirm with your storage tank manufacturer if they install well-fitting filters at the inlet of every storage tank to filter out small particles and other contaminants. Avoid using galvanised tanks to store fuel for long periods because the fuel may react with the zinc alloys and form particles that contaminate the stored fuel.

Water in Stored Fuel

Water can further compromise the quality of fuel in storage tanks. You should ensure that the storage tanks you order come with desiccant breathers. With this feature, you will not only keep the inside of your tank moisture-free; the desiccant breather will also get rid of airborne debris.

Microbes in Stored Fuel

Microbial activity typically thrives best under slightly high temperatures, even up to a 100° Celsius. But it would be more costly and dangerous to maintain fuel temperatures above that. The safest alternative would be to ensure that the tanks have enough padding to insulate them from extreme temperatures and minimise condensation to reduce microbial growth.

Turning the Tanks

You also can have a storage tank that you can turn the fuel inside to minimise moisture and microbe problems. But such tank sizes will largely depend on the contingency requirements and the particular applications of the storage tanks.

Make sure your storage tank manufacturer consider and provide solutions to these problems when producing your tanks. This way, you can be sure that you will have near zero issues of microbes, particles and water in your stored fuel.

Preparing for Precipitation: How Weather Resistant is Your Steel Storage Tank?

Storage TanksThe weather in Oklahoma is finally getting a bit cooler and wetter. Some much needed rain is a blessing after a long streak of unusually warm weather brought about by El Niño.

We aren’t out of the woods yet, though. Although the weather forecast is slightly better, the heat will still be consistently high until it reaches its peak in summer.

If you have a steel storage tank, the rains may be really good news — especially if the tank’s purpose is to collect rainwater for personal and industrial use. However, it’s still important to “rain-proof” your steel storage tanks. A combination of heat and precipitation isn’t exactly good for your container.

Heat and Rain

While rain is a welcome event as it washes away atmospheric pollutants that have settled on the exposed surface of steel, it’s also instrumental in accelerating corrosion.

Steel is normally strong and more weather resistant than weaker metals like iron, but dew and water can easily collect in small pockets and crevices. In the steel storage tank’s case, the precipitation can intrude into surface aberrations and imperfections. This eventually causes corrosion and rusting, which compromises the strength and weather proofing ability of steel.

Cycling temperatures also contribute to steel surface corrosion. Repeated shifts from humid and rainy weather to dry and extremely hot can severely affect the overall durability of steel. In steel storage tanks, the repeated shift from hot to wet can also destroy both the internal and external PVC liner.

Weather Proofing the Tank

The current forecast for Oklahoma’s weather is still relatively unreliable. Although there are frequent bouts of rain, a hot spring season is still what many expect. For a person with several above ground steel storage tanks, it’s important to weather proof both for the rain and for the heat.

Rain or heat proofing your steel storage tanks doesn’t take much. Just make sure the steel storage tank’s coating is still relatively “intact.”

Your main concern will be the external coating. The kind of internal PVC coating necessary depends on the kind of product or material you’re storing. The external coating ultimately depends on what kind of environmental and weather conditions your area experiences.

If your area experiences more rain, apply coating that completely protects it from the rain. The same is true if your area experiences drier and hotter weather conditions. Also consider temperature variance and snowfall.

It’s also crucial to inspect for any signs of damage or weathering. It may be a hassle to address now, but that small hole or leak in the storage tank may become a more expensive repair venture in the future.

Weatherproofing your steel storage tank doesn’t just involve making sure it has the right external coating; it also means checking for surface aberrations and signs of damage. With the unusual weather, weatherproofing is more of an investment than a simple aesthetic touchup.
