Proper tank design is crucial to successful safe chemical storage. Purchasing a chemical storage tank isn’t just about selecting the right size — it is vital to design the proper tank configuration for the safety of your employees, the protection of the environment, and to leverage your investment.

We get a lot of questions about the standard testing on chemical storage tanks that we do at our facility. Vertical tanks larger than 500 gallons in most cases are extensively tested to ensure that they meet ASTM standards. Depending on customers’ needs, we also offer additional testing on our chemical storage tank systems. Let's take a look at the types of chemical tank testing that Poly Processing performs, how we do it, and why these tests are so important in the chemical storage tank production process.

Sodium hydroxide (NaOH), also known as caustic soda or lye, is a common inorganic compound that is typically used as a strong chemical base. In liquid form, caustic soda becomes “slippery” and tends to find weak points in storage containers, and fittings, and can eventually create drips and leaks.
Environmental stress cracking occurs in plastic tanks over time, under certain conditions. It’s a failure of the polymer material due to surface-initiated micro cracks or fractures. These micro cracks are caused by the combination of stresses and environmental effects.

One of the challenges in storing any oxidizing chemical is engineering a chemical storage tank that not only contains the chemical but has a greater life expectancy and measure of safety. Whether you’re storing sodium hypochlorite, sulfuric acid, hydrochloric acid, or other oxidizing substances, it is critical to design the storage tank with the chemical in mind.

Poly Processing’s standard crosslinked polyethylene tank systems can withstand process temperatures up to 100°F — but that figure can be misleading, because there are different types of temperature to consider.

Customers often ask us how to safely dispose of a chemical storage tank once it has reached the end of its useful life. Although Poly Processing doesn’t offer tank decommissioning services, we can offer you guidance for proper chemical tank disposal.

Chemicals stored in polyethylene tanks always require venting. Depending on the chemical you’re storing, the harmful fumes emitted from the storage tank can’t be directly released into the atmosphere. To reduce the harmful fumes before they evacuate the system and to control air pollution, fume scrubbers need to be installed.

Poly Processing tanks are used for water and wastewater treatment applications, but are also found in dozens of industries nationwide. We’re able to work with a wide variety of businesses and organizations that use chemicals to produce goods and products. This is the first in a series of articles over the next several months that will feature a selection of the markets we serve. (View the full list of the markets we serve.)

When it comes to a full discharge tank, cone-bottom tanks get the job done—except when they don’t. The fact is, cone-bottom tanks fall short on several fronts. Cleaning cone-bottom polyethylene tanks can be challenging. They require additional vertical space and safety precautions. And the tanks themselves cost a pretty penny — especially when you have to include a stand and basket to support the cone-bottom tank. Prices can skyrocket in today's market with the costs of metal and special coatings. Lead times for welded steel products can be extremely long as well.
