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 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.

Commercial sodium hypochlorite is the product of chlorine and sodium hydroxide. It is typically supplied as a liquid solution with a concentration of about 12%. Although the liquid solution is more expensive than gas, it has a lower health risk, it’s easier and safer to use, and it reduces the risk of releasing chlorine gas — especially in areas that are close to surrounding properties.

PolyGard™ is a seamless, corrosive-resistant polyethylene lining system for steel tanks and vessels. It’s used as a barrier to protect the steel from the aggressive chemicals you’re storing—even in the harshest of conditions. PolyGard lets you combine the chemical resistance of polyethylene with the durability and strength of stainless steel. To truly understand how effective PolyGard is, let’s examine what it is comprised of, how it is made, and how it is commonly used.

One of the most important design considerations of any chemical storage tank system is the use of flexible connectors and isolation valves. When paired correctly, these accessories will not only help ensure your storage tank’s longevity, they can also protect the tank from hinge points that cause dangerous leaks.

When you’re filling your chemical storage tank, it is important to ensure the safety of employees and equipment and to prevent loss of product. A fill line helps prevent spills while making it easy and efficient to fill the tank.

When it comes to choosing a chemical storage solution, you won’t find a more aesthetic option than stainless steel tanks. Steel tanks are popular in breweries and other applications where they’re on public display. The tanks look shiny and clean, and they contribute to the interior design of the space. Steel tanks also have a reputation for being one of the most reliable chemical storage systems on the market.

If you want your polyethylene chemical storage tank to last for its full lifetime, you’ll need to make sure your tank has the right specific gravity rating. Every chemical has its own specific gravity, and it’s critically important that your tank is designed to meet the demands of the particular chemical you’re storing. Tanks that are rated too low can suffer from mechanical stress and early failure.

Cross-linked polyethylene tanks withstand greater pressure, in part because of the rotational molding manufacturing process. Rotational molding is by far the best process to create a cross-linked polyethylene chemical storage tank.

With some chemicals, it’s critical to keep them cool because they will lose their concentration when they heat up. Sodium Hypochlorite is a prime example of that. As it heats up, it starts to lose its strength, and it begins to release gas and free radicals. Its strength can diminish dramatically with heat and UV. So it’s important to keep the chemical as cool as possible from the moment it arrives at your facility. Other chemicals are similar—if they become too warm, they won’t perform as well as you need them to.
