Ask ten people what matters most when they buy a chemical storage tank and you'll get ten different answers. Ask us, and we'll give you one: the specific gravity of the chemical going inside. It's the number that shapes how thick your tank walls need to be, and it's one of the fastest ways to turn a storage tank into a safety problem if you get it wrong.

Liquid fertilizers have become indispensable to modern agriculture, and for good reason. They are easy to meter, blend, and apply, and they give growers precise control over the nutrients delivered to a field. But the same qualities that make liquid fertilizers so effective also make them demanding to store. They are dense, often corrosive, frequently temperature-sensitive, and unforgiving of a tank that fails.

Ask anyone what keeps a data center alive, and you'll hear the same short list: redundant power feeds, battery banks, diesel generators, and the chillers that keep rack inlet temperatures where they belong. Nobody mentions a high-density crosslinked polyethylene tank sitting on a containment pad near the cooling yard.

It is one of the most common questions we hear from customers specifying a new chemical storage system, and the honest answer is: sometimes, but far less often than most people assume.

Sodium hypochlorite is one of the most widely used chemicals in municipal and industrial water treatment, and it is also one of the most demanding chemicals to store. Facilities rely on "hypo" to disinfect drinking water and wastewater, to control biological growth in cooling systems, and to sanitize equipment across food and beverage production. It works because it is an aggressive oxidizer — and that same property is what makes it so hard on the tank system holding it.

Ten manifolded 15,500-gallon crosslinked polyethylene tanks hold the same volume as a 150,000-gallon steel tank — typically for less money, and they let you take one tank out of service without taking the plant down with it.

Hydrofluoric acid is one of the most widely used industrial chemicals in North America — and one of the most unforgiving. From semiconductor fabrication and metal processing to glass etching and water treatment, thousands of facilities rely on hydrofluoric acid every day.

Environmental stress cracking is a tiny menace that can cause great damage to your polyethylene chemical storage tanks. It often begins as a web of tiny surface-level micro cracks that are difficult to see during a routine inspection. Over time, those small cracks can grow.
