Selecting the proper tank fitting—and location for the fitting—is an important matter. You need the right fitting for your application, and it’s not always easy to understand which one is the best choice for your needs.
Steel tanks and vessels provide exceptional strength, but they’re susceptible to chemical corrosion. Any steel tank used for storing harmful chemicals will need to be protected with some form of internal lining/liner. A polyethylene lining system is designed to protect your steel tank against the harshest chemicals to give you broad chemical resistance alongside the durability and strength of a steel tank.

How do you know by looking at a chemical storage tank how well it’s constructed? There’s a big difference between a well-designed, properly constructed tank and an inexpensive one that doesn’t meet structural requirements. But it takes more than the naked eye to spot critical flaws.

The pharmaceutical industry has a history of using stainless steel storage tanks due to the belief that the resins in a polyethylene storage tank would allow leaching and bacterial growth with pharmaceutical products. But stainless steel tanks have drawbacks. Because they can contain chemical attack points, the tanks require expensive coatings and ongoing maintenance and inspection. Seams and welding spots are especially prone to compromise.

Note: Poly Processing's seismic clip names have changed from L designation to A designation. The clip thicknesses have changed as well. Please feel free to contact customer support for any clarification you might need. One natural event that could potentially lead to catastrophic risk, resulting in a complete failure of a chemical storage tank system, is an earthquake. Earthquakes can happen in areas not considered earthquake zones, such as the August, 2011 5.8 magnitude tremor that rocked Virginia.
Aluminum sulfate, also known as cake alum or papermaker’s alum, is a flocculant chemical, much like ferric.

Sulfuric acid is one of the most commonly used acids in the world and it is used in a wide variety of industrial applications. It’s commonly used in water and wastewater treatment and in the manufacturing of chemicals, fertilizers, and car batteries. It inherently releases high amounts of heat and presents unique storage challenges. Let’s look at the some of the storage challenges and best tank solutions.

Sodium chlorite is an NSF/ANSI 61 approved chemical when using a high-density cross-linked polyethylene tank manufactured by Poly Processing. This salt-based chemical compound is an oxidizing agent that needs to be protected from contamination. If crossed accidentally with an organic material, sodium chlorite could produce an explosive reaction. With such a threat, it’s important that proper chemical storage be taken seriously.

Safely storing chemicals such as hydrochloric acid or hydrogen peroxide that emit chemical fumes requires special considerations. You must implement special methods of venting in order to reduce the harmful vapors and pressure that could endanger your employees, your equipment, or the environment. To protect these three things, Poly Processing developed a fume scrubber for potentially harmful chemical storage applications.
