Chemical leaks present several major challenges for your facility. They can cause damage to storage systems, employees, and the environment. Repair and cleanup costs can be expensive, and the leaked chemical is wasted.

Twenty years ago, the availability of commercial grade cross-linked polyethylene (XLPE) for chemical storage tanks was limited to a small number of sources. The limited supply, as well as a wide variation in quality, made it challenging to find quality resin for chemical storage tanks. 

Maintaining the proper temperature of a chemical inside a high density crosslinked polyethylene tank can be critical for safe and effective storage. For example, sodium hydroxide and caustic soda need to maintain temperature to prevent crystallization at lower temperatures.

You’ve heard the adage, “if a job is worth doing, it’s worth doing right.” Poly Processing believes this to be true 110% of the time when it comes to containment. Every single piece of a tank system needs to be completely secure to protect your workspace, your employees, the environment, and the chemical being stored. 

When you install a tank-within-tank or double wall storage tank system like the SAFE-Tank with a sidewall fitting, it may be important to also install a bellows transition fitting. The bellows fitting lets you safely connect the primary tank with the secondary containment tank.

Poly Processing has three manufacturing plants in the United States. In each facility, we use a multi-step quality control process that meets and/or exceeds industry standards, including ASTM D-1998. The ASTM D-1998 standard is designed to give end users a margin of safety and peace of mind. It’s a voluntary standard, and not all tank manufacturers follow it.

With over 50 years of experience in creating tanks, fittings, accessories and other materials that ensure your chemical storage solution is safe and tailored to the chemical you are storing, we understand the importance of using the right products for your chemical. We’ve learned how the most popularly stored chemicals, like Sulfuric Acid, Sodium Hypochlorite and Hydrochloric Acid, react to improper storage systems. One part of those tank systems that is crucial is a tank’s gaskets. The tank’s gaskets act as a mechanical seal with a particular fitting to prevent leaks or spills. It is very important to make sure the gaskets and bolts used on your storage tanks are in compliance with what is needed to protect your tank fittings from corrosion caused by reactive chemicals.

Certain chemicals such as ferric, alum, and hydrochloric acid, are inherently higher temperature chemicals. To avert catastrophic failure of your chemical storage tank, a margin of safety is required to manage risk.

Poly Processing manufactures our tanks to meet your specific application requirements — including the type of chemical, the storage conditions, and the temperature of the chemicals you’re storing (among other considerations). 

Let’s take a look at the temperature factors you should keep in mind when purchasing a chemical storage tank.

Sodium hydroxide, also known as caustic soda or liquid lye, is commonly used to adjust pH levels in water and wastewater and can easily change hard water to a much closer approximation to neutral when injected into the water treatment system. Caustic soda can act as a corrosion inhibitor without the uneven distribution of calcium carbonate. Caustic soda is also used in the manufacturing of chemicals, rayon, cellophane, paper, detergents, soaps, and a variety of other products.

Phosphoric acid is one of the top ten chemicals used in the United States. Phosphates have many uses in the treatment of drinking water. Food grade phosphoric acid is common in the food industry, and it’s even used in pharmaceuticals, detergents, and textile pigments.
