Purchasing a chemical storage tank is a significant investment. You want confidence and reassurance that the tank will give you the dependability and longevity that was advertised. A strong and transparent warranty shows that the manufacturer believes in and stands behind their product.

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.

No matter what chemicals you’re storing, it’s important to conduct routine annual storage tank inspections. These inspections are vital to keep the chemical tanks, fittings, venting and accessories in good working condition—and to avoid costly surprise failures. Even if the polyethylene tank is relatively new, a routine and careful visual inspection is recommended.

Some companies need to place their chemical storage tanks underground because of space limitations, or for aesthetic reasons. Steel tanks and reinforced tanks are built to withstand the external pressure that is applied underground, but what about lightweight plastic tanks?

While plastic storage tanks have many advantages over other tank materials, polyethylene is not the solution for underground storage. Here’s why.

You’ve done the hard part already. You’ve talked to a chemical tank expert at Poly Processing, designed your chemical tank system, double-checked that all the fittings you’ve ordered are compatible with your chemical, and you’re ready for your new storage tank system to be delivered.

Now that your order is placed and you’re preparing to receive your polyethylene chemical storage tank, there are some steps you need to have in place before your tank arrives. But what should you expect when your polyethylene tank arrives?

Purchasing and maintaining a chemical storage solution isn’t as simple as making a trip to the hardware store and picking out a tank that’ll do the trick. Unfortunately, many facilities make chemical tank purchases without the proper planning and execution, and the results are always costly.

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.

Poly Processing works diligently to produce each and every chemical storage tank built to spec, but if a tank is not installed correctly it could lead to damage, leaks, safety issues for personnel, and ultimately a shorter tank life. That’s why everyone should take chemical tank installation seriously.

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. 

Poly Processing Company manufactures high-density crosslinked polyethylene storage tanks for a wide variety of applications; but manufacturing is just one step in the overall process. A chemical storage tank is an investment, and it’s important to protect any investment. That’s why we take special care and precaution with your chemical storage tank, especially after it is rotationally molded and is ready to be shipped to your plant. Here’s a closer look at our process.
