Poly Processing Innovation Series: Enhanced Bellows Transition Fitting for Double Wall Tanks

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. Thus, when you install a tank-within-tank or double wall system like the SAFE-Tank with a sidewall fitting, it may be important to also install a bellows transition fitting.

Here's Your Comprehensive Chemical Storage Resource Library

As you’re researching and designing a chemical storage solution for your facility, the one thing you need more than anything else is information. The right information, plenty of it, and right where you can easily get it.

Poly Processing realizes how critical it is for customers like you to have quick and easy access to the information you need. That’s why we’ve invested so much of our own resources into building and curating the industry’s best chemical storage knowledge library.



Are You Using the Right Storage System for Hazardous Leachate and Condensate?

Leachate and condensate from landfills can contain hazardous materials — either from the waste itself or as a result of chemical compounds breaking down. Leachate is liquid that comes in contact with or is released from waste. Condensate is the liquid generated as a result of the gas collection and recovery process. In both cases, the liquid can be extremely hazardous and can create environmental disasters that take decades to recover from.

For Full Discharge, Don’t Rely on Cone Bottom Tanks

When it comes to a full discharge tank, cone-bottom tanks get the job done—except when they don’t. The fact is, cone-bottom tanks fall short on several fronts. 

Cleaning cone-bottom polyethylene tanks can be challenging. They require additional vertical space and safety precautions. And the tanks themselves cost a pretty penny — especially when you have to include a stand and basket to support the cone-bottom tank. Prices can skyrocket in today's market with the costs of metal and special coatings. Lead times for welded steel products are extremely long as well.

NSF/ANSI 61: Potable Water vs. Chemical Certification

Poly Processing is committed to ensuring that our polyethylene chemical storage systems are NSF/ANSI 61 certified. In our previous article on NSF, we looked at NSF/ANSI 61 and what it means to be certified. There can be some confusion about whether tanks or tank systems are certified to NSF/ANSI 61 and which certification is valid for which tank.

Is Your Polyethylene Tank Built For Your Process Temperatures?

Poly Processing’s standard crosslinked polyethylene tank systems can withstand process temperatures up to 100F — but that figure can be misleading, because there are different types of temperature to consider. 

For example, one of our customers in Texas asked about keeping a polyethylene tank outdoors in extreme temperatures:

Are Polyethylene (HDPE) Tanks UV Resistant?

Anytime a chemical storage tank is located outside, it’s exposed to harmful elements, such as sun, wind, and rain. Poly Processing recommends taking special considerations to protect the life of your storage tank, especially from damaging ultraviolet rays.

Are Crosslinked Double Wall Tank Systems Cost Effective?

There’s nothing more important than safely storing and handling hazardous chemicals. It’s your top priority to prevent leaks and spills of dangerous materials that can cause harm to employees, the general public, and property.

How Mechanical Stress Can Cause Tanks to Crack

We’ve written several articles about the importance of protecting your chemical storage tank from aggressive chemicals. Mechanical stress can be just as significant, causing polyethylene chemical storage tanks to crack. Mechanical stress occurs when the tank’s structure is compromised after a physical impact with another object, over pressurization, improper venting, or rigid plumbing that doesn’t allow natural expansion and contraction of the tank.

A Closer Look At the Toughness of XLPE Through Testing

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 in most cases 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.
