The Safety and Security Benefits of a Bellows Transition Fitting

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 system like the SAFE-Tank with a sidewall fitting, it may be important to also install a bellows transition fitting.

What’s the Best Heat Maintenance System for SAFE-Tank® Tanks?

Maintaining the proper temperature of a chemical inside a SAFE-Tank® double-wall tank is often critical to safe storage. For example, sodium hydroxide at a 50 percent concentration will start to crystallize at or below temperatures of 60 degrees. For polyethylene chemical storage tanks, heating pads and insulation can maintain the specific temperature of the chemical you’re storing—even when your chemical tank is exposed to low air temperatures.

How Much Pressure Is Too Much for a Polyethylene Storage Tank?

When you design a chemical storage tank system, you have to consider the factors that impact the tank’s service life. Not only do you have to make sure that the tank material and fitting materials are compatible with the chemical you’re storing, it’s also important to consider the functionality of the tank — for example, how it responds to pressure.


You need to know exactly how much pressure your chemical storage tank can safely handle. This is an issue for every chemical tank, no matter what material it’s made of. Fortunately, cross-linked polyethylene storage tanks have remarkable durability compared to many other materials. That said, you need to know your tank’s pressure limits.

What You Need to Know About Tank Blanketing Systems

For many industries and facilities, oxygen is bad news for some chemicals stored in tank systems. Often, when the storage material comes in contact with oxygen, the substance oxidizes and degrades, or it can dry out. In any scenario, coming into contact with oxygen means you’ve lost product — which translates to less revenue and costs of replacement.

Tank blanketing helps prevent contact with oxygen, and Poly Processing is your partner for protecting your stored materials.

Keep Moisture Out of Your Chemical Storage Tanks

Bulk stored chemicals can become contaminated from two major sources: debris and moisture. As the product is emptied from the chemical storage tank, dirty air and moisture can be drawn into the tank. Temperature fluctuations can also cause the tank to expand and contract, so that it “breathes” contaminants in and out.

Maintaining chemical purity is essential in many industrial chemical applications, such as computer chip manufacturing, food processing, clean in place, and pharmaceutical manufacturing. Contaminated chemicals can become less effective, and more hazardous to your storage equipment. 

To prevent contamination, Poly Processing often recommends installing special accessories. Tank vent dryers and desiccant filters may be your best choice for keeping moisture out of the chemical storage tank.

Tank vent dryers can be especially valuable if you’re storing sulfuric acid. Because concentrated sulfuric acid is hygroscopic, any moisture entering the tank will be quickly absorbed into the chemical. If your supply of sulfuric acid isn’t frequently replenished, the top layer of acid will become more diluted, and more corrosive. As the contents continue to sit in the tank, the top layer of weak acid will corrode a ring around the inner tank wall.

What You Don’t Know About Flexible Connectors and Isolation Valves Could Hurt You

One of the most important design considerations of any chemical storage tank system is the use of flexible connectors and isolation valves. When paired correctly, these accessories will not only help ensure your storage tank’s longevity, they can also protect the tank from hinge points that cause dangerous leaks.
